Thermocouples

[thur-muh-kuhp-uhl]

ther·mo·cou·ple

[thur-muh-kuhp-uhl]
noun Physics.
a device that consists of the junction of two dissimilar metallic conductors, as copper and iron, in which an electromotive force is induced when the conductors are maintained at different temperatures, the force being related to the temperature difference: used to determine the temperature of a third substance by connecting it to the junction of the metals and measuring the electromotive force produced.
Also called thermoelectric couple, thermoelectric thermometer.


Origin:
1885–90; thermo- + couple

Science Dictionary
thermocouple   (thûr'mə-kŭp'əl)  Pronunciation Key 
A thermoelectric device used to make accurate measurements of temperatures, especially high temperatures. It consists of a circuit having two wires of different metals or metal alloys welded together. A temperature gradient across the junction of the wires gives rise to an electric potential by the Seebeck effect. This potential varies with the strength of the temperature gradient and can be measured by a voltmeter. Thermocouples can also be used to generate small amounts of electricity for powering other devices.
