WebThe key part of the thermocouple is a probe that sits close to your oven's pilot flame. Another junction of the thermocouple rests in a cool part of your appliance where the temperature will remain consistently low no matter what. When the pilot flame is burning, it heats the probe and causes a current to flow through the thermocouple's circuit. WebMeasuring principle. When two wires of different metals or metal alloys (thermo wires) are joined together in one end (hot junction), a thermocouple is formed. The free ends of those wires form a reference point. If there is a temperature difference between hot junction T1 and reference point T2, a thermal electromotive force (mV voltage) is ...
