Baso K15FA-24 Thermocouple Snap-In Type 24 Inch

The BASO Gas Products K15FA-24 is a 24-inch snap-in type thermocouple, a vital safety component for your gas furnace or boiler, weighing around 0.11 pounds. Thermocouples differ from electrical components as they don't rely on a set voltage. Instead, they generate a small millivolt (mV) signal based on temperature differences between two joined dissimilar metals. Located in the flame path of your furnace, the K15FA-24's metals react to the heat, producing a voltage typically in the range of 20-28 mV. This millivolt signal functions as a safety switch. It's sent to the gas control valve, regulating gas flow. If the flame goes out, the thermocouple cools down rapidly, causing the voltage to drop. This decrease in voltage signals the gas control valve to shut off the gas supply, preventing potential leaks and hazards.
