Q. We have been using 3-wire RTDs in our process for years and are required to check the calibration once every 6 months. Each time we have checked the sensors we’ve noticed they have drifted. This requires us to re-calibrate our temperature transmitters. Do you have something you can suggest to help us reduce the drifting problem we regularly see in these sensors?

A. The problem with 3-wire RTDs is that the lead wires build up small amounts of corrosion causing a lead wire imbalance which results in measurement errors. If these are Platinum 100 ohm RTDs, just one ohm of resistance change on any lead wire can represent a +4.7°F degree error. We suggest using 4-wire RTDs which compensate for unequal resistance in the lead wires. For this to be an option your temperature transmitters need to accept a true 4-wire sensor input. Some temperature transmitters, PLCs, and DCS input cards only accept 3-wire RTDs. Others indicate a place to connect a fourth wire, but do not use it for measurement.

You can also use Class A RTDs with 4 wires and a transmitter that can accept and be calibrated with a 4-wire RTD. Our Class A element RTDs with a .06% accuracy have been cycled for 1000 hours, and will hold their accuracy for a 5 year period.

You can learn more about using 3-wire and 4-wire RTDs in the white paper: A Practical Guide to Improving Temperature Measurement Accuracy. 

These Moore Industries temperature transmitters are designed to accept true 4-wire RTDs: RIY, STZ, TCS, TDY, TFZ, THZ, THZ3/TDZ3, TPZ, TRY, TRX. For these and other Moore Industries temperature solutions, visit our Temperature Sensors, Transmitters and Assemblies page.

Q: I would like to use either FDY/PRG/4-20MA/12-42DC [HPDN] or FDY/PRG/4-20MA/12-42DC [BH2NG] and I want to install it in a control panel enclosure rated Type 4X. I need to ensure it is suitable for Class I, Div 2. Which one is the best solution?

A: The FDY/PRG/4-20MA/12-42DC [HPDN] without the BH2NG enclosure is Class I, Div 2 rated. It meets the Div 2 requirements when installed in your Type 4 box. You can download the certificate here.

The FDY/PRG/4-20MA/12-42DC [BH2NG], is an explosion proof transmitter approved for use in Class I, Div 1 hazardous areas. This is the same FDY device except it is housed inside the explosion proof/flameproof BH2NG enclosure. This BH2HG enclosure is also rated Type 4X & IP66 which means that it offers sufficient environmental protection to allow it to also be classified as a Class I, Div 2 or Non-Incendive device. The FDY/PRG/4-20MA/12-30DC/-ISF with the [HPDN] housing designation or enclosed in a BH type housing carries intrinsically-safe approvals.

Q. I have a temperature application that requires a 12-inch thermowell which can withstand a high temperature of 2,000°F. Most of what we have been using becomes brittle and breaks off at the tip. What would you suggest we use, and what type of sensors do you have that will work for us?

A. We have several different types of metals we can suggest with maximum temperatures up to 2,160°F. Materials that will work well for the thermowell in your application are SS446, SS310, and Inconel 600.

For the sensor type, we recommend a thermocouple Type “K” with Inconel 600 material for the sheath. Also, using 2-inches of thermal-lagging for the thermowell will reduce heat going into the head.

If possible, remote mount the temperature transmitter away from the process connection. Even though Moore Industries temperature transmitters are rated up to 185°F, it could get too hot inside the head if it were mounted directly on top of the process. If you must mount the transmitter near the process connection, we suggest using a stainless steel housing and a ceramic terminal block to terminate the sensor at the process.

Q: We have an R-BOX in a Class 1 Div 2 location with a 120VAC instrument inside. Is this enclosure rated for this atmosphere? It does not appear to have a very good seal for this environment.

A: The R-BOX was designed to meet a Type 4X and IP66 rating, which is suitable for housing a Div 2 approved device. The hazardous area protection is provided by the non-incendive nature of the Div 2 rated device mounted inside. The enclosure simply needs to provide protection from the ambient elements or other flying conductive material.

