A thermocouple is a sensor that measures temperature. It consists of two different types of metals, joined together at one end. When the junction of the two metals is heated or cooled, a voltage is created that can be correlated back to the temperature. Thermocouples are commonly used in a wide range of applications.

What is thermocouple in thermodynamics?
Thermodynamics Glossary - Thermocouple. Thermocouple. A Thermocouple is an electrical device that can be used as a thermometer. It is comprised of two metals, A, B, that form a simple circuit with two junctions, J, between the metals as shown opposite.
What are the essential components of a thermocouple instrument?
Most thermocouple installations comprise a thermocouple, extension wires, and an instrument. Extension wires basically are used to extend thermocouples to an indicator; measuring device or control instruments.14 May 2019
