The Fundamentals of Industrial Thermocouples

Industrial thermocouples are temperature sensors used to measure heat in industrial settings. They consist of two different metal wires joined together to form a junction. When the junction is exposed to a temperature gradient, it generates a voltage that is proportional to the temperature difference. This phenomenon, known as the Seebeck effect, forms the basis of thermocouple technology.

Understanding Thermoelectric Principles

The Seebeck effect, named after the German physicist Thomas Johann Seebeck, is the underlying principle behind the operation of industrial thermocouples. When two dissimilar metals are joined to form a circuit and the junctions are maintained at different temperatures, an electromotive force (EMF) is produced, creating a measurable voltage. This voltage is directly related to the temperature difference between the junction and the reference point, enabling precise temperature measurements.
