BASO Gas Products K15DA-36 36" Thermocouple Screw-In

The BASO Gas Products K15DA-36 is a 36-inch screw-in type thermocouple, a vital safety component in your gas furnace or boiler, weighing around 0.15 pounds. Thermocouples function differently from electrical components and don't rely on a specific voltage. Instead, they generate a small millivolt (mV) signal based on temperature variations between two dissimilar metals. Installed in the flame path of your furnace, the K15DA-36 uses these metals to produce a voltage typically ranging from 20-28 mV. This millivolt signal acts as a safety switch, communicating with the gas control valve to regulate gas flow. If the flame goes out, the thermocouple cools rapidly, causing the voltage to drop. This voltage decrease signals the gas control valve to shut off the gas supply, preventing potential leaks and hazards.
