A temperature sensor is used in a Wheatstone bridge as shown below to measure temperature from 100°C to 400°C. The sensor has a resistance temperature relationship of aRT = Ro (a + T) (where T in "C). It is known that R100°c=120N and R400rc =180N. Given that a 30.3 V voltage supply Vs is available and R1= R2=1000. If R4 (in 2) is chosen such that the bridge has.an output range of O-3V, find the nonlinearity (in %) of the bridge at 140°C as a percentage of the full scale. (Answers must match to 4 decimal places.) R2 RA Temp. sensor

Question
A temperature sensor is used in a Wheatstone bridge as shown below to measure temperature from 100°C to 400°C. The sensor has a resistance temperature relationship of aRT = Ro (a + T) (where T in °C). It is known that R100°c=120n and R400°c =1800. Given that a 30.3 V voltage supply Vs is available and R1= R2=100N. If R4 (in 2) is chosen such that the bridge has.an output range of 0-3V, find the nonlinearity (in %) of the bridge at 140°C as a percentage of the full scale. (Answers must match to 4 decimal places.) R2 RA Temp. sensor
