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 ...

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 ...

PID loops are a central component of modulating boiler control systems with applications ranging from basic steam header pressure control to cascading 3-element drum level control. A modern ...

Manual pressure management in a closed-loop mud circulating system enhances safety and efficiency of drilling and completion operations. This is the second of a four-part series of articles on the ...

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 ...

Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...

According to process control experts, a detailed and specific set of control valve requirements is more than necessary when it comes to good control loop performance. Feb. 21, 2025 Control valve ...

Pneumatic furnace damper drives may be more common, but electro-hydraulic actuators provide several advantages to the more traditional control scheme. One fossil-fired plant in Taiwan achieved more ...

Feedback-control schemes for linear systems have been around since at least the 17 th century, regulating pressure and distance between millstones and then, famously, to control James Watt’s steam ...
