Moore Industries is always thinking about solving real world problems customers commonly face. In addition to providing world class instruments, we often get requests from customers about mechanical mounting challenges and retrofit situations. Once again we have come up with a quick and convenient solution for cabinet and field installations. It is called the G-Type DIN-rail Adapter. This clever solution allows any Top Hat 35mm DIN-rail instrument to be immediately installed on existing G-Type 32mm DIN-rail.

The STZ is a dependable and accurate Smart HART temperature transmitter for use in Safety Instrumented Systems where dangerous processes occur. The SIL 3-capable STZ has a dual sensor input that provides backup and failover protection in case of a sensor failure.

Take a brief tour of Moore Industries’ North Hills, California, corporate headquarters and manufacturing facility - one of the last independent, privately owned instrument companies left in North America.

The SIL 3 capable SFY is ideal for use in your Safety Instrumented System (SIS) in a wide range of process and factory automation monitoring applications, providing reliable and accurate monitoring of frequency or pulse signals in SIS.

Instead of purchasing separate intrinsically-safe (IS) barriers when you need to connect devices and sensors from Class I Div 1 and Zone 0/1 hazardous areas to safe areas, you can connect directly to Moore Industries instruments that include built-in IS barrier technology, reducing costs. Watch to learn more about Moore Industries’ STZ, THZ3, and SPA2IS which feature our unique built-in IS barrier.

The Problem

In this application the gas company installed a RTU & Instrumentation for billing purposes to meter the gas sold to a large steel mill. The user installed their own Instrumentation at the same location (gas gate) and needs to compare the readings. 

The Solution

The signals from the user installed instrumentation is collected and sent back to the customer's HMI system using Moore Industries' NCS, NET Concentrator System Process Control and Distributed I/O. This was installed in a local junction box in close proximity to existing field instruments. The NCS is acting as a MODBUS master to the gas company's RTU while simultaneously collecting the signals from the end-users instrumentation (Pressure, DP, Temperature Tx’s).

The data arrives at the end-user's DCS and HMI over MODBUS TCP. The OPC* Server was able to utilize the MODBUS/TCP link to the NCS in order to efficiently share the metering signals with the HMI.

*OPC stands for OLE for Process Control.  It is a platform independent open standard that supports the exchange of data between industrial hardware and host systems (OPC Foundation, 2018).

A customer in Australia recently reported that one of Moore Industries' early products had been in use for well over 25 years, an EC-DCA Economy Direct Current Alarm (4-Wire). Moore Industries was proud to hear the product had been in constant service for so many years.

Figure 1. EC-DCA After 25 Years Of Service 

As part of Moore Industries' award winning line of products, the EC-DCA is one of the earliest products manufactured at the company. Although replaced by newer more advanced product designs such as the SPA2 Programmable Alarm Trip, the EC-DCA was a flagship product that demonstrated proven reliability and affordability with multiple input ranges, ease of adjustment by the user, AC or DC power input, and LED relay alarm status indicator, which was cutting edge in the early 70's.

Since many of the products developed are still in use, many of the manuals are kept online for users. If you'd like to see the manual, check it out online.

Moore Industries’ HART® Isolators provide highly economical solutions to common and costly problems that plague many of today’s “smart” process loops. Protect and enhance your HART investment with the 2-wire (loop powered) HIX or the 4-wire (line-mains powered) HIT.

Safely share the HART output of one transmitter with a secondary control or recording device. This allows for redundancy without further burden on or risk to a process loop. Protection from surges, spikes and transients of up to 1500Vrms safeguards I/O cards. Add the isolating capability of a HART Isolator to a loop to break the common galvanic path that can pass dangerous overloads from DCS to transmitter to PLC or vice-versa– even when the equipment is supposedly “isolated” already.

When temperature points need to be monitored in hazardous locations where explosive atmospheres can occur, consider using an Associated IS temperature transmitters, especially when the method of protection is Intrinsic Safety.  When Intrinsic Safety (IS) is chosen as the facility's protection method, intrinsically safe barriers for all of the RTD and TCs can be quite expensive, engineering intensive and space consuming. 

