The next best thing you need to know about digital temperature controllers


If you all are wondering about what exactly a digital temperature controller is, let me tell you. It’s an electronic control system that is a useful tool for maintaining a stable temperature range overtime. Here the controller is responsible for reading the input temperature with the help of resistive thermal or thermocouple devices and then it’s compared to the levels that are usually set by the set point.

The digital temperature controller manufacturer has designed it in a manner that it accepts a wide range of temperature inputs and keep your process temperature exactly where it’s needed by being extremely efficient.

Altogether there are three types of temperature controllers, just one type is used to control the process and this varies from application to application.

On/off temperature controller: It’s the simplest among all other types of control devices. There is no middle state, either the output is on or off. This only switches the output whenever the temperature is crossed through the set point. When it comes to the heating control process, if the temperature is below the set point, the output is on whereas if the temperature is above the set point, the output is off.

Proportional control: This is designed for the elimination of cycling that is associated with on-off control. A proportional controller helps in decreasing the average power supplied to the heater whenever the temperature starts approaching the set point. The result is a stable temperature. The proportioning action is accomplished by turning the output on and off for short time duration. The entire proportioning process takes place within a proportional band.

PID control: This is combined with proportional control along with two additional adjustments which help in compensating and changing the unit within the system.

For the interchangeability between temperature controllers, most of the digital temperature controllers are designed to standardized DIN sizes.
