A J-type thermocouple has an output voltage Vθ = (13650 + 50 θx) μV, where θx is the junction temperature in Celsius (°C). The thermocouple is used with reference junction compensation, as shown in the figure. The Instrumentation amplifier used has a gain G = 20. If θRef is 1 °C, for an input θx of 100 °C, the output Vo of the instrumentation amplifier in millivolt is |
A. | 98 mV |
B. | 99 mV |
C. | 100 mV |
D. | 101 mV |
Answer» C. 100 mV | |
