Question

Signal Conditioning Exercises ELE 2603 27. A sensor is connected in a voltage divider configuration as R2. If the sensor has a transfer function of 0.2 0/°C. if R1 250 Q and Vs 5 V. What is the temperature of the sensor when VD 1.25 V? R1 Vs W VD R2 Answer 28. Find Vab in mV for the circuit shown when R1- 350 0, R2 500 , R3 400 Q and R4 is flow sensor with a transfer function of .35 Ohm/liter when the sensor reads 25 liter and Vcc -1V?