Download the PDF file

One solution to this problem is to install DIN rail temperature transmitters in the field, close to the process, that has built-in intrinsically safe barriers.  The THZ3 DIN rail temperature transmitter is considered an associated IS device because it has the IS barrier embedded in the transmitter so it can connect to temperature elements that are located in Class I Div 1 or Zone 0/1 hazardous areas.  Moreover, by implementing this strategy you eliminate the common drift and corrosion problems associated with long TC lead wire runs that lead to expensive and troublesome measurement errors.

Key Attributes:

• IS barrier built into THZ3, reducing needs for external IS barriers
• Eliminate errors due to TC extension wire
• Dual input capability and input corrosion detection

Thermocouple extension wire is not only expensive but can be a source or measurement error over time due to the integrity and composition of the extension wire.  When boiler tip monitoring is required consider using the NCS Net Concentrator System remote I/O.  The NCS accepts universal temperature inputs and is scalable for just a few or hundreds of I/O points.  Each NCS can then be placed on an Ethernet backbone for centralized monitoring.  If Ethernet is not an option the NCS also supports RS-485 MODBUS RTU networks.  Every NCS channel provides 500Vrms channel-to-channel isolation which is important for thermocouples.  Approved for installation in Class I Div 2/Zone 2 locations, the NCS is an ideal choice when you need a compact remote I/O solution.

Key Attributes:

• Universal temperature inputs
• Full channel-to-channel isolation
• Ethernet or RS-485 network support

Australia exported $34 billion in coal in 2015-2016 which has made it the largest global coal exporter by volume (Australian Government, 2016). There are 44,000 people directly employed in the coal industry making safety in mines an important issue. Moore Industries works hard to provide peace of mind with the reliability and ruggedness industry has come to depend on. The Moore Industries FS FUNCTIONAL SAFETY SERIES exida® SIL 2 and SIL 3 capable STA Safety Trip Alarm performs as a logic solver and acts on potentially hazardous process conditions to meet the needs of safe mine transportation. 

The Problem

Properly working underground coal mine hydraulics, used to operate the control of the braking system of the winder, is vital when moving mine personnel underground or bringing them to the surface. It is extremely important to ensure that the machine is stopped if low or high pressure is detected online from the hydraulic pump that operates the winder. With personnel safety involved, we can't afford any cable slip. 

The Solution

The STA, SIL 2 and SIL 3 Capable Programmable Current/Voltage Safety Trip Alarms are utilized for mine winder monitoring. The STA warns of unwanted process conditions, provides emergency shutdown, or provides on/off control in Safety Instrumented Systems (SIS) as well as traditional alarm trip applications. 

The STA makes an excellent choice for monitoring hydraulic pressure on the Mine Winder and assuring it will shut down the winder should any pressure changes occur.

The Problem

A pulp and paper mill had a black liquor BMS (Burner Management System) that per NFPA 85 requires that its safety logic system be totally independent from other logic systems.  The challenge was they required that key temperature and pressure signals also get monitored and recorded by their BPCS (Basic Process Control System). 

The Solution

The SSX Functional Safety Isolator with HART pass through capability was designed for Safety Instrumented Systems (SIS) and safety applications.  The SSX is designed to provide full isolation between a safety system and a non-safety system.   The two-wire loop-powered SSX has a passive input and is powered by the output loop side that is connected to the BPCS.  Therefore even if power is lost on the BPCS side of the loop, the safety loop functions without interruption.  According to IEC 61508 the SSX is a Type A device and per exida is suitable for SIL 3 applications.  An exida approved FMEDA report is provided for the SSX safety isolator to assist the safety practitioner with the safety loop implementation.

At the Hanford Site KW-Basin Sludge Treatment Project in southeastern Washington, the Department of Energy (DOE) employs multiple NCS Net Concentrator Systems to automate communications among numerous sludge conversion process skids. According to Hanford’s website:

“Nowhere in the DOE Complex is cleanup more challenging than at the Hanford Site in southeastern Washington. Hanford made more than 20 million pieces of uranium metal fuel for nine nuclear reactors along the Columbia River. 

Five huge plants in the center of the Hanford Site processed 110,000 tons of fuel from the reactors, discharging an estimated 450 billion gallons of liquids to soil disposal sites and 56 million gallons of radioactive waste to 177 large underground tanks. Plutonium production ended in the late 1980s.

