Working Principle

A thermocouple is a temperature sensor that uses the thermoelectric effect between two different metals to measure temperature. When the temperature changes, the thermocouple generates a voltage signal proportional to the temperature change. A millivolt input module, on the other hand, is a module that is capable of receiving millivolt signals that can be converted to digital signals for subsequent processing and display.

In the 3HNA023093-001 Thermocouple/Millivolt Input Module, a thermocouple connects one end of two different metallic materials together, and the other end is connected to a terminal on the module. When the temperature changes, the voltage signal generated by the thermocouple is received by the module and converted to a digital signal output.