Q. We want to measure bearing temperature in our motors to alert us of overheating. We have used a type of sensor which inserts into the side of the motor, but they leak and fail often. We would like to put something on the surface of the motor outside of the bearing housing, but we do not want something welded to the housing. What can you suggest?

A. The best solution for your application is a WORM sensor with a Magnetic Pad (-MPAD). The -MPAD has 40lbs of attraction and will hold up to a vibrating surface. We also suggest adding our 30G option to the RTD, in order to protect the RTD element inside the sheath from high vibration during motor operation. Standard fixed length sensors cannot withstand this vibration over time. The -MPAD with WORM sensor is easy to install on any ferrous metal surface.

With electronic equipment making up much of process hardware, the potential for system noise and interference with process signals can come with the package. Frustrations from downtime and troubleshooting in your plant can be avoided by understanding the principles of signal isolation, conversion and interfaces. A comprehensive resource for determining which instrumentation to use, and how to use it, is Moore Industries’ Signal Isolators, Converters and Interfaces: The “Ins” and “Outs” White Paper. It has recently been updated and is ready for download from the Technical White Paperssection of the Moore Industries website.

The white paper delves into the important ways signal isolators, converters and interfaces can be used and what to look for when specifying products for applications. It also expands on the specifics related to isolation in Safety Instrumented Systems (SIS) which are used to control dangerous processes and require installation of SIL-capable instruments.

Intrinsic safety is increasing worldwide as a method of hazardous area protection with monitoring and measurement instruments. Significant savings, both initial installation and ongoing maintenance costs, can be realized in intrinsically-safe (IS) facilities or projects by selecting an associated apparatus that encompasses the required IS barrier protection for your system.  Available for download from the Technical White Papers section of the Moore Industries website, “Associated Apparatus: The Safe and Most Affordable IS Solution” gives you a brief introduction to intrinsic safety, the different components in an intrinsically-safe system, and the two different types of barriers.

Written by Tina Todd, Director of Engineering at Moore Industries, this paper explains the basic differences between simple apparatus with separate intrinsic safety barriers and associated apparatus with intrinsically-safe field connections. It addresses why selecting an associated apparatus which includes the IS barrier provides the most economic and effective use of IS technology. Additionally it addresses design, installation and maintenance considerations in selecting the best approach when choosing an intrinsic safety solution.

The techniques outlined in this paper are most applicable to the industrial process control sector including such industries as oil and gas production, oil refining, petrochemical, chemical, mining, pharmaceuticals, food & beverage, and pulp & paper.

Q: I am evaluating the SIX 2-wire Signal Isolator and Converter. Is this device auto-calibrated or will we need to calibrate it ourselves? Does it require two separate power supplies? The specs state that the output is loop powered but I am not clear on the input. Also, is it a problem if we supply both the input and output with the same power source?  In our case, it would be the 53.5VDC power supply in the loop currently.  We would need to run a parallel path. The input is intended to be a 4-20mA.

A: The SIX is provided pre-calibrated from the factory for the input and output indicated in the model number. The device has potentiometers accessible on the front panel for making adjustments to the zero and span.

The SIX derives its operating power from the voltage that is applied to its output. It consumes 12V of the available voltage applied to its output. The SIX accepts a voltage or current input. If the input is 4-20mA, then the SIX will add 50 ohms of impedance to that loop.

Regarding supplying both the input and output with the same power source, the primary purpose of the SIX is to provide input to output galvanic isolation. Using the same power supply for both would defeat that isolation.

Q: We have been using your SPA series temperature transmitters in our hydroelectric power plants with excellent results. These devices have high protection against electromagnetic interference. We would like to purchase temperature transmitters for head mounting and rail mounting that have the same high level of isolation and protection against electromagnetic interference. The sensors are 10 Ohm Cu three wire RTDs and they represent the temperature of generator windings in the hydroelectric power plant.    

A:  Model SPA/TPRG/2PRG/U/-AO [DIN]  provides 0.25 mA RTD excitation current.  If it is performing well then our PC configurable temperature transmitters, which have the same excitation current, should also perform well. In that case we recommend the TRY series. The head mount style is model TRY/PRG/4-20MA/10-42DC [LH2NS]

If your SPA has the SP2 option instead (Model SPA/TPRG/2PRG/U/-AO-SP2 [DIN] ), that option provides 5mA of excitation current to the 10 ohm RTD instead of the usual 0.25mA. This ensures that a robust input signal from the RTD to the SPA resists interference from the generator’s very strong electro-magnetic fields.

