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 ...

Flow controllers are electric devices that monitor and provide feedback to control flow-rate variables as part of a process control application. They can be used in conjunction with pumps, valves, ...

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 ...

The previous sections of this chapter have dealt with the tuning of controllers for self-regulating processes such as temperature and flow. Liquid-level control, however, has characteristics ...

The controller contains the “control algorithm,” or control logic equation. The most common control algorithm is called PID, which stands for Proportional (P)-Integral (I)-Derivative (D). When the ...
