Honeywell Q340 Universal 30 mV Thermocouple

Universal 30 mV Thermocouple
Q340

Thermocouples generate a thermoelectric current that senses a 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. This temperature difference generates a small amount of DC power, measured in millivolts.

• Push-in clip, split nut, and adapter assembly for easy pilot burner installation.
• Spade or quick-connect terminals available for millivolt gas control connections.
• Male nut connector for Pilotstat™ safety control power units.
• Available in a variety of lead lengths.
