Manufacturer:
The Adcraft 21424 Thermopile is a vital part that uses heat from a flame to create an electrical voltage that can be detected, enabling it to read the temperature variation. It has two leads and generates between 250 and 750 millivolts that are used to operate gas safety and control systems. This thermopile is 36" long and is intended to be installed in burners, ovens, or other gas-fired appliances so that it can be exposed to the heat source, but the control circuitry can be connected. Its size is small enough to be integrated without causing interference with the other components.