The choices available for a head mounted transmitter with similarly high current RTD excitation are limited. Bear in mind that the objective when designing RTD temperature transmitters is to reduce the excitation current as much as possible to minimize self-heating of the RTD, thereby maximizing the measurement accuracy.

Also due to the reduced power budget of loop powered transmitters there isn’t sufficient power available for the 5mA excitation current of the SP2 option.  

A possible solution is one of our older analog loop powered transmitters, the RBX series, which has a relatively high excitation current of 1mA.  The RBX, however, is a strictly analog design and must be specified according to the intended resistance range instead of temperature span. For example, for 10 ohm Cu and 0-200 deg C, the resistance is 9.035  to 16.776 ohms. The span is 7.741 ohms. The 7.741 span falls within the 3W5-10 input range. 

The head mounted model number is: RBX/3W5-10/4-20MA/12-42DC/-EZ9 [BH2NS].

Q: I need confirmation that the THZ2 is a functional like-for-like replacement for the THZ and that basically it will perform the same.

A: With the exception of the THZ/PRG/4-20MA/12-42DC [DH2NG], which has an integral display, the THZ2 has all of the functions of the THZ and the same form and fit.

However, we suggest you consider the newer THZ3, since the THZ2 is being phased out (although it will continue to be available while supplies last). The THZ3 has all of the functions of the THZ2 and the same form and fit. The THZ3 offers additional functionality over the THZ2, can accept two sensor inputs, and utilizes PACTware for PC configuration in addition to HART programmability. 

Other features found in the THZ3 that are not included in the THZ are:

•  Backup and Fail-Over Protection allows either of the sensors or inputs to be designated as the primary measurement, with the secondary input acting as the backup sensor in case of primary sensor failure.
• Average and Differential Measurement allows you to average the two input measurements or select the differential (A-B or B-A) or absolute differential between the two inputs.
• High-Select and Low-Select Feature enables the transmitter to continuously monitor two separate inputs and designate either the highest or lowest input to represent the analog output.
• Dynamic Variable Mapping permits the user to assign either input or the calculated result of inputs to any of the four HART variables (PV, SV, TV or QV) that can be read by any HART compatible host system.
• Smart Range Alarms offer four HART alarms set to any input or calculated input that detect when the variable is within or outside user preset limits.
• High Availability Option enables the user to select how the AO behaves when there is an input failure or out-of-range value detected by the transmitter. This prevents nuisance alarms on startups or batch process shutdowns.

Q: You have a product called HART Interface Module that will pull the 2nd, 3rd and 4th HART variables from a smart HART transmitter and create one 4-20mA signal for each. Do you have or know of an instrument that will take three 4-20mA signals into it and place themdin on one 4-20mA signal as the 2nd, 3rd and 4th variable? I would like to read three transmitters on one 4-20mA signal by reading the variables on my DCS System.

A: We have three products that can take multiple analog inputs and provide that signal data in the form of HART protocol. Those products are the TCM and THZ3 / TDZ3, which are temperature input devices that can take a 4-20mA input across a resistor (shunt) as a mV input.  

The TCM is a 16-channel temperature input module that can be polled by a HART master using a device-specific HART command. This HART command retrieves all 16 channels of PV data in one HART message packet.

The THZ3 Dual Input Smart HART DIN-Rail or Field Mount Temperature transmitter can accept two (but not three) 4-20mA signals and write them to two of the HART dynamic variables riding on the analog 4-20mA output signal.

The TDZ3 has the same functionality as the THZ3 but includes a display and can be field mounted in hazardous or non-hazardous areas or mounted on DIN-Rail.

Moore Industries’ Functional Safety Line Card gives you all the information you need to know about our line of products for process safety-related applications. This includes our line of FS Functional Safety Series products designed and built to strict IEC 61508 standards, ensuring safe and reliable function – particularly in environments where hazardous or emergency situations are likely to occur.

