WebFeb 1, 2024 · A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wire’s legs are welded together at one end, creating a junction. This junction is where the temperature is measured. When the junction experiences a change in temperature, a voltage is created. 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 cystic fibrosis great strides 2022
