RTD stands for Resistance Temperature Detector. 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.

What is an RTD Sensor?

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.

Applications of RTD:

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.
