a device for measuring temperature consisting of a pair of wires of different metals or semiconductors joined at both ends. One junction is at the temperature to be measured, the second at a fixed temperature. The electromotive force generated depends upon the temperature difference
2.
a similar device with only one junction between two dissimilar metals or semiconductors
Word origin
C19: from thermo- + couple
thermocouple in American English
(ˈθɜrmoʊˌkʌpəl; ˈθɜrməˌkʌpəl)
noun
a pair of dissimilar conductors joined at two points to form a closed circuit so as to produce a thermoelectric current when the junctions are at different temperatures: used in temperature measurements
: also called thermoelectric couple

A thermocouple is a temperature sensor formed by the junction of two different metals, producing a voltage proportional to the difference in temperature between the hot junction and the cold junction.
A resistor may act as a thermocouple, producing a small DC voltage differential across it due to the thermoelectric effectif its ends are at somewhat different temperatures.
There are several types of thermocouples, constructed from different metals and with differing temperature ranges and accuracies.
