In The Image Above, An Rtd, Symbolized As Rpt, Is Connected With Three Wires With Each Wire Having A Resistance Of R1, R2, And R3.
L1 and l3 carry the measuring current while l2 acts only as a potential lead. Web all wiring instructions required for installation are found in the chart below: Typical rtd elements are specified with 0°c values of 50, 100, 200, 500, 1000.
