Question

5.44 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 thermocouple is assumed to have a constant sensitivity of 43 µV/°C (Note: In 3.4, the differential amplifier should be changed to difference amplifier)

Name: 544 a differential amplifier is used with a thermocouple sensor in the way shown in figure 38 what values of r and rz would give a circuit which has an output of 10 mv for temperature differ 61917

Step 1

Given sensitivity of the thermocouple = 43 µV/°C Temperature difference = 100°C Output voltage = Sensitivity x Temperature difference Output voltage = 43 µV/°C x 100°C = 4300 µV = 4.3 mV Show more…
