Fireye 85UVF1A-1QD Scanner
The Fireye 85UVF1A-1QD is a micro-processor based Phoenix II ultraviolet flame scanner designed for high-integrity industrial burner management. As the direct replacement for the 85UVF1-1QDK3, this integrated unit combines a solid-state UV sensor and an internal flame relay, eliminating the need for external flame amplifiers. It operates on 24 Vdc and features a selectable Flame Failure Response Time (FFRT), making it a versatile choice for low NOx burners, duct burners, and refinery applications. The 85UVF1A-1QD provides an optically isolated 4-20mA analog output for real-time monitoring of flame signal strength, alongside a dedicated fault relay (SPST N.C.) for systemic safety. Housed in a NEMA 4X / IP66 rated cast aluminum enclosure, it withstands internal temperatures up to 180??F while maintaining precision. For consistent operation in high-dust environments, ensure clean, dry cooling air is supplied at 4 to 15 SCFM via the 3/8" NPT connection on the 60-2919-1 mounting flange.
Key Benefits for Industrial Combustion
- Direct Replacement: Seamlessly replaces the legacy 85UVF1-1QDK3 and older captive-cable models with a modern 8-PIN quick-disconnect interface.
- Integrated Logic: Internal flame and fault relays streamline burner management system wiring by removing the requirement for remote switching modules.
- Superior Discrimination: Advanced digital signal processing allows the scanner to distinguish between actual burner flames and background furnace radiation.
- Rugged Reliability: ATEX certified and IP66 rated housing ensures performance in hazardous locations and extreme ambient temperatures.
- Flexible Sighting: Compatible with fiber optic cable assemblies for challenging sighting geometries or high-vibration mounting points.
Common Technical Questions
What is the primary difference between the 85UVF1A-1QD and the K3 variant?
The 85UVF1A-1QD is a standard ultraviolet scanner, whereas "K3" models include an optical filter that shifts sensitivity toward the 310nm to 500nm range, specifically for applications requiring different spectral responses.
Does this scanner require a separate power supply?
Yes, it requires a 24 Vdc (nominal) power source. For optimal performance and to maintain a SELV rating on the 4-20mA leads, a Fireye 60-2685-X series power supply is recommended.
Can I use my existing mounting flange when upgrading?
If you are replacing a first-generation Phoenix scanner, the mounting flange must be upgraded to the 60-2919-1 (1" NPT) or 60-2919-2 (1" BSP) to ensure proper fit and purge air flow.