Hanford cleanup began in 1989, when a landmark agreement was reached between DOE, the U.S. Environmental Protection Agency, and Washington State. Known as the Tri-Party Agreement, the accord established milestones for bringing the Hanford site into compliance with federal and state environmental regulations.”

However, as skids were progressively added, management recognized they were outgrowing manual intervention methods and NCSs (Net Concentrator System) were installed and programmed in order to allow automatic communication among the skids. Production personnel could now oversee the process from a control room rather than walking the production floor and could redirect communication links through various skids should some skids be underutilized or offline.

Each sludge processing skid includes a Moore Industries NCS that includes an Ethernet communications port and several channels of discrete and analog input/output channels. These channels monitor skid mounted gauges and control valves/gates. The NCS also has an embedded real time control engine that supports IEC 1131-3 control logic communication programming via ISaGRAF software.

Utilizing the ISaGRAF programming language, Hanford engineers were able to write their own programming instructions. The ISaGRAF program is also used to provide peer-to-peer Ethernet communications between other skids establishing convenient communications to share data.

Each NCS skid performs a particular part of the overall process, very similar to a batch process that carries out a particular complex recipe. During the process, each NCS skid collects, controls and monitors each part of its own process.

Every skid also monitors, triggers and makes available process flags, or status bits, to the control room personnel and other NCS skids. These status bits are used by other skids to determine if the next skid may collect the processed product from an upstream skid and begin processing the product itself (this being another sub-process).This continues for several levels in the process with each skid performing a different step in the sub-processes of the overall process. Some skids coordinate steps in the process (as described above) while other skids are the ‘traffic cops’ negotiating which skid is ‘available’ to handoff product to the next stage. The arrangement is such that skids may be taken ‘off-line’ or added ‘on-line’ with the automatic traffic cop logic to decide where product is to be rerouted. A separate skid acts as the ‘accountant’ keeping count on system productivity and bottlenecks including which skids are currently ‘off-line’.

The NCS’ ISaGRAF programming ease and flexibility, onboard Ethernet communications and peer-to-peer channel mapping allows new and existing skids to be automated or retrofitted as required.  This enables the Hanford site to handle the increased sludge processing throughput without overburdening their process team.

Supplemental Information For Tank Farm Application

Before converting a dry contact to an analog signal it is important to first determine what signal levels you will need.  Since the TMZ accepts a 4-20mA signal then we can choose any current values within 4mA and 20mA.  For this application we chose 'NOT FULL' to be equal to 20mA, and 'NEAR FULL' to be represented at 4mA. 

These two current levels will now indicate that the tank is ‘NEAR FULL’ or ‘NOT FULL’. The ‘NEAR FULL’ signal lets the DCS operator know that the tank should not be filled any further while the ‘NOT FULL’ indicates that the tank needs additional filling.

Using resistors in conjunction with a 24Vdc power supply, based on Ohm's law, allows a discrete or relay signal to be converted to an analog signal. Using ohm’s law the two resistors chosen for the desired analog signal levels were 1.5K Ohms and 6K ohms.  If the tank level is low, then the circuit includes both resistor values thus creating a 20mA signal to the TMZ. This 20 mA reports ‘NOT FULL’. 

V=IR

(24V/1500Ω) + (24V/6000Ω)

16mA + 4mA = 20mA

Otherwise, when the contact switches only the 6K ohm resistor is in the circuit and a current signal of ~4mA indicating ‘NEAR FULL’ (this occurs when the dry contact switch is open).

These two signal levels 4mA and 20mA will be converted to a logical “1” and “0” for MODBUS transmission.  Those TMZ specific programming details will be covered later.

Wiring Details

The bulk 24dc power supply, two resistors and contact terminals on the level transmitter need to be wired as a current input to the TMZ utilizing +I and COM terminals (See Figure 1).  

Figure 1. Top of TMZ highlighting connections

This wiring configuration creates a “failsafe” situation.  For example, should the level switch accidentally fail to open, or the 24Vdc become short circuited, then that tank is reported ‘NEAR FULL’ (4mA signal). A detailed wiring schematic can be found in Figure 2.

Figure 2. Tank Wiring and Setup

1. The float cage signal is converted using resisters (6000Ω and 1500Ω)and a regulated bulk 24Vdc power supply, connected to the TMZ, which is then connected to the RS-485 port (MODBUS) of the new WNM.  
2. The TMZ converts the analog signal to a MODBUS output that is connected to the WNM's RS-485 port.
3.  The WMN, also powered by the existing bulk24Vdc power supply, transmits signals wirelessly from the new tanks across the river to theWNM radio network connected to the DCS’ MODBUS network.