As with other Moore Industries line cards, the Functional Safety Line Card is available as a PDF download at our website. It gives an overview of the instrumentation that makes up our FS Functional Safety Series:

• STZFunctional Safety Dual Input Smart HART Temperature Transmitter
• SSX and SST Functional Safety Isolators and Splitter
• STA Functional Safety Trip Alarm
• SRM Functional Safety Relay Module
• SLD Functional Safety Programmable Display (2-Wire)
• SFY Functional Safety Frequency-to-DC Transmitter with Display

Along with the product information, the Functional Safety Line Card has valuable information for selecting the right Functional Safety instrument. The charts and safety-related information help determine whether instruments meet the required Safety Integrity Level (SIL) for use in a Safety Instrumented Function (SIF).

Q: I am looking to take a signal from an analyzer and send the analog output signal to four different locations. Do you have a product that can help me with this?

A: We offer a 4-channel output loop powered isolator and a line powered single input to dual output isolator.

If the receivers at the four locations can supply loop voltage to their respective 4-20mA inputs, then the 4-channel output loop powered MIX isolator (Model: MIX/4X4-20MA/4X4-20MA/12-42DC [DIN]) will work. Wire your 4-20mA signal in series to the four inputs of the MIX.

If the receivers at the four locations have passive (sinking) 4-20mA inputs, then you can either use two of the line powered ECT splitters or two of the dual channel MIT isolators (Models: ECT/4-20MA/2X420MA/117AC/-TX [DIN] or MIT / 2XPRG / 2X4-20mA / U [DIN]). Wire your 4-20mA signal in series to the inputs of the two ECT/MITs.

The SIL 2/3 capable STA Safety Trip Alarm performs as a logic solver and acts on potentially hazardous process conditions by providing emergency shutdown or early warning indication in Safety Instrumented Systems (SIS).

In response to customer feedback, the STA has been updated to provide more flexibility in handling input faults. This allows for spurious alarms to be minimized and for alarms to be cleared without power cycling or needing physical access to the unit.

New configuration options that have been added include:

• Out-of-range input tolerances can now be set from 0-5%. There is a 2% restriction in use for safety systems.
• Startup delay from 0-120 seconds, which allows instruments providing input to the STA to stabilize on power up.
• Input fault alarms can now be non-latching or cleared remotely using the Manual Reset terminals.

For more information, please download the latest versions of the Data Sheet and  Installation Manuals available at the STA product page.

Rob Stockham of Moore Industries-Europe delivered lectures earlier this month on the topic of “Producing High-Reliability Software for Instruments Used in Safety Applications.” The lectures covered the specifications, design, production and testing of firmware suitable for use in applications up to SIL 3 as defined by BS IEC 61508 Part 3.

The first lecture was to students at Liverpool John Moore’s University in the morning. This was followed up with an evening talk to the Central North-West Local Section of the Institute of Measurement & Control. A total of 39 people attended the two lectures.

“Thanks to Rob Stockham for presenting these lectures,” said Tom S. Nobles, Central North-West Programme Secretary for the Institute of Measurement & Control. “It’s particularly kind of him to lecture to the students. These young people represent potential future customers as well as people who need to interface with the industry and the measurement and control community in general. The attendance in the evening was also great, showing the interest and possible concern that users have about this subject.”

Rob said that he received positive interactions and feedback on the topic, although it was clear that more education is still needed on the topic. He was pleased that the EMPHASIS assessment tool and nuclear qualification of smart instruments were mentioned several times by lecture attendees.

Q: I want to replace a THZ Temperature Transmitter (Model THZ/PRG/4-20MA/12-42DC [DIN]) with a CPT PC-Programmable Temperature Transmitter (Model CPT/TPRG/0-20MA/117AC/-C-RF [DIN]). The THZ unit we are replacing gets its power from the 4-20mA current loop while the CPT unit is going to be powered by 120Vac. Does the CPT need to be specified as "source" or "sink" to work as a drop-in replacement for the THZ unit?

