An RTD, resistance temperature detector, is a passive temperature sensing device that operates on the principle that the resistance of a metal changes as the temperature changes. The electrical current that passes through the element...
A thermistor, a shortened version of the term thermal resistor, is a passive component whose resistance changes as the temperature in a system changes. Thus they serve as an inexpensive, accurate, and dynamic method for measuring temperature...
A thermocouple is a transducer that converts thermal energy into electrical energy and is constructed by joining wires made from dissimilar metals to form a junction. Voltage is produced when the temperature at the junction changes...
