Concept explainers

RTD (Resistance Temperature Detector)

A resistance temperature detector is a passive electronic device or a sensor. The name itself suggests that it is related to resistance, temperature, and detection. Similarly, its resistance changes when there is a temperature change; the resistance increases when the temperature of the RTD device increases or vice-versa. It is also known as a resistance thermometer. Its working is similar to the thermocouple.
