Overview Q340A thermocouples sense the pilot flame on gas-fired heating systems. The pilot flame heats the tip of the thermocouple, producing a temperature differential between it and the base to generate a small amount of DC power, measured in millivolts. Features Push-in clip, split nut, and adapter assembly for easy pilot burner installation. Male nut connector for Pilotstat safety control power units. Available in a variety of lead lengths.
