resistance thermometer
Definitions
Cars & Driving
- noun an electrical temperature sensor which, in contrast to a thermocouple, needs an external voltage supply; the actual sensing element is a resistor whose resistance is an accurate indication of temperature
Electronics
- A thermometer in which the sensing element is a resistance element, usually in the form of a wire or strip. The resistance material utilized in said element has a precisely known correlation between its resistance and increases or decreases in temperature, thus enabling accurate readings. Some resistance thermometers can provide indications ranging from below -200 °C, to above 1,000 °C.