Details on Configuring the TMZ Transmitter to Communicate Data via MODBUS

Use the Model TMZ programming cable and free programming software to configure the Model TMZ for each tank. Assign a MODBUS address to this storage tank TMZ. Configure the baud rate, parity, etc. to match that of all other MODBUS devices.

Configure the Model TMZ ‘Custom Curve’ feature such that current less than 5mA is ‘0.0’ (‘NOT FULL’) and current above 19mA is ‘1.0’ (‘NEAR FULL’).  

(Note: This was chosen as the customer preferred the valve state for filling the tank to be 0 for open, and 1 for closed).  

For example, a simple four point custom curve like the following will work:

Figure 3. Four Point Custom Curve

WNM Configuration and MODBUS Network Wiring

Configure the Model WNMs as point-to-point radios and choose all other settings as required.  Moore Industries Application support pre-configures the WNMs prior to shipment from the Moore Industries factory, making the WNMs ‘ready-to-use’ upon arrival.   

Wire the Model TMZ and WNMs to the twisted pair MODBUS network.  See TMZ and WNM instruction manuals for RS-485 wiring diagram.

The Problem:

A Moore Industries customer wanted to monitor levels in new storage tanks that are remotely located on their tank farm and are not connected to their existing MODBUS network. The details of the customer’s existing tank farm, recent additions and monitoring needs include:

Twenty existing tanks are monitored using MODBUS continuous level sensors with data transmitted over a RS-485 twisted pair network.  

Five new remote tanks were added and need to be monitored, but were built with a level sensing device that only provided a dry contact output from a float cage to indicate level, no MODBUS output available.

The customer needs to convert the dry-contact output from the new remote tank level devices to a MODBUS signal that indicates two level states: NEAR FULL or NOT FULL and then transmit the data via MODBUS for monitoring at the Distributed Control System (DCS).

The new remote tanks could not be connected to the existing MODBUS network using twisted pair wire because they are located across a river from the existing tanks and the DCS.

The Solution:

Summary

Moore Industries Applications Engineers provided the customer with a cost effective and simple solution for monitoring their new storage tanks that utilized their existing technologies. After reviewing their situation the following issues needed resolving:   

• Dry-contact (discrete) output to analog signal conversion  
• Analog signal to MODBUS translation
• Getting the signals to the DCS from the tanks across a river

The first step involved using a pair of resistors and a bulk DC power supply to convert the dry-contact relay output from each tank’s float cage to a 4-20mA signal.  Next a Moore Industries TMZ PC-Programmable MODBUS Transmitter (Signal Converter) was used to read and convert the 4-20mA signal into MODBUS.  And finally the new MODBUS signals had to be connected to the existing MODBUS network across the river.  This involved installing a pair of Moore Industries WNMs (Wireless Network Modules) that utilized a point-to-point wireless network link across the river.

Figure 1. below shows the Tank setup with dry-contact outputs in a float cage, resistors, TMZ transmitter, and the WNM wireless module necessary to add the five new tanks to the MODBUS network and DCS across the river.

Figure 1. Tank Wiring and Setup

1. The float cage signal is converted using resisters (6000Ω [4mA for current loop one float level] and 1500Ω  [an 'additional 16mA' to signal other float level]) and a regulated bulk 24Vdc power supply, connected to the TMZ, which is then connected to the RS-485 port (MODBUS) of the new WNM. 
2. The TMZ converts the analog signal to a MODBUS output that is connected to the WNM’s RS-485 port.
3.  The WMN, also powered by the existing bulk 24Vdc power supply, transmits signals wirelessly from the new tanks across the river to the WNM radio network connected to the DCS’ MODBUS network.

Installation Specifics

Dry Contact Output and MODBUS Conversion

To solve the problem of getting level data from dry contacts into the existing MODBUS network, the Moore Industries application engineer suggested using a bulk 24dv power supply, a set of resistors and a TMZ MODBUS transmitter to be installed on each new storage tank. The TMZ (Model TMZ/HLPRG/MB/24DC [DIN]) is a very cost effective and flexible instrument. It accepts a direct signal input from a wide array of analog devices and converts the input to the standard MODBUS RTU (RS-485) communication protocol for direct interface with MODBUS-based monitoring and control systems.

