Pneumatic Temperature PID Control System

What is Pneumatic Temperature PID Control System?

In order to reduce the temperature or keep it at the desired level, you must connect it to the controller via a measuring device (such as PT100) that gives digital output on the pipeline. The control device processes the digital data received from the temperature sensor and sends a signal between 4-20ma to the electro pneumatic positioner on the control valve. Thanks to this signal, the control valve moves in the throttling or opening direction.
