2 7 RTD Input Wiring
RTD connection are shown in Figure 2.6, with the compensating lead connected to RTD connection are shown in Figure 2.6, with the compensating lead connected to
terminal 9. For two-wire RTD inputs, terminals 9 and 10 should be linked. The terminal 9. For two-wire RTD inputs, terminals 9 and 10 should be linked. The
three-wire RTD offers the capability of lead resistance compensation provided that the three-wire RTD offers the capability of lead resistance compensation provided that the
three leads should be of same gauge and equal length. three leads should be of same gauge and equal length.
Two-wire RTD should be avoided, if possible, for the purpose of accuracy. A 0.4 Two-wire RTD should be avoided, if possible, for the purpose of accuracy. A 0.4
ohm lead resistance of a two-wire RTD will produce 1 degree C temperature ohm lead resistance of a two-wire RTD will produce 1 degree C temperature