The TMZ is powered in this application using a 24Vdc power supply at each new tank location. This same bulk power supply was then used in conjunction with resistors to convert the dry contacts to an analog signal (DC milliamps) that the TMZ could read.  The engineer connected the dry contacts’ two discrete terminals to the TMZ using a pair of resistors, 6000Ω and 1500Ω, to create a current loop signal representing the two different tank levels.

The TMZ translates the analog signal to a digital MODBUS communications signal.  Each TMZ was then connected to a RS-485 twisted pair network that was routed from tank to tank. Each storage tank TMZ has a unique MODBUS address assigned by the installer, which allows the DCS to distinguish individual tank level data.

Wireless Transmission

The Moore Industries WNM Wireless Network Module used in this application is a bi-directional, point-to-point or point-to-multipoint, 900 Mhz frequency hopping spread spectrum radio modem that includes a RS-485 port.  In order to connect the two MODBUS networks together across the river, a set of WNMs was used in point-to-point configuration.  Each WNM can also be simultaneously configured as a tank site source and a wireless repeater, allowing for virtually unlimited transmission range. Since the customer already had a MODBUS RTU data communication network, the WNM’s RS-485 port made it an ideal choice for this application.   

At the new storage tank, the engineer installed a Model WNM radio and connected it to the newly installed MODBUS RTU network. The MODBUS RTU communications signal received by the WMN over the twisted pair wires is transmitted by an antenna to the peer WNM radio that is now connected to the original MODBUS network and DCS across the river.  This essentially created an extension to the existing MODBUS RTU network through the radios.  This now allows bi-directional communication between the DCS and any tanks located across the river.

When Safety Instrumented Systems (SIS) are applied within a chemical facility you can’t always plan for every loop condition.  Sometimes input cards are active and sometimes passive.  Field transmitters are sometimes line powered (four-wire) which usually have active outputs, and sometimes they are passive (two-wire).  Moreover, is the field transmitter HART capable or not?

When those unplanned situations exist, you can turn to the Functional Safety Series SST Signal Isolator.  The SST is an exida approved four-wire SIL 2 capable isolator that provides superior noise rejection and full three-way isolation with HART pass-through capability.  Additionally, the input to the SST can be wired in the field as an active input (applies power to the two-wire field transmitter) or passive input.  The output of the SST can be ordered as active or passive.  Another very important feature of the SST that is very critical for an SIS, is that the output of the SST will track the input all the way to 0mA when it fails; as opposed to most other isolators that simply go to 4mA – which is always difficult to ascertain between a failure of the input or just 0% scale.

Key Attributes:

• exida certified to SIL 2
• HART pass-through capability 
• Output tracks to 0mA on failed input

An overpressure situation in pipes is dangerous and can lead to significant damages to property, pipe ruptures and even injuries and death. Having a system in place to prevent an overpressure situation is critical and one way to accomplish this is with a High Integrity Pressure Protection System (HIPPS).

A HIPPS provides a barrier between high pressure and low-pressure parts of an installation to prevent the release of fluid or gas into or otherwise contaminate the environment. An example of a HIPPS is an offshore well platform where the subsea oil or gas lines can occasionally present a harmful pressure surge in the pipeline. The HIPPS is designed to shut off the source before the design pressure of the downstream process is exceeded, avoiding a rupture of a line or vessel.

A HIPPS consists of three main components:

•Pressure transmitters
•Logic solvers
•Fast-acting shutoff valves

Many people assume that the logic solver has to be a safety PLC. But in many cases, a discrete logic device for each loop, which avoids the complications and expense of a programmable solution, is a sensible option. The “Logic Solvers for Overpressure Protection” white paper shows how discrete logic devices such as the STA Safety Trip Alarm are suitable for use while providing a flexible, low-cost and user-friendly solution.

While the safety PLC approach offers advantages for installations where there are a high number of field I/O safety loops, many plants have few such loops. For these plants, discrete logic solutions offer several advantages including creating a simple architecture, reducing cabling costs and avoiding the development cost of application programming.

