Resistance Temperature Detector (RTD)

Resistance Temperature Detector (RTD)

RTD stands for Resistance Temperature Detector. RTDs are sometimes referred to generally as resistance thermometers.  An RTD is a temperature sensor which measures temperature using the principle that the resistance of a metal changes with temperature. In practice, an electrical current is transmitted through a piece of metal (the RTD element or resistor) located in proximity to the area where temperature is to be measured. The resistance value of the RTD element is then measured by an instrument. This resistance value is then correlated to temperature based upon the known resistance characteristics of the RTD element.  We manufacture 2, 3 or 4 wire RTDs. Pt-100, Pt-1000 are the common types.
