Fireye 85UVF1A-1QDK3 Phoenix II UV Flame Scanner with K3 Filter

The Fireye 85UVF1A-1QDK3 Phoenix Series II is a microprocessor-based ultraviolet flame scanner designed for critical industrial combustion monitoring applications. This advanced integrated flame scanner utilizes solid-state UV detection technology with an enhanced K3 optical filter that extends the spectral sensitivity range from 310 nm up to 500 nm, making it particularly effective for steel plant applications including blast furnace gas and coke oven gas burners.

Key Features:

• Selectable Flame Failure Response Time (FFRT) for customizable flame detection parameters
• K3 optical filter for extended wavelength detection (310-500 nanometers)
• Internal flame relay with automatic ON/OFF thresholds eliminates need for remote amplifier
• Microprocessor-based flame flicker detection across wide frequency range
• Full self-diagnostics and electronic self-checking capabilities
• 8-pin quick disconnect (QD) for tool-free installation and maintenance
• Standard 4-20mA analog output for continuous flame strength monitoring
• 4-button keypad with multi-LED status indicators
• Cast aluminum housing with gray polyester powder coat and IP66 rating

Specifications:

• Power Supply: 24 VDC
• Spectral Range: 310-500 nm (UV with K3 filter)
• Operating Temperature: -40°F to 150°F ambient (-40°C to 65°C)
• Scanner Weight: 5.90 lbs
• Ingress Protection: IP66 with 0.4 joule impact rating
• Certifications: FM, UL/c, CE approved

Installation Requirements:

• Requires 59-546-XX series cable for electrical connection
• Compatible with mounting flanges: 60-2692 or 60-2919 (1" NPT)
• Clean, dry purge air recommended for optimal performance

The Phoenix II scanner automatically stores target flame amplitude characteristics during setup and selects optimal sensor gain, making it ideal for duct burners, industrial gas burners, refinery applications, low NOx burners, waste gas units, and incinerators. Its self-checking design ensures reliable flame detection while reducing false alarms and unplanned shutdowns.
