المزدوج الحراري L-750 Dt2950.7 De Dietrich JJJ005303940

The thermocouple L-750 Dt2950.7 is a safety device designed to detect the pilot flame in gas-fired heating equipment. It generates a small voltage when heated by the pilot flame, which keeps the gas valve open. If the pilot goes out, the thermocouple cools and shuts off the gas supply, preventing gas leaks. This specific model, with a length of 750 mm, is suitable for many boilers and gas burners. Replacing a faulty thermocouple is a common repair that restores safe operation. Always choose a compatible thermocouple for your burner spare parts to ensure reliable flame sensing.
