Why 4 wire RTD’s measurement accuracy is better than 2 and 3 wire RTD?

RTD Measurement: An Overview  The Requirement for Compensation Benefits of 4-Wire RTD Measurement In comparison to the 2-wire and 3-wire configurations, the 4-wire RTD measurement configuration is clearly superior, principally because lead wire resistance is completely eliminated.  With a 4 wire RTD, resistance is not used to determine the temperature. The two lead wires of …
