How does a thermocouple work
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. WebThe voltage created by a thermocouple is extremely small and is measured in terms of millivolts (one millivolt is equal to one thousandth of a volt). In fact, the human body creates a larger millivolt signal than a thermocouple. To establish a means to measure temperature with thermocouples, a standard scale of
