thermometer that measures temperature by changes in the resistance of a spiral of platinum wire

a temperature-measuring instrument consisting of a sensor (an electrical circuit element whose resistance varies with

An electrical-type thermometer that utilzes a thermal element consisting of a material whose electrical resistance varies with temperature. A thermistor is a variety of resistance therometer commonly used onboard radiosondes.

A type of electrical thermometer in which the thermal element is a substance whose electrical resistance varies with the temperature. Such thermometers can be made with very short time constants and are capable of highly accurate measurements.

Resistance thermometers, also called resistance temperature detectors (RTDs), are temperature sensors that exploit the predictable change in electrical resistance of some materials with changing temperature. As they are almost invariably made of platinum, they are often called platinum resistance thermometers (PRTs). They are slowly replacing the use of thermocouples in many industrial applications below 600 Â°C.
