How does thermocouple work
WebThermocouples are a type of sensor used for the measurement of temperature. Thermocouples use the Seebeck effect, discovered by Thomas Johann Seebeck in the early 1800s. He was able to prove that if two dissimilar electrical conductors have a temperature differential across them, then a voltage difference is produced. How Thermocouples work
