A thermocouple is defined as a thermal junction that functions based on the phenomenon of the thermoelectric effect, i.e. the direct conversion of temperature differences to an electric voltage. It is an electrical device or sensor used to measure temperature.
A thermocouple can measure a wide range of temperatures. It is a simple, robust, and cost-effective temperature sensor used in various industrial applications, home, office, and commercial applications.
In 1821, German physicist Thomas Johann Seebeck found that a magnetic field is produced when two different metals are connected at one end and create a temperature difference between two ends.
He observed that due to the magnetic field the voltage is induced by the thermoelectric effect. However, this voltage is very small (in terms of mV) and depends on the type of metal used in the thermocouple.
According to the applications, different designed configurations of thermocouples include thermocouple probes, probes with connectors, infrared thermocouples, base wire thermocouples, and just thermocouple wire.
