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 â„¦ RTD with Î± = 0.00385, and all wire resistances to be equal to each other.

**Answer :**

V_{RTD} = 88.2 mV Â Â Â Â Â Â Â Â Â Â { V_{wire} = 0.5 mV (each current-carrying conductor) }

R_{RTD} = 215.12 â„¦

T = 309 degrees Celsius (from table)

T = 299.02 degrees Celsius (from formula)
