Adc temperature compensation

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.
