WebDec 14, 2024 · What is a Thermocouple? A thermocouple is a sensor for temperature measurement. This sensor has two different metal wires, welded at one part and connected to a particular device at the other section. They can present measurement in a broad range of temperatures when configured appropriately. 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
