Solving Reactor Water Drum Level Problems

Jim Cahill

Mark Brewer Senior Consultant Author: Mark Brewer I was asked by the engineers at a chemical manufacturing site here in the United Kingdom if I could have a quick look at a level control problem in a reactor coolant water drum. They have 2 very large reactors that generate a lot of waste heat that is removed from the reactors by generating steam in cooling coils. The two reactors share a single water drum that…

Update – Providing 24VDC to Field Devices

Terry Blevins

In a blog posted late last month I addressed how to provide a 24VDC source of power to a three wire field device. In the past I have used a 24VDC High Side Discrete output to provide 24VDC to these types of devices. This solution can be implemented in most DCS and PLC systems. If … Continue reading » Read the full text.

Control Loop Foundation Reprint

Terry Blevins

A book goes through many reviews and edits before it can be published. Still, it is very difficult for the authors and reviewers to catch all the typo’s in the original text and those that are introduced during the type setting process (formatting for publication). ISA recently notified me that the book that Mark Nixon … Continue reading » Read the full text.

New Solutions providing 24VDC to 3-wire Analog and Discrete Field Devices available soon

Klaus Erni

In the past, 3-wire Analog (HART based) and 3-wire Discrete Field Devices were not directly connectable to an I/O Card nor to a CHARM Solution. With the help of the 24VDC Power CHARM, 3-wire Analog Field Devices like a Gas Detectors, can now be connected directly to a CHARM Solution by getting the Power from the 24 VDC Power CHARM, while the mA Loop is wired back to the AI 4-20mA HART CHARM. The 24VDC Power CHARM does…

Providing 24VDC to Field Devices

Terry Blevins

Some field devices such as an inductive proximity switch may be designed as three wire devices that require a 24VDC source of power. In such cases it is possible to tap into the 24 volt bulk power supply in the rack room and run twisted pair to the device. However, to protect against a short … Continue reading » Read the full text.

DeltaV V12 Alarm Descriptions enable more descriptive alarm information

Kim Van Camp

Typically a control module, as defined by the S88 standard, would contain process information associated with a single process signal or control loop. In this case, the module’s description and a standard alarm type (High, High-High, etc.) will generally provide an acceptable level of detail in an alarm list as seen below; identifying the process signal and what is abnormal about it. While this is highly adequate…

Wireless Throttling Valve Power Consumption

Terry Blevins

Something that all manufactures of wireless throttling valves must be concerned with in their design is battery power consumption. In a control application using a wireless throttling valve much of the power available to the actuator is used to track changes in target valve position. To minimize battery power consumption, the number of changes made … Continue reading » Read the full text.
