Fireye 85UVF1A-1QDK3 UV flame detector probe
85UVF1A-1QDK3 is a Fireye Phoenix II series integrated ultraviolet flame detector probe. The 85UVF1A-1QDK3 integrates a microprocessor, ultraviolet sensor, and built-in flame relay, without the need for an external flame amplifier. Using UV spectroscopy to detect gas and fuel flames, automatically identifying the flickering characteristics of flames, and determining the presence or absence of flames; When the flame goes out, quickly output a switch interlocking signal to the combustion management BMS system, triggering fuel cut-off protection to prevent explosion accidents; Simultaneously output 4-20mA analog signal and provide feedback on flame intensity to DCS monitoring. The K3 version has explosion-proof certification, and 85UVF1A-1QDK3 is suitable for flame monitoring of hazardous area burners.

Product features
- Integrated design, built-in flame relay, eliminating external amplifier, simplifying BMS combustion safety circuit.
- Flame automatic learning function, the probe can automatically remember the characteristics of the target flame, set the gain and threshold automatically, and is easy to debug.
- Complete onboard self diagnosis, real-time monitoring of sensor and circuit faults, fault alarm output for easy maintenance and troubleshooting.
- UV detection principle, sensitive to gas and fuel flames, can distinguish background radiation from real flames.
- IP66/NEMA4X cast aluminum shell, dustproof and waterproof, suitable for harsh working conditions such as high temperature, dust, and oil mist in boilers.
- 8-pin quick plug connector, easy to disassemble and assemble, reducing on-site maintenance downtime.
- Support blowing and air cooling to protect optical lenses and prevent furnace smoke and dust from contaminating the lenses.
- It has explosion-proof certification for hazardous areas and is suitable for chemical and oil and gas combustion devices with flammable and explosive media.
