thermocouple

 [ther´mo-kup″'l]
a pair of dissimilar electric conductors so joined that with the application of heat an electromotive force is established; used for measuring small temperature differences.

ther·mo·cou·ple

(ther'mō-kŭp'ĕl),
A device for measuring slight changes in temperature, consisting of two wires of different metals, one wire being kept at a certain low temperature, the other in the tissue or other material whose temperature is to be measured; a thermoelectric current is set up that is measured by a potentiometer.
Synonym(s): thermojunction

thermocouple

[thur′məkup′əl]
Etymology: Gk, thermē + Fr, couple, pair
a temperature-measuring device that relies on the production of a temperature-dependent voltage at the junction of two dissimilar metals.

ther·mo·cou·ple

(thĕr'mō-kŭp'ĕl)
A device for measuring slight changes in temperature, consisting of two wires of different metals, one wire being kept at a certain low temperature, the other in the tissue or other material with a temperature to be measured; a thermoelectric current setup is measured by a potentiometer.

ther·mo·cou·ple

(thĕr'mō-kŭp'ĕl)
A device for measuring slight changes in temperature, consisting of two wires of different metals, one wire being kept at a given low temperature, the other in the tissue or other material with a temperature to be measured; a thermoelectric current setup is measured by a potentiometer.

thermocouple,

n the joining of two dissimilar metals. The unequal thermal expansion of the two metals is used to indicate temperature changes.
