During calibration, an Iron/Constantan thermocouple emits a voltage of 1.02 mV at 20°C and 27.39 mv at 500°C. The reference temperature is to be set to emit a zero voltage at 0°C. Assume the transfer function is a linear relationship between 0°C and 500°C. Determine: the transfer function of the thermocouple and (V = mT ) the temperature corresponding to a voltage output of 21.5 mV. (T = V/m)
