A thermocouple utilizes Seebeck’s Effect to produce a voltage measuring technique discovered by Thomas Seebeck in the 1800s. Two dissimilar metals connected in a circuit with temperature junctions produce a steady electrical current according to his discovery. Thermal energy activates hot junction electrons and produces a voltage difference which pushes electrical current from hot to … Continue reading Why Thermocouple Reference Junction Compensation(CJC) is Essential for Accurate Temperature Measurement ?
