Question { BARC, 18041 }

why used three wire in RTD.


Answer

the RTD is
installed some distance away from the transmitter. Since
the connecting
wires are long, resistance of the wires changes as ambient
temperature
fluctuates. The variations in wire resistance would
introduce an error in the
transmitter. To eliminate this problem, a three-wire RTD is
used
