How does a thermocouple function

WebJun 16, 2024 · Artwork: The basic idea of a thermocouple: two dissimilar metals (gray curves) are joined together at their two ends. If one end of the thermocouple is placed on something hot (the hot junction) and the other end on something cold (the cold junction), a voltage (potential difference) develops. WebThe governing equation for this is: E emf = −S∆T = S (T HOT − T COLD ), where: E emf is the voltage output of the thermocouple. S is a temperature-dependent material property, known as the Seebeck coefficient (For a type K thermocouple, this is roughly 4.1 μV/°C between 0°C and 1000°C) T COLD is the Temperature of the Cold Junction.
