What is process controller?

Process control is all about using the best available control techniques for machinery and processing control. 

 Process controllers maintain the output of process variables such as temperature, pressure, flow, or level within a pre-set range. They use feedback from sensors to identify any deviation from a setpoint and automatically adjust output until parameters are back within range.

Automatic process control in continuous production processes is a combination of control engineering and chemical engineering disciplines that uses industrial control systems to achieve a production level of consistency

The purpose of process control:-

To stop any unwanted variation in a production process, a control loop monitors the process regularly to check it's performing as it should. 

This is usually done by a sensor that measures a particular property like temperature. 

A transmitter converts the sensor's output into a signal which is sent to a controller.
