[Physics.]- Physicsa 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.
Collins Concise English Dictionary © HarperCollins Publishers:: thermocouple /ˈθɜːməʊˌkʌpəl/ n - 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
- a similar device with only one junction between two dissimilar metals or semiconductors
Etymology: 19th Century: from thermo- + couple |
