 A differential amplifier is used with a thermocouple sensor in the way shown in Figure 3.8. What values of R1 and R2 would give a circuit which has an output of 10 mV for a temperature difference between the thermocouple junctions of 100°C with a copper constantan thermocouple if the thermo couple is assumed to have a constant sensitivity of 43 uV/oC?
