How does a furnace thermocouple work
WebJun 16, 2024 · Artwork: The basic idea of a thermocouple: two dissimilar metals (gray curves) are joined together at their two ends. If one end of the thermocouple is placed on something hot (the hot junction) and the other end on something cold (the cold junction), a voltage (potential difference) develops. You can measure it by placing a voltmeter (V ... WebA thermocouple is a sensor that is used for measuring temperature.

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. WebThe Flame rod in your picture is not a thermocouple. The other connection in the circuit is the flame being in contact with a metal surface that acts as a ground. Most every flame rod system I have worked on puts and AC voltage on the flame rod. Depending on the system this voltage may be between 80 and 300 volts.
