Beckett 7135U Cad Cell Kit for Oil Burner Primary Controls

The Beckett 7135U Cad Cell Kit is a replacement flame detection assembly designed for oil-fired heating systems. This kit provides the critical flame-sensing component that monitors burner ignition and flame presence during operation.

Key Features:

• Cadmium sulfide (CadS) photocell sensor for reliable flame detection
• Compatible with Beckett oil burner primary controls
• Pre-wired assembly for simplified installation
• Includes mounting hardware and ceramic holder
• Detects ultraviolet light emitted by oil flames

The cad cell works by changing electrical resistance when exposed to flame light, signaling the control system that ignition has occurred. When flame is lost, the cad cell triggers the safety lockout to shut down the burner. This kit is essential for maintaining safe and efficient operation of residential and light commercial oil heating equipment.
