Alarm Trips: The Ups and Downs
When something happens in your plant, whether it's a signal peak or fall, you have to know about it. A limit alarm trip can be a life saver, triggering the response needed to maintain normal, safe operations. Gary Prentice of Moore Industries covers how to use alarm trips to monitor a process and activate a warning or shutdown in the event of an undesirable high or low process condition.
Bridging the Intrinsically-Safe Fieldbus Disconnect
Engineers have long struggled with how to use Fieldbus in hazardous areas. The installation of Intrinsically-Safe (I.S.) fieldbus has typically required the use of installation schemes mixing wiring methods such as Division 1 and Division 2 (Zones 0, 1, 2). However, new concepts such as the High-Power Intrinsically-Safe Trunk allow for the use of fieldbus in hazardous areas without complex installation. This white paper reviews the different methods of fieldbus installation in hazardous areas and breaks down the advantages and drawbacks of each.

Installing Fieldbus White Paper
Most engineers understand the many benefits of using fieldbus technology in a variety of settings. However, installing fieldbus can be tricky for engineers with limited experience using the technology, especially since there are additional considerations above and beyond traditional 4-20mA projects. This white paper walks you through the unique challenges posed by fieldbus installations, including power supplies, device couplers and cabling.
Introduction to Fieldbus
Fieldbus technology can seem complex and challenging to someone with limited experience work with it, but the truth is that it’s an established technology that is easy to grasp and has many benefits within the process control industry. This white paper serves as a primer to the two basic fieldbuses used in the industry: PROFIBUS PA and FOUNDATION fieldbus™ H1.
IPX Approved for Natural Gas
Stations and pipelines used in the natural gas production and transportation industries require pneumatic control valve actuators in order to function. Unfortunately, this equipment is often in remote areas, where the demand for pneumatic air is often not great enough to justify installing an on-site air compressor. Current-to-Pressure (I/P) transmitters can solve this problem, but “off the shelf” solutions typically aren’t approved or designed for use in the natural gas industry. This white paper shows how the IPX2
Current-to-Pressure transmitter from Moore Industries provides an I/P solution specifically approved for the natural gas industry.
Logic Solver for Tank Overfill Protection
When a storage facility’s tank level rises above safe limits, a logic solver that is part of a Safety Instrumented System (SIS) initiates final elements to restore the process to a safe state. This can include shutting off input feeds to the tank by isolating the pump and closing the input valve. This white paper explores the possibilities available to SIS designers of tank overfill protection systems when using a logic solver. It includes examples of system topographies and their associated Safety Integrity Level (SIL) calculations.
Logic Solver for Overpressure Protection
A high integrity pressure protection system (HIPPS) is a specific type of Safety Instrumented System (SIS) that acts as a barrier between high and low pressure parts of an installation without the need to release fluid into the environment or otherwise contaminate it. Within this SIS, the logic solver initiates the final elements that restore the process back to a safe state. This white paper explores the possibilities available to SIS designers of tank overpressure protection systems when using a logic solver. It includes examples of system topographies and their associated Safety Integrity Level (SIL) calculations.
Moore Industries’ Digital and Wireless Technology Reduces Legwork at Pulp and Paper Site
New state regulations required a paper and pulp manufacturer to monitor daily effluent water rates at a remotely-located pond. This process was automated by using a HART radar level transmitter. Digital and wireless technology from Moore Industries let them send the necessary information to a HMI (Human Machine Interface) and a historical collection system thus automating an inefficient and expensive manual collection process.
Next-Generation Fieldbus Device Couplers Simplify Upgrade at Chemical Plant
Choosing the right device coupler technology was critical for Ashland Inc. in upgrading the fieldbus installation at their world-class 1,4-butanediol plant in Lima, Ohio; according to site process control specialist John Rezabek, device couplers “touch every valve in the plant.” They needed a coupler design that would incorporate short circuit protection and provide non-incendive spurs if existing disconnect switches were removed. This white paper shows how selecting the “fourth-generation” MooreHawke TRUNKGUARD Series 200 (TG200) device couplers with their unique end-of-line-sensing auto termination and “fold-back” short circuit protection allowed Ashland to solve this problem.

Safety Instrumented Systems: The “Logic” of Single Loop Logic Solvers
As companies become more aware of the risks associated with their operations due to catastrophic events, they understand the importance of complying with national and worldwide safety standards such as ANSI/ISA 84 and IEC 61508/61511. A key element to compliance and safety are Single Loop Logic Solvers, which work within a Safety Instrument System to monitor variables such as temperature, pressure, level, flow, position or status. They can provide a warning, on/off control or emergency shutdown if readings exceed a specified level. This white paper highlights safety alarm trips from Moore Industries and how they can help provide your plant with a valuable asset in complying with important safety standards and preventing potential devastating accidents from occurring in case of an emergency.

Why Use Temperature Transmitters Instead of Direct Wiring?
Temperature transmitters are quickly overtaking direct wiring as the measurement method of choice in the process control industry. Cost considerations are no longer a primary concern when choosing between these two methods of measuring temperature. So which one is the right choice for your needs? This white paper breaks down the advantages and considerations to keep in mind when thinking about using temperature transmitters rather than direct wiring.
Industrial facilities are increasing turning to wireless technology to replace miles of cabling connecting their control room to components in their network. Wireless technology is often more cost-effective than cabling and helps extend the reach of a network to an almost limitless range. This white paper discusses the advantages of using wireless technology such as the WNM Wireless Network Module as part of a distributed I/O network solution.
