In 1821 the German scientist Thomas Seebeck (1770-1831) was experimenting with the thermal properties of certain metals. He constructed a loop of two different metals and applied heat to one of them. To his surprise a magnetic field was formed, as if a...

is a temperature-measuring device comprising two wires of different metals connected to form a circuit. If one junction of the wires is maintained at a constant temperature and the other junction subjected to a change in temperature an electrical...

An assemblage of thermo-electric sensors that are used to measure...

In electronics and in electrical engineering, thermocouples are a widely used type of temperature sensor[1] and can also be used as a means to convert thermal potential difference into electric potential difference.[2] They are cheap[3] and...

by Ken Whiteleather, Sparton Corp During the development of a medical product requiring noninvasive temperature sensing of fluid passing through 3/8-in. medical plastic tubing, the design team I was working with selected a miniature infrared optical temperature sensor. The cylindrical sensor measured...

Thermocouples By Joe Escobar How these temperature-sensing devices work Thermocouples are used in different temperature-sensing applications in turbine engines. However, despite their abundant use in aircraft systems, we are often not aware of how these seemingly simple devices actually work....
