thermocouple

A thermocouple is a device used to measure temperature by utilizing a pair of dissimilar metal wires welded at one end. The variation in temperature between the two ends of the wires generates a voltage that is proportional to the temperature difference. This voltage can be measured by a voltmeter, which then converts it into…

A thermocouple is a device used to measure temperature. It consists of two dissimilar metals that are joined together at one end. When the junction of the two metals is heated or cooled, a voltage is generated. This voltage is proportional to the temperature difference between the junction and the reference temperature. Thermocouples are used…
