Ultraviolet (UV) Flame Detector & Optical Flame Sensor

About this part

Optical ultraviolet (UV) flame detector designed to monitor gas, oil, and dual-fuel industrial burner flames. Operating in the 190 nm to 270 nm ultraviolet spectrum, it accurately detects burner flame radiation while remaining completely blind to glowing refractory bricks and ambient daylight, ensuring instantaneous fuel shutoff in case of flame failure.

Key features

• Selective UV spectral tube sensitive exclusively to combustion flame radiation
• Unaffected by background chamber refractory glow or interior light
• Rugged cast aluminum industrial housing with integrated cooling airflow connection
• Quick-mount clamping flange with adjustable viewing angle
• Compatible with major industrial burner sequence controllers and safety relays

Typical applications and wear

Industrial package boilers, gas burners, heavy oil burners, and multi-fuel furnaces. Wear results from UV photocell tube degradation and lens soot fouling.

Compliance

Supports burner flame-failure protection; detector compatibility and required certification must be confirmed for the burner-management system and installation.
