Baltur Photocell 18209023

The Baltur Photocell 18209023 is a flame sensor (photocell) designed for use in Baltur burners. It is identified by type designations 5030048 and FC13. This optical detector responds to visible or near-infrared light emitted by a flame, making it suitable for luminous flames typical of oil-fired or industrial burners. The sensor must have a direct line of sight to the flame to operate correctly.

When selecting a replacement photocell of this type, key parameters to match include spectral range (must correspond to the burner's flame color), response time (must be within the burner control's safety time), cable length and connector type, and mounting sleeve diameter. The sensor is typically installed in a sight tube or mounting flange that allows it to view the flame without overheating. Always verify compatibility with the burner control box, as electrical characteristics (e.g., output voltage, dark resistance) must match the original.

Common failure modes for photocells of this kind include a contaminated or fogged lens, an aged cell that no longer generates a strong signal, or a cracked sheath. When the sensor fails, the burner control may not detect flame within the allotted safety time, causing a lockout that requires manual reset. Regular cleaning of the sight glass and periodic signal checks can help prevent such failures.
