WebSep 19, 2024 · A thermocouple consists of two wires made of different electrical conductors that are connected together at one end (the “hot” end), that is the end you want to use to measure the temperature with. WebThe 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. crystal nomination charms
