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. It does not produce an output on its own. External electronic devices are used to measure the resistance of the sensor by passing a small electrical current through the sensor to generate a voltage. Typically 1 mA or less measuring current, 5 mA maximum without the risk of self-heating.

The term RTD stands for Resistance Temperature Detector. This sensor is also known as Resistance thermometer. This sensor is used to measure the temperature.
Usually, they are available as a length of fine wire made of platinum nickel or copper, wrapped around a ceramic or glass core. This sensor makes use of the temperature/resistance relationship of the wire to measure the temperature.
RTD sensor is used in automotive to measure the engine temperature, an oil level sensor, intake air temperature sensors. In communication and instrumentation for sensing the over the temperature of amplifiers, transistor gain stabilizers, etc…
RTD is used in power electronics, computer, consumer electronics, food handling and processing, industrial electronics, medical electronics, military, and aerospace.
