Temperature controllers are instruments used to control temperature, mainly without extensive operator involvement. The temperature control system relies on the controllers to receive a signal from temperature sensors such as thermocouples or RTD as input and compare the actual temperature to the desired control temperature or set value. It will then provide an output to control the heating element.
Chordn electric, as an expert in temperature controller, has been manufactureing the temperature controllers for more than 50 years. There are three basic types of controllers: low-cost PID controllers, high-performance PID controllers and temperature control modules.
