A thermocouple is a sensor used to measure temperature. It consists of two dissimilar metals joined collectively at one finish. When the junction of the 2 metals is heated or cooled, a voltage is generated. This voltage is proportional to the temperature distinction between the junction and the opposite finish of the thermocouple.
Thermocouples are utilized in all kinds of purposes, together with industrial processes, energy crops, and scientific analysis. They’re comparatively cheap and simple to make use of, they usually can measure temperatures over a variety.
