The FIREYE 85UVF1-1QD is an ultra-violet flame scanner engineered for critical combustion safety in industrial burners and boilers. As part of Fireye’s flagship UV scanner series, this device provides fail-safe flame monitoring for gas, oil, and multi-fuel applications. The 85UVF1-1QD features a high-sensitivity UV phototube with 100° viewing angle, detecting flame signatures within 500 milliseconds to ensure safe ignition sequences and immediate shutdown during flame failure. Its hermetically sealed stainless steel housing (NEMA 4X/IP66) withstands furnace temperatures up to 200°C while resisting corrosion in coastal or chemical environments. With integrated self-check diagnostics and automatic sensitivity compensation, the FIREYE 85UVF1-1QD maintains detection reliability despite quartz window fouling or aging phototubes. Designed for integration with Fireye MicroM and NXM series flame safeguards, this scanner meets NFPA 85/86 standards for power plants, refineries, and process heaters where combustion safety is non-negotiable.

Main Features and Advantages
Advanced UV Optics: Proprietary quartz lens with anti-fouling coating extends maintenance intervals 3x compared to conventional scanners. Phototube shielding eliminates false triggers from welding arcs or lightning.
Intelligent Diagnostics: Continuous self-monitoring detects phototube degradation or lens obstruction. Automatic gain compensation maintains sensitivity as components age.
Robust Construction: Forged 316 stainless steel housing withstands direct flame impingement. Spring-loaded purge collar prevents hot gas infiltration during burner cycling.
Simplified Calibration: Integrated alignment sight and ±30° swivel mount enable single-person commissioning. Status LEDs provide visual confirmation of flame signal strength.
Universal Compatibility: 4-20mA output interfaces with DCS/PLC systems, while SPDT relay supports direct burner management. Reverse polarity protection prevents damage during wiring errors.
Application Field
The FIREYE 85UVF1-1QD secures combustion processes where flame failure risks explosions. In power generation, it monitors tangentially-fired coal boilers through intense ash clouds. Refinery process heaters rely on its corrosion resistance to detect crude oil flames in sulfur-rich environments.
For pulp & paper recovery boilers, the scanner withstands 180°C black liquor spray while maintaining flame detection. Thermal oxidizers in chemical plants utilize its wide viewing angle to monitor complex flame patterns. Marine applications benefit from its IP66 rating when monitoring auxiliary boilers in engine rooms. Cement kilns deploy the 85UVF1-1QD where limestone dust obscures flame visibility, leveraging its automatic gain adjustment. Unlike IR scanners, the FIREYE 85UVF1-1QD reliably detects hydrogen flames in syngas applications where hydrocarbon signatures are weak.
