Calculate the Temperature of 4 Wire RTD

Determine the temperature of the RTD, given V_CD = 140.5 millivolts and V_EF = 140.1 millivolts:

Assume a 1 kΩ RTD with α = 0.00385, and all wire resistances completely unknown (not assumed to be equal).

Answer :

VRTD = 140.1 mV

R_RTD = 1167.5 Ω

T = 43.5 ^oC = 110.31 ^oF (both values calculated from formula, not table)
