How does thermocouple measure temperature
WebTemperature Measuring Devices Thermocouples When a pair of electrical conductors (metals) are joined together, a thermal emf is generated when the junctions are at different temperatures. This phenomenon is known as the Seebeck Such a … 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
