BASO Gas Products K19AT-18 18" Thermocouple

The K19AT-18 Gas Products from BASO Thermocouples are safety sensors found in HVAC systems that burn natural gas, such as water heaters and furnaces. It transforms the heat from the pilot light into a low voltage, usually between 25 and 30 millivolts. A gas control valve receives this voltage signal and adjusts the gas flow according to the thermocouple's temperature reading. The gas control valve will cut off the gas supply if the pilot light goes out since the thermocouple won't detect heat and the voltage will drop as a result. This safety measure aids in averting possible explosions and gas leaks. Although the parameters you mentioned—length, weight, voltage, and resistance—give information about the thermocouple's physical properties, they are not necessary to comprehend its primary purpose.
