(a) An instrumentation system shown in Figure Q3 (a-i) has a Nickel resistor detector device (RTD) sensor with the characteristics shown Figure Q3 (a-ii). The three wires bridge has R1= 200 Q, R2= 500 Q, and R3= 650 Q. The amplifier has a gain of 17.2, and the battery voltage is VB=1.2v. (i) Calculate the amplifier output voltage Vo when the boiler temperature is 150 °C. (ii) Explain the RTD principle of operation.
