A resistive temperature sensor Rv (calibration curve shown below) is used to measure the temperature of a process using Wheatstone bridge (Fig. 1). When the bridge is balanced, EO = OV. Then the Ry is inserted into a process whose temperature is 100C. Assume Ei = 10V, R1 = R2 = R3 = 4k12. 1. At which temperature the bridge is balanced? How much is EO at balanced mode? 2. Find the bridge output voltage E, a 3-significant figure voltmeter would show, after Rv insertion into the process. 3. Mention possible sources of errors in the configuration of Fig. 4. Justify why it is not necessary here to use the 3-wire bridge configuration. Assume the resistance of lead wires used to insert the sensor into the process is around 512. R4. RTD/