The STA is easy to install with its wide range of power supply options and its small package that helps to keep it separate from non-safety instrumentation. In the event of maintenance due to transients or failure, it can be readily swapped out at a low unit and operational cost without interfering with the other processes in the plant. Local indication gives reassurance that the status of safety loops is reported directly.

The “Logic Solvers for Overpressure Protection” white paper shows safety engineers the steps needed to determine the right logic solver for their SIS. It shows the methodology and calculations for determining the applicability of logic solvers in SIL 1 and SIL 2 environments. It includes examples of system topologies and their associated Safety Integrity Level (SIL) calculations.

The STA Safety Trip Alarm is part of Moore Industries’ FS Functional Safety Series of instruments. Each of these instruments is designed and built in compliance with IEC 61508, the leading worldwide functional safety standard, and certified by exida for use in a Safety Instrumented System. In addition to our FS Series of products FMEDA (Failure Modes Effects and Diagnostic Analysis) reports available on many of our products that are used in safety applications.

Q: We have an existing Rosemount 1151DP tied to a Provox DCS. We also have a Moore Industries DDA 4-Wire Current and Voltage Alarm in the system to provide a Flow Switch Low and Flow Switch High interlock to our gas supply valves. Will newer products from Moore Industries provide more – or better – protection than the DDA?

A: The STA Safety Trip Alarm and SPA2 Site Programmable Alarm have alarm functions and can be used instead of the DDA. Both products have FMEDA reports which define the Probability of Failure on Demand and can provide a better degree of protection than the DDA. Additionally, the HIM HART Interface Module has alarming functionality that could also be used with the 1151DP transmitter.

The STA monitors the analog signal and is specifically designed for IEC 61508 applications. It is approved by exida for use in Safety Instrumented Systems (SIS) up to SIL 2 and in redundant architectures (1oo2, 2oo3, etc.) up to SIL 3.

Like the STA, the SPA2 can also monitor the analog signal and provides up to four alarms, a display, and an optional 4-20mA retransmission. The SPA2 is our most popular alarm choice for loops that are not specifically designed in accordance with IEC 61508/61511The HIM monitors the digital component of a HART signal and can be specified with up to two optional relay outputs, which can be configured for signal level alarms or for a number of HART status bits. It can be used to provide diagnostic coverage for a HART transmitter since it monitors the transmitter’s status bits.

Q: I need a 4-wire isolator and want to see if your MIT Multi-Channel Signal Isolator will work in my application. I have several 4-wire transmitters where I need to split and isolate the output signal to receivers that are passive (not powered). Will the MIT work provided that I supply 24Vdc power to the unit?

A: The MIT appears to be a perfect fit for your application. MIT’s input is passive, so it is compatible with the active output of a 4-wire transmitter. Because its outputs are active, they are compatible with the passive inputs of the receiver devices. In addition, it uses a universal power input, so it will accept 24Vdc power.

State regulations required a major pulp and paper company to monitor and record daily effluent water rates. This requirement was being fulfilled by sending an employee from their main control site to a remotely located pond three times a day to manually record water levels. This process was inefficient, time-consuming and didn’t provide them with real-time data. 

By installing a system utilizing technology from Moore Industries, the pulp and paper company implemented a system that is scalable for future installations while reducing employee workload and maintaining state regulatory compliance. This process is detailed in a white paper available for download on our website. It highlights how the use of the HCS HART Concentrator System and the NCS NET Concentrator System were critical in helping the company efficiently comply with government regulations.

HART flow level measurements at the pond site were converted to MODBUS RTU by a HCS and sent from a WNM Wireless Network Module at the pond to a receiver radio at the boiler control room. The information was relayed from the wireless radio to an HMI display and DCS/Historian by the NCS. This system enables the company to efficiently get accurate and required readings on the levels in their effluent water system.

WNIPT: Extracting HART Data from Smart Instruments

According to the FieldComm Group (formerly the HART Communications Foundation), there are more than 30 million HART-enabled instruments installed in chemical and process plants worldwide, and most process transmitters made today are HART compatible. The HART digital signal often contains valuable process measurements and other variables including instrument status, diagnostic data, alarms, calibration values and alert messages.

