An RTD forms one arm of a Wheatstone bridge, as shown below. The RTD is used to measure a constant temperature, with the bridge operated in a balanced mode. The RTD has a resistance of 250 at a temperature of 0C and a thermal coefficient of resistance, a = 0.003925C-. The value of the variable resistance R must be set to 3702 to balance the bridge circuit. The input voltage to the bridge is 5V. R-R-1000 R-25 02 at 0C and balanced bridge conditions 8 RTD 1. Determine the temperature of the RTD. 2. If the fundamental relationship between resistances in a Wheatstone bridge and the normalized output R3 voltage is provided as, R Determine the output of the bridge circuit. EL R+R R3+R =
