Resideo Q340A Q340A1108/U Thermocouple, 1400 deg F Hot Junction, 780 deg F Cold Junction
The Q340A thermocouples sense the pilot flame on standing pilot gas fired heating systems. The pilot flame heats the tip of the thermocouple, producing a temperature differential between it and the base to generate 30 mV.
