Plant engineers and technicians are frequently asked to tune the controller when a control loop’s process value has prolonged or significant excursions from the set point. But in many instances, no ...

Power plants–especially coal-fired boilers–pose a set of process control problems unparalleled in other industries. Rapid load ramps, continuous unit demand changes, variable fuel quality and process ...

Every plant in the process industry most likely has several control loops that do not perform well. Although there are many factors that may negatively affect control loop performance, a few of these ...

Editor’s note: This month we are pleased to have Colin Wells from Texas Instruments as our blogger. In modern industrial control systems, 4-20 mA current-loop transmitters remain one of the most ...

This reference design shows how to develop a high-performance, high-voltage 2- or 3-wire 4–20mA current-loop transmitter suitable for industrial process control and ...

In 2012, Automation World published an article looking at the decision factors faced when choosing electric or pneumatic actuators. More than a decade later, manufacturing engineers and OEMs still ...