A: The default version of the CPT provides voltage on its output (source). If you would like the output to be passive so it can be wired to an active (voltage supplied) input, specify the "-SINK" option. The CPT will still require 120Vac power on the power terminals.

Note that the newer two-wire output loop powered THZ³ Dual Input Smart HART Temperature Transmitter (Model THZ3/PRG/4-20MA/12-42DC [DIN]) is now available.

Q: My concern is that we will damage the unit or the equipment it is connected to it if we specify the wrong type of output. This unit will be connected to an Allen Bradley 4-20mA analog input module. The previous THZ device got its power from the analog input module so I believe the correct specification would be "sink" for the CPT. Is this correct? Also, can the "source" or "sink" option be changed in the field or does this have to be set at the factory?

A: You are correct that you will need to choose the "-SINK" option on the CPT. The choice of "source" or "sink" for the CPT must be specified in the model number and supplied from the factory that way. It cannot be field changed. Your complete model number for this application would be: CPT/TPRG/0-20MA/117AC/-C-RF-SINK [DIN].  Note that you have also selected an auxiliary alarm contact and enhanced RFI/EMI protection.

Moore Industries had a very successful time at the Emerson Exchange show last week in Denver. According to Marketing Manager Tom Watson, a prime position next to Emerson’s “theater” helped to ensure a steady flow of traffic to the booth during the event.

“For the first day of the show on Monday, traffic to the Moore Industries booth was the heaviest that I have experienced in any previous Emerson Exchange,” Tom said. “It was non-stop with visitors from all over including Kuwait, Trinidad & Tobago, Argentina, Saudi Arabia, Peru, Ecuador, Chile and the US. Our booth was located right next to the Emerson ‘Theater’ at one end of the hall which had a steady stream of conference and exhibit attendees listening to a variety or presentations. In the Moore Industries booth, we talked with a wide spectrum of visitors from veteran Moore Industries customers to users who were unfamiliar with our company and products. There was significant interest in Fieldbus solutions from South American visitors, and several people asked about our HART and Functional Safety products.”

Moore Industries’ next event is the FieldComm Group’s FOUNDATION Fieldbus End User Seminar in Long Beach, CA on November 5. Registration is currently open for the show.

Q: I need to use the STA Safety Trip Alarm in a hardwired panel. Is it possible to configure two different levels of alarm for each of two relays in the STA, in order to have two different trips (one for each relay)?

A: Only one set point can be assigned to each alarm relay of the STA. However the dead-band is adjustable from 0% to 100% of the input span. Therefore you can specify one signal level at which the relay engages and another for when it disengages.  If your input signal is 4-20mA, you can connect it in series to the inputs of two STAs in order to obtain 4 independent relay/setpoints.

Q: To clarify my situation: if I have a 0 to 100 bar transmitter, can I trigger Relay 1 at 25 bar and Relay 2 at 75 bar? We need to do this in order to shut down two different pieces of equipment at these pressure levels.

A: This is a typical function of the STA. One relay setpoint is often used for a warning at one level while the second relay setpoint is used for shutdown at the next level.

The SIL 3-capable STZ Functional Safety Dual Input Smart HART Temperature Transmitter has several features designed to reduce process interruptions safely in your SIS. One of the most important is the new dual sensor input that allows for Backup and Fail-Over Protection, which is the topic of a new Problem Solver on the Moore Industries website.

This example of a potential real-world application focuses on reducing the risk of exothermic reactions in batch reactors. These reactions can create thermal runaways where rising temperatures can lead to dangerous conditions. Backup and Fail-Over Protection allows either of the sensors or inputs to be designated as the primary measurement, with the secondary input acting as the backup sensor in case of primary sensor failure. This helps to mitigate potential thermal runaways before they become dangerous.

Q: We are in need of a signal converter that converts a 4-20mA logarithmic signal into a 4-20mA linear signal. We need one input and one output per device. Do any of your devices perform this function?

A: We offer several models of signal converters which have look-up table linearization/characterization capability.

The SIY is an output loop-powered unit that can be configured for up to 85 ordered pairs. With this model, each ordered pair must be keyed in using the provided configuration software.

