Full form of RTD

The full form of RTD is Resistance Temperature Detector. A sensor type known as an RTD has a resistance that changes with temperature and rises as the sensor’s temperature rises. Temperature and resistance have a consistent and well-established connection.

Characteristics of RTD

  • Because they are pure metals, copper, nickel, tungsten, and platinum are frequently utilized in resistance temperature detection systems. 
  • Variable resistance transducers is another name for resistive transducers or resistive sensors. 
  • Its temperature coefficient of it is positive.
  • Physical quantities including temperature, pressure, displacement, force, vibrations, and more may be measured using them.
  • The variable resistance transducer elements operate under the premise that conductor resistance is directly proportional to conductor length, inversely proportional to conductor length, and inversely proportional to conductor area.

An RTD is a passive device that is unable to generate an output on its own. It serves as a substitute for a resistance thermometer. By applying a small electrical charge to the sensor to produce a voltage, external electronic equipment may measure the sensor’s resistance. Typically, measuring currents between 1 and 5mA is the highest possible without the risk of self-heating.
