Temperature Controller

A Temperature Controller is an essential instrument used in the electrical control panels of boilers and industrial heaters to monitor, regulate, and maintain the process temperature within the desired range. It ensures safe and efficient operation by automatically controlling the heating elements, burners, or circulation systems based on real-time temperature feedback. The controller receives input signals from temperature sensors such as RTDs or Thermocouples , processes the data, and provides output to actuators like contactors, relays, or solid-state devices.

In boiler and heater applications, the temperature controller plays a critical role in process safety, energy efficiency, and equipment protection , preventing overheating, thermal stresses, and potential breakdowns. It can be configured for ON/OFF, PID, or proportional control modes , ensuring precise temperature regulation according to process requirements.

Controls temperature of steam, hot water, and thermal oil heaters .

Prevents overheating of heating coils, elements, and process lines .

Provides reliable safety interlocks in boiler electrical panels.