The CPT is a line-powered model that can be configured for up to 128 ordered pairs. The ordered pairs are computed with a spreadsheet, saved as a two column CSV file and then loaded into the provided configuration software. The configuration is then loaded into the CPT.

With both models you specify the X and Y values so you can cluster points at the most non-linear part of your table.

Q: We are a boiler/burner company dealing with a rising amount of computer-based burner controls. We have installed several and have some blowers that are controlled by VFDs (Variable Frequency Drives). We have run into issues with noise on certain systems. We get occasional problems with 4-20mA feedback from the VFD despite going through the proper grounding techniques. We are wondering if installing an opto isolator on the feedback loop might eliminate our issue. We have used the SIX Signal Isolator many times on the signal going to the VFD to offset impedance issues on the VFD. Can we put an opto isolator on both signals?

A: Whether the SIX or another isolator will cure your problem depends on the nature of the noise and how the loop is energized. Sometimes you can install an isolator without additional analysis and see if it works.

If you have data about the noise, compare it to the noise rejection specification of the isolator. For example, the Common Mode Rejection for the ECT-DIN Signal Isolator exceeds 95dB @ 60Hz with a limit of 1500 Vrms.

When selecting the appropriate isolator, take into account which device is providing the loop voltage on the input and output sides. Per the ECT datasheet, you can see that it is available as an output loop powered, input loop powered or line powered device.

Senior Sales Engineer JR Madden took the Moore Industries Instrumentation Trailer on the road to the Wyoming Oil and Gas Fair in Casper last month. He was able to get a prime “parking space” for the trailer as well – right between the main parking lot and the show entrance. It was a very popular show with an estimated attendance of 1,000. JR said that the attendees who stopped by the trailer were high-level employees interested in our instrumentation for the oil and natural gas industries.

Being able to set up shop outside of the show floor is an excellent advantage of having the Instrumentation Trailer. JR is able to get on the road and bring our range of instrumentation solutions to the public, both by attending trade shows and going on site to customers in conjunction with our reps.

Moore Industries will be at another big event next week as we will be one of the exhibitors at the Emerson Global Users Exchange 2015 from October 12-16 in Denver. If you are attending the show, make sure to stop by and see the latest instrumentation. We’ll be at Booth 212 next to the Integrated Operations section.

The Moore Industries SIL 3-capable STZ Functional Safety Smart HART Temperature Transmitter family, part of the FS FUNCTIONAL SAFETY SERIES, is a dependable and accurate temperature transmitter for use in Safety Instrumented Systems (SIS) where dangerous processes occur. The STZ has been certified by exida after rigorous evaluation to ensure conformance with strict IEC 61508:2010 standards for safety-related applications.

The STZ offers a dual sensor input that reduces process interruptions. Backup and Fail-Over Protection allows either of the sensors or inputs to be designated as the primary measurement, with the secondary input acting as the backup sensor in case of primary sensor failure. The dual sensor input also allows 

for Average and Differential measurements along with High-Select and Low-Select options.

The STZ also features Moore Industries’ Device Intelligence, a series of features designed for smarter control and monitoring including:

• Sensor drift and corrosion detection that checks and alerts users when the sensor is drifting out of a preset range or when the resistance due to corrosion exceeds set parameters.
• Smart range alarms with four HART alarms – set to any input or calculated input – that detect when the variable is within or outside of user preset limits.
• A High Availability option that enables the selection of how the AO behaves when there is an input failure or out-of-range value detected by the transmitter. This helps prevent spurious trips or nuisance alarms in Safety Instrumented Systems (SIS).
• Input simulation capability allowing manual input of a direct or calculated value. This essentially simulates a real input, allowing users to test the AO or any HART diagnostic and range alarms – which assists in proof test procedures.

The STZ is HART 7 compliant with exception-based reporting and dynamic variable mapping. It is HART and DTM programmable with user-oriented basic configuration for fast and accurate setup. Utilizing the HART DD, it can be configured and interrogated on the 4-20mA loop via any HART handheld communicator or HART compatible host. To prevent unauthorized or accidental reconfiguration of the STZ while it’s performing its safety function, it has an added security feature to allow users to set HART communication into a Read Only or Off mode. Users can also program or monitor the transmitter with any FDT compliant host or program such as PACTware using the STZ DTM.

