Cell MZ-770S De Dietrich 97901209

The cell MZ-770S is a flame sensor used in various gas burner systems to detect the presence of a flame. It typically works by sensing the ultraviolet or infrared radiation from the flame and providing feedback to the burner controller. This component is critical for safety, as it ensures the gas valve remains open only when a flame is present. Replacing a faulty flame sensor is a common task in boiler maintenance and repair, and this cell is designed to be compatible with many burner models.
