Temperature Controllers

A temperature controller, as the name implies, is a device used to control and monitor temperature. The controller takes input from a temperature sensor, such as a thermocouple, and compares the temperature measurement to the desired set temperature which will then provide the output (such a relay, triac or solid state relay) to a heater or fan.

Types of Temperature Controller

PID Temperature Controller - an on/off process controller that uses a mathematical formula to calculate the difference between the desired temperature setpoint and current process temperature to ensure the process temperature remains as close to the setpoint as possible. PID controllers are effective at dealing with process disturbances that can have an impact on the quality of the product that is being measured.

On-Off Temperature Controller - On-off temperature controllers (also called signallers), are simple temperature control devices. The optimal temperature is pre-set and when it's exceeded the output switches off. When the temperature falls below the optimal pre-set, the output switches on.

Proportional Temperature Controller - Able to increase or throttle back power as required, in a ratio that matches the differential between the current process temperature and the desired temperature range, this proportional control usually takes place only within a defined range of temperatures at either side of the setpoint and is designed to eliminate the cycling associated with an on-off controller.

Peltier Module Controller - Peltier module controllers are temperature controllers designed for reversible cooling and heating control of thermoelectric assemblies, depending on the current direction. They offer a fast and compact temperature control solutions and are ideal for applications that need precise and accurate temperature control.