The intrinsically-safe -AIS option for the STZ-DIN allows direct connection of sensors located in hazardous locations by including an embedded intrinsically-safe barrier in the front end of the STZ-DIN. The STZ-DIN -AIS is an associated apparatus suitable for mounting in Non-Hazardous or Class I, Division 2/Zone 2 hazardous locations with sensor input terminals connected to sensors or equipment in Class I, II, III, Division 1/Zone 0/1 hazardous locations.

See a video highlighting the key features of the STZ at our Interface Solution Video Library.

The STA Safety Trip Alarm datasheet and installation manuals have been updated. The new change reflects the addition of a Universal power supply to the unit. Previously, customers needed to select either a 24DC or UAC power supply. The new Universal power supply accepts any power input range between 21.6-375Vdc or 90-260Vac.

Adding the Universal power supply option simplifies the ordering process for customers. In addition, it makes it easier for customers to plan additions or upgrades to their facilities without having to worry about the type of power being used.

The specifications in the datasheet and installation manuals have also been changed to reflect the new Universal power supply. Updated specs include Power Supply, Power Consumption and Alarm Trip Delay. In addition, the Relative Humidity specs have been updated.

Sensor drift is a common problem that can lead to inaccurate temperature measurement readings. It can be caused by several factors including environmental contamination, vibration or extreme temperature fluctuations. Because this drift causes the measurement error to get worse over time, it’s not possible to calibrate out the error. Traditionally, reducing inaccurate measurements caused by sensor drift has meant undertaking a regular and time-consuming preventative maintenance calibration program.

You can avoid having to do constant preventative maintenance to avoid inaccurate temperature readings by using the THZ³ and TDZ³ Dual Input Smart HART Temperature Transmitters. The Drift Alert feature lets you configure the transmitter to monitor the differential between the readings of the dual sensors. If the readings drift apart by an amount greater than your preset range, an out-of-range warning or alarm is triggered. This alerts plant engineers that maintenance is needed.

This sensor drift alert can be configured to send a drift alert via HART or you can drive AO to your preferred fail state.

If your BPCS does not have HART inputs cards, you can use the HIM Smart HART Loop Interface and Monitor to deliver the HART alarms and diagnostic data via relay contacts.

Q. We would like to use the ECA-DIN in a seismic application. In a worst case scenario of an earthquake, the ECA-DIN must retain its position. We are concerned about the robustness of DIN rail mounting. Is the ECA available with a bolt down option?

A. We can supply the ECA with side flanges for more robust gearplate mounting instead of the usual DIN rail mounting.

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.

The CPMS Cathodic Protection Monitoring System monitors above and below ground impressed current cathodic protection systems to ensure that proper corrosion protection is in place and operating at the right levels. The CPMS Cathodic Protection Monitoring System monitors above and below ground impressed current cathodic protection systems to ensure that proper corrosion protection is in place and operating at the right levels. 

Part of Moore Industries’ NET Concentrator System® family of intelligent distributed I/O, the CPMS monitors the critical current and voltage levels of one or two transformer rectifi ers used in cathodic protection systems. Each module provides four or eight, fully-isolated analog input channels and four discrete (contact closure) inputs. It “concentrates” this data onto one or multiple communication links, and transmits it long distances back to one or more host DCS, PLC or PC-based control systems. 

The CPMS accepts up to four discrete (contact closure) inputs from the monitored system. Using an internal control engine, the CPMS can be programmed with internal set points that relate to normal operating conditions within the cathodic protection system. Should monitored parameters go outside of selected limits, or if power to the cathodic protection system is lost, the CPMS alerts of the unwanted conditions at the control system over the data link.

In addition to operating in a stand-alone mode, the CPMS integrates with any of Moore Industries’ NET Concentrator System’s analog, temperature, discrete and relay I/O modules. When coupled with the ROM (Relay Output Module), relay outputs can control rectifiers using accurate GPS time to facilitate taking cathodic protection reference electrode readings.