However, many systems fail to utilize the critical information available from HART-enabled transmitters, valve positioners, flowmeters and other "smart" devices. The February 2015 issue of the Australian magazine What’s New in Process Technology features an article from Moore Industries addressing these concerns. “Extracting HART Data from Smart Instruments” shows how a HART interface device such as our HIM HART Interface Module makes acquiring HART data simple. The data can be sent to a control system via analog signals, discrete outputs or serial communications.

Control Design: Process Skid Standardization

Another recent article highlighting Moore Industries was published by Control Design. In “Process Skid Standardization: What Manufacturers Want,” Dan Herbert discussed an issue common to OEM process skid builders. They keep their costs down when they can deliver the same product to as many customers as possible without customization. However, their clients often have specific needs that they want to be addressed by their process skid.

The article includes feedback by Moore Industries Senior Applications Engineer Jim McConahay, PE, who discussed how our NCS NET Concentrator System can serve as a universal MODBUS I/O interface and eliminate the need for most process skid custom interfaces.

For many temperature applications, getting a high level of accuracy is vital. A white paper from Moore Industries highlights how plant and site engineers can ensure the most accurate temperature measurement for critical applications. Available for download from the Moore Industries website, “A Practical Guide to Improving Temperature Measurement Accuracy” details steps that can also help end users improve the stability of their measurements and reduce calibration costs.

“A Practical Guide to Improving Temperature Measurement Accuracy” shows how to select the best sensor for a particular application and ways to improve the accuracy of the sensor you choose. In particular, it details the reasons why 4-wire RTD sensors are almost always the best choice for high-accuracy temperature applications. Using 4-wire RTD sensors eliminates the errors caused by a copper lead wire. The paper also explains the relationship between classes of sensors (such as Standard and Premium Grade thermocouples and Class A RTDs) and their error rates.

Along with learning how to select sensors, the paper also covers how to reduce errors caused by plant noise, using bath calibration to minimize RTD measurement errors and the relationship between remote I/O and temperature accuracy.

The white paper is written by National Sales Manager Gary Prentice, who graduated with a degree in Electrical Engineering from Lafayette College in Pennsylvania and has 36 years of experience working in the process control industry. He has encountered almost every possible temperature application over his career and is the perfect person to explain the benefits of using 4-wire RTDs.

You can get watch a tutorial on this topic by viewing a Webinar that Gary did a few months ago, which gives even more specific examples of how to improve the accuracy of your temperature measurements.

Moore Industries rep Soltex Chile S.A. recently exhibited at the Exponor 2015 show, which takes place every two years and focuses on the mining industry. It was held in Antofagasta, the main city in northern Chile, which is near the country’s world-class mining operations including copper, gold and nitrates. It’s an important show with plenty of opportunities to connect mining companies with instrumentation solutions.

Soltex’s booth at the show included Fieldbus Device Couplers and Power Supplies from MooreHawke, a division of Moore Industries. These products help to maintain and simplify communications between mining operations and control systems – even in hazardous areas. For example, the TRUNKGUARD Series 200 Fieldbus Device Couplers offer multiple benefits for engineers designing FOUNDATION fieldbus H1 and PROFIBUS PA networks:

• Auto Segment Termination: The patented technology prevents fieldbus segment failure from under- or over-termination, a major problem in fieldbus startups. The TRUNKGUARD's auto-termination feature assures that local parts of a fieldbus segment will continue with proper termination even if remote parts of that segment are accidentally disconnected. This prevents costly downtime and hazardous situations
• Short Circuit Protection: On detection of excess current on a fieldbus spur, the TG200 reacts immediately (20 microseconds) to switch spur current to a nominal trickle-level, rather than limiting the fault current to a fixed (and always higher) level as is typically done by competing units. With removal of the short, the spur is automatically reconnected to the fieldbus segment.
• LED Displays: Diagnostic LEDs positively indicate power status on each fieldbus spur, spur short circuits and the status of auto termination.

How about this for a ThrowBack Thursday post? One of the photos in our archive shows Mr. Moore at the groundbreaking for Moore Industries’ worldwide headquarters more than 40 years ago. Within six months of the groundbreaking, the company’s first employees had packed up their equipment, loaded it into moving vans and brought it overall in the course of one weekend.

Our building has come a long way from the groundbreaking. Today there are 158 employees here doing everything from manufacturing and engineering new products to handling sales and technical support. A mezzanine was added after the Hawke and Powers acquisitions to address the need for additional manufacturing capacity.

