A thermocouple produces an emf in mV according to the temperature difference between the sensor tip 82 and the gauge head 01 such that e = a (61 - 02) + b (812 - 022) a= 6 x10 2 and b = 8 x10. The...

Extracted text: A thermocouple produces an emf in mV according to the temperature difference between the sensor tip 82 and the gauge head 01 such that e = a (61 - 02) + b (812 - 022) a= 6 x10 2 and b = 8 x10. The sensor tip is at 22°C. The voltage output is 20mV. Calculate the temperature in guage head.
