WebDec 15, 2024 · The job of the thermocouple is to keep the pilot lit. It does this by sending a tiny electric current to a sensor on the gas valve signaling the valve to stay open. The thermocouple can do this because, in its probe, it contains two different metals, and a voltage is generated when one of them is heated. how healthcare works in the united statesWebThe thermocouple is what controls the supply of gas to the pilot light at all times. The thermocouple’s other end, a metal rod, gets pointed right over the flame of the pilot light. The rod reads the flame’s temperature accordingly. The temperature then gets registered by the rod, providing a small amount of voltage to keep the gas supply open. highest recorded stock market value dow jonesWebJul 19, 2024 · A thermocouple works through the thermoelectric effect i.e. the direct conversion of temperature differences to an electric voltage.
