Technical Specifications

How Does a Cartridge Heater with Thermocouple Work?

A cartridge heater converts electrical energy into heat through an internal resistance coil. In this design, a thermocouple is embedded close to the heating element, enabling continuous temperature measurement directly inside the heater.

The built-in thermocouple sends real-time temperature data to the controller, allowing precise adjustment of the heating output. This closed-loop control improves temperature accuracy, minimizes overheating, enhances process consistency, and extends the service life of both the heater and the equipment.
