Process Control
Process controllers, or PID controllers, are electronic devices used to measure a process variable and make adjustments to keep that variable within a set range or at a desired setpoint. Controllers are used in industry to regulate temperature, pressure, force, flow rate and much more.

Process controllers use embedded software and a wide variety of functions to make precise adjustments using advanced feedback control. PIDs continuously take measurements from sensors and make adjustments to the final control element to maintain the desired setpoint. Alarms notify operators of any undesired measurements or results.

Most controllers also have a display, and can provide display parameters based on hardware configuration, masking irrelevant parameters if necessary. This way, operators only need to adjust the setpoint and alarm, then launch self-tune.
