- Abstract:
The article evaluates the output of digitize thermocouple near sensing point. As the thermocouple is a popular sensor for industrial temperature measurement, its output is a voltage difference across the other ends of the wires called the cold junction which must be maintained at a known temperature. This cold junction could be warmer than the hot junction wherein the polarity of the thermocouple's output voltage simply reverses. Furthermore, the sensing tip of thermocouple must be electrically insulated for the circuit to operate accurately while assuring its operating temperature range.