Moore Industries has come a long way in 40 years. Today the company is one of the most recognized and respected names in the world of process instrumentation with millions of units sold and installed in projects all over the world. Part of the reason that Moore Industries has remained so successful is that the company has maintained the same commitment to quality that it had when Mr. Moore founded it in his garage back in 1968. Making sure that customers get solutions to their instrumentation needs is paramount to our philosophy and guides us in the manufacturing and service of our products.

Q: I am looking for a differential temperature transmitter. We have used the SPT in the past and know that it will work, but I don’t know if you can use two inputs of two different 4-wire RTDs with the SPT.

A: The SPT has only four input terminals; therefore the number of RTD wires is limited. For differential temperature, one RTD can be a 3-wire and the other RTD can only be a 2-wire. The lead length compensation wire of the 3-wire connection compensates for the lead length of both RTDs. This is only useful if you make sure that all five wires have identical resistance.

To answer your question, you may use two 4-wire RTDs, but you cannot connect all of the wires unless you do it as described above. Wiring details are shown in Figure 17 of the installation manual.

A better option is to use our DIN rail mounted THZ3 HART temperature transmitter, a new model which can accept two three-wire RTDs and provide a differential measurement output. The configuration of the THZ3 is done by utilizing DTMs with PACTware on your PC or by using a HART compatible handheld device or HART host.

Details about the input connections of the THZ3 are in Figure 2.2 of the installation manual.

Model Example: THZ3/PRG/4-20MA/12-42DC [DIN]

Starting with the THZ³ and TDZ³, Moore Industries introduced a new way for our customers to configure our products.

The transmitters are both HART and DTM (Device Type Manager) programmable, which means they can be easily programmed and interrogated from anywhere at any time on a 4-20mA loop. This can be done with a standard HART handheld communicator, a HART-compatible host or with any FDT (Field Device Tool)-compliant host or program such as PACTware (available for download at our website) utilizing Moore Industries’ DTM.

At its core, the FDT model creates a unified standard for communications that take place between field devices and host systems. The DTM is the specific software component that contains data, functions and logic elements specific to the device. In the case of the THZ³ and TDZ³, the PACTware software is an interface that provides comprehensively advanced programming capability for thorough transmitter configuration.

One of the main benefits for end users of the FDT technology is that it frees them from constraints caused by being tied to a specific platform or communications method when configuring and monitoring devices. They can choose the best product for their installation and know that it can be easily integrated into their system. A single FDT frame application supports multiple communications protocols such as HART, PROFIBUS, FOUNDATION Fieldbus, DeviceNet, Interbus, AS-Interface and PROFINET IO with other protocols soon to follow.

For more information on the advantages of FDT technology, visit the Technology Benefits page of the FDT Group’s website. You can find additional information on Moore Industries' use of PACTware by reading our recent press release on the subject.

Q: I am interested in an ECA alarm unit, model #: ECA/4-20MA/DH1H1/24DC/DIN. I have three questions:

1. I have a need for three different trip setpoints based on the same transmitter input. How can I accomplish this with the ECAs? Can I use two ECAs using the second ECA with a 1-5VDC input or can the 4-20mA signal be run in series through both ECA inputs?

2. Do I need to specify the -RF option to get the RFI protection? And is the testing for both radiated and conducted susceptibility (RS103, CS114, CS115)? Is it possible to see the test report for the EMI/RFI testing?

3. Is DIN-rail the only mounting option?

A: To answer your three questions:

1. Your 4-20mA signal can be connected in series to the inputs of more than one ECA, each of which with a 50 ohm load on the loop. Alternatively, you can use a SPA2 Limit Alarm Trip (Model #: SPA2/HLPRG/4PRG/U [DIN]) which has four setpoint relay outputs.

2. The ECA-DIN has RFI/EMI Protection to 10V/m, 20-1000MHz for which the trip point would not be affected by more than 0.1% of span. It conforms to the following EMC specifications:

EN50081-2, 1993, Generic Emissions Standard, Industrial Environment.

EN50082-2, 1995, Generic Immunity Standard, Industrial Environment.

EN61010-1, 1995, Safety requirements for electrical equipment for measurement and control use.

3. Both the ECA-DIN and the SPA2 are designed for DIN rail mounting; however, we also offer them with options for flange mounting.
