A 3 wire sensor typically is color coded with one brown wire one blue wire and one black wire. The graph below shows the temperature error from leadwire of various sizes and lengths for a 3 lead 100 ohm platinum rtd at 100c. There is a lead resistance in each arm of the bridge so that the resistance is cancelled out so long as the two lead resistances are accurately the same. 800 x 600 px source.
