Temperature Measurement Utilizing Platinum Resistance Sensors

Platinum resistance sensors are currently used for continuous service from -260°C to +800°C and up to 1200°C for short term use. The historical development of resistance sensors is discussed and the advantages of using platinum resistance sensors over thermocouples is described. Parameters used in the evaluation of platinum sensors and signal conditioners are enumerated. Errors encountered in temperature measuring schemes and methods to reduce these errors are summarized.
