WebSep 7, 2024 · This page provides a fundamental discussion of what a thermocouple is and how it works. A thermocouple is a temperature measuring device that can operate in a wide range of temperature. It is created by joining two dissimilar metal and/or semiconductor wires together. Thermocouples are inexpensive to make. WebHow does a thermocouple work? Thermocouples are based on the Seebeck effect, which says that when a pair of dissimilar metals in contact with each other at each end are subjected to changes in temperature, they create a small voltage potential. And they do this passively, i.e., they do not need to be powered by a signal conditioner.
