Coblentz first studied the problem of heat production in the firefly, using a thermocouple as the measuring instrument.
The thermocouple glowed red, and electricity jumped in the copper veins, turning the metal bone into a magnet.
I've been suffering the attentions of the damnedest collection of amateur nurses who ever handled a thermocouple, for over a week.
When Frank examined the sun-powered tractor, he found that tiny platinum plates had been taken from the thermocouple units.
She fastened two wires to two other wires, adjusted the lens, and the tips of the thermocouple glowed red.
This large, squat telescope catches and concentrates on the thermocouple and the galvanometer registers the temperature.
thermocouple ther·mo·cou·ple (thûr'mə-kŭp'əl)
A thermoelectric device used to measure temperatures accurately, especially one consisting of two dissimilar metals joined so that a potential difference generated between the points of contact is a measure of the temperature difference between the points.
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.
A device for accurate measurement of temperature. A thermocouple consists of two dissimilar metals joined at two joints in a loop so that the difference in voltage can be measured. Because voltage changes in proportion to temperature, the voltage difference indicates temperature differences.
