Jun 03, 2021 Thermocouple
The thermocouple is a temperature measuring device. It uses for measuring the temperature at one particular point. In other words, it is a type of sensor used for measuring the temperature in the form of an electric current or the EMF. The thermocouple consists of two wires of different metals which are welded together at the ends. The welded portion was creating the junction where the temperature is used to be measured. The variation in temperature of the wire induces the voltages.
Thermocouples are known for their versatility as temperature sensors therefore commonly used on a wide range of applications - from an industrial usage thermocouple to a regular thermocouple found on utilities and regular appliances. Due to their wide range of models and technical specifications, it is extremely important to understand its basic structure, how it works, its ranges to better determine what is the right type and material of thermocouple for your application.
When two wires composed of dissimilar metals are joined at both ends and one of the ends is heated, there is a continuous current that flows in the thermoelectric circuit.
If this circuit is broken at the centre, the net open circuit voltage (the Seebeck voltage) is a function of the junction temperature and the composition of the two metals. This means that when the junction of the two metals is heated or cooled a voltage is produced that can be correlated back to the temperature.
