Description
Resistor,thermal
CAGE
98738

A thermally sensitive resistor whose primary function is to exhibit a change in electrical resistance with a change in body temperature. Item may be mounted in a probe or housing. For ballast tube type resistors, see resistor (1), current regulating. Excludes transmitter (1), temperature, electrical resistance and temperature element, resistance meteorological.
