Platinum Resistance Thermometers (RTD, PRT, Pt100 Sensors)
What is a Resistance Thermometer?
A Platinum Resistance Thermometer, commonly referred to as RTD Sensors, PRT Sensors or Pt100 Sensors, is a type of resistance temperature sensor used for a wide variety of temperature measurement applications. Resistance thermometers work on the principle that there is a repeatable change in the resistance of the sensing element with a change in temperature. For full details on the principles and theory of resistance thermometers please click here.
There are many types of Resistance Thermometer such as Pt1000, but typically they are Pt100 (made using a Platinum element with a resistance of 100 ohms @ 0ºC and typically with a 38.5 ohm fundamental interval - change in resistance over the range 0 to 100ºC), available in a wide range of designs and constructions as shown below.
