An RTD (resistance temperature detector) is a temperature sensor that operates on the measurement principle that a material’s electrical resistance changes with temperature. The relationship between ...

Resistance thermometer: A type of electrical thermometer in which the thermal element is a substance whose electrical resistance varies with the temperature. Such thermometers can provide highly ...

A thin-film metallic resistor with a temperature-dependent resistance placed directly above a high-Q microcavity acts as an on-chip resistance thermometer. Integrated photonics has become a ...
