Temperature Controller

Written by Jerry Ratzlaff. Posted in Temperature Instrument

A temperature controller is an instrument designed to minimize operator input or involvement. A temperature controller has an input that is connected to a temperature source such as an RTD or other type of temperature element. It has an output that connects to a control element such as a temperature control valve or a heater or fan.

The input temperature is compared against a set temperature and the controller adjusts the output device appropriately.
