In a Resistance Temperature Detector (RTD), the injection of current is used to measure resistance, which varies with temperature. A known current is passed through the RTD, and the resulting voltage drop across it is measured. This voltage is then used to calculate the resistance of the RTD, allowing for precise temperature determination based on the RTD's calibration curve. Proper current injection is crucial to avoid self-heating, which can lead to inaccurate readings.

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.
