Resistance Temperature Detector is a device which used to determine the temperature by measuring the resistance of pure electrical wire. This wire is referred to as a temperature sensor. If we want to measure temperature with high accuracy, RTD is the only one solution in industries. It has good linear characteristics over a wide range of temperature.

The advantages of platinum resistance thermometers include:

1)High accuracy

2)Low drift

3)Wide operating range

4)Suitability for precision applications.
