Temperature AGRON 901: Page 1 RTD ( resistance Temperature Detector) Highlighted Sensor: 100 ohm PRT, DIN 43760, = , ( , Omega TFD or 1PT100FR828) General Principles of Operation and Theory A resistance Temperature Detector (RTD) is a type of sensor element that has a Temperature -dependent electrical resistance . The resistance of a RTD increases with Temperature in a linear manner over the terrestrial Temperature range ( , -50 to 100C). RTDs are made from metals or mixtures of metals, with platinum being the most common.
The most common RTD is the 100 ohm PRT (Ro=100 ohms) made from platinum conforming to the DIN 43760 standard (α of 0.00385 ohm/ohm-C). An RTD of this type should always be chosen if
