Thermocouple Wikipedia

A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. A thermocouple produces a temperaturedependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature. Thermocouples are widely used as temperature sensors. Commercial thermocouples are inexpensive, interchangeable, are …

A Basic Guide to Thermocouple Measurements

Any connection between two different metals creates a thermocouple junction. Connections from the thermocouple to the ADC should be simple and symmetric to avoid unintentional thermocouple junctions. These additional junctions cause measurement errors. As the thermocouple signal connects to the ADC integrated circuit, each step along the path can encounter several additional thermocouples ...
