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.

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.
