The UV flame detector is a professional industrial flame monitoring device for safety protection of combustion systems. It captures ultraviolet radiation generated by fuel combustion in real time, and implements flame detection, flame loss alarm and safety interlock protection. Equipped with high-sensitivity UV photoelectric sensing technology, it only responds to the specific ultraviolet wavelength of flame, and resists interference from visible light, high-temperature furnace radiation and ambient light. Featuring integrated structure, high temperature resistance and rapid response, it matches ground flares, TO/RTO thermal oxidizers, waste incinerators and industrial burners, delivering reliable flame monitoring for industrial combustion equipment.
• Strong anti-interference performance: Only sensitive to 185-260 nm ultraviolet band from flame. Free from disturbance of strong ambient light, high-temperature infrared radiation and light reflection, avoiding false detection and false alarms.
• Millisecond ultra-fast response: Rapidly judge flame ignition, extinguishment and abnormal fluctuation, feed flame status back to control system instantly for timely safety interlock and fuel cut-off.
• High temperature resistant & sturdy construction: Sealed aluminum alloy housing, dustproof, waterproof and anti-EMI. With air cooling port to adapt high-temperature furnace and flare site for long-time stable operation.
• High detection precision: Accurately identify valid UV flame signals and filter interference signals, monitor weak flame, unstable combustion and sudden flameout.
• Simple installation & low maintenance: Compact integrated design, easy commissioning. Continuous long-run operation with minimal daily maintenance, lowering operating cost.
The detector adopts high-precision UV phototube, which only senses characteristic ultraviolet rays generated by fuel combustion. During normal combustion, the flame emits UV light in 185-260nm range. The phototube receives UV radiation and converts optical signal into electrical signal via photoelectric effect. After internal amplification, filtering and signal processing, the detector outputs flame presence signal to the control system.
