For a given thermopile with having 8 series connected J-type thermocouples. If the cold junction compensation (CJC) is used where a semiconductor thermometer is used to measure the cold junction. If the semiconductor thermometer has a sensitivity of 15 m V/°C and its reading is d its reading is 7 Answe 225 mV whereas the thermopile output voltage is 8.28mV .Answer the following: 1- Find the single thermocouple voltage: ETh mV. 2- Find a- The cold junction temperature, IC °C. b- The cold junction voltage (from the tables), C mV. 3- Find a- The hot junction voltage, EH = °C. b- The hot junction temperature (from tables), I H = °C.
