Self-regulating systems with feedback loops, i.e., the routing back of the output of a system to its input, have existed since antiquity and have since become an integral part of modern technology.

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 ...

CS series process control modules enable PID loop control of any process without using a PLC. A variety of modules are available for temperature, flow, or pressure control. Single- and dual-loop ...
