Determine the temperature of the RTD, given a measured voltage of 89.2 millivolts between test points C and D, and 88.7 millivolts between test points E and D:
Assume a 100 Ω RTD with α = 0.00385, and all wire resistances to be equal to each other.
Answer :
VRTD = 88.2 mV { Vwire = 0.5 mV (each current-carrying conductor) }
RRTD = 215.12 Ω
T = 309 degrees Celsius (from table)
T = 299.02 degrees Celsius (from formula)
