RTD stands for resistance temperature difference.There are three types of RTD i.e 2 wire,3 wire and 4 wire.A PT-100 RTD is generally used in industry to determine temperature.It`s one end sense temperature and hence due to this resistance of metal changes.This change in resistance is calculated and temperature is calculated through a formula:
R=r(1+@^t) where ^ = .03692

2 wire.3 wire nd 4 wire...rtd... 3 wire rtd is widly used....hv good accuracy...
A 3-wire RTD (Resistance Temperature Detector) works by using three wires to measure temperature through resistance changes in a metal element. Two of the wires carry current to the RTD, while the third wire is used to measure the voltage drop across the RTD element. This configuration helps to eliminate the effects of lead wire resistance, improving accuracy in temperature readings. The resistance change is then correlated to temperature using a standard calibration curve.
