Électrode d'ionisation - 7.8x40 - De Dietrich JJX000529945

The ionisation electrode -7.8x40- is a flame sensing rod used in burners to detect the presence of a flame via ionisation current. This electrode is typically installed in the burner head and is exposed to the flame, where it generates a small electrical signal that confirms combustion. It is a critical safety component in gas burners and other heating equipment. The -7.8x40- designation indicates its dimensions, making it suitable for specific burner models. For boiler maintenance and repair, replacing a worn ionisation electrode is essential for reliable flame detection and safe operation.
