Kromschroder UV photocell 74960684

The Kromschroder UV photocell 74960684 is a flame-sensing component for the UVC1 flame detector. It uses a UV tube to detect ultraviolet radiation from a flame in the spectral range of 190-270 nm. This self-checking sensor component has an operating life of 10,000 hours and a recommended replacement interval of 1 year. It comes with a mounting bracket for installation. This item is of original German quality.

Parts of this type are selected by the required sensitivity range, spectral response, electrical connection, and compatibility with the burner control's signal input. The mounting position must provide a clear line of sight to the flame without interference from hot combustion gas. Ensure the lens is clean and undamaged, and that the cable or connector matches the existing wiring.

A failing UV photocell may cause nuisance lockouts or delayed flame detection. This can result in false alarms or emergency shutdowns of the burner system. Check the photocell for damage or contamination, and verify its operation within the specified safety time.
