What is an RTD | Understanding RTD Sensors | TE Connectivity

Understanding RTD''s. An RTD (Resistance Temperature Detector) is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases. The resistance vs temperature relationship is well known and is repeatable over time. An RTD is a passive device.


RTD SensorDefinition, Working Principle, Characteristics ...

· RTD sensor is basically a temperature sensing device in which change in resistance of the detector element is calibrated with temperature. Thus, a change in resistance directly gives the value of temperature of the system. It is used to measure the temperature of a system and also known as Resistance Thermometer.
