How thermocouple works

Question

Accepted Answer

A thermocouple is a temperature sensor that works based on the principle of the Seebeck effect.

A thermocouple consists of two different metal wires joined together at one end.
When there is a temperature difference between the two junctions, it creates a voltage.
This voltage is proportional to the temperature difference and can be measured using a voltmeter.
Thermocouples are commonly used in industrial applications for temperature measurement.
For example, in a furnace, a thermocouple can be used to monitor and control the temperature.

Accepted Answer

A thermocouple is a device for measuring temperature. It comprises two dissimilar metallic wires joined together to form a junction. When the junction is heated or cooled, a small voltage is generated in the electrical circuit of the thermocouple which can be measured, and this corresponds to temperature
