POLARITY 3 WIRE RTD WIRING DIAGRAM
Difference between AC and DC (Current & Voltage)
Polarity: There is no polarity in AC because it fluctuates. There is fixed polarity in DC marked by Positive (+) and Negative (-) signs: Swapping Terminals or Polarity: Swapping the source terminal will not affect the circuit: Swapping the source terminal may damage the circuit. Frequency: The frequency of the alternating current is usually 50

This is usually true where the leads are no longer than a few (<3) meters for a 100 Ω RTD. 5.3.4 Four-wire RTD measurement. A better method of excitation and measurement, especially when the wire lead lengths are greater than a few meters in length, is the four-wire RTD configuration shown in Figure 5.4.
