Product Overview
-
Manufacturer: Fireye
-
Part Number / Model: 85UVF1A-1QD (Phoenix Series 2)
-
Component Type: Microprocessor-Based Ultraviolet (UV) Integrated Flame Scanner
-
Platform: Burner Management and Combustion Safety Systems
Key Specifications & Features
-
Detection Technology: Utilizes a solid-state ultraviolet (UV) sensor designed to detect UV emissions (specifically within the 295 to 340 nanometer wavelength range) typical of fossil fuel flames.
-
Internal Flame Relay: Features an onboard internal flame relay with automatically set ON/OFF thresholds, removing the requirement for a separate, remote flame amplifier or switch.
-
Signal Processing: Analyzes broadband modulation amplitudes (the flame “flicker”) across a wide frequency spectrum, automatically storing target flame parameters and optimizing sensor gain during setup.
-
Electrical Connection: Equipped with an 8-pin electrical quick-disconnect (QD) connector, facilitating straightforward wiring installations and maintenance.
-
Power Supply: Powered by nominal 24 VDC.
-
Outputs:
-
Standard isolated 4 to 20 mA DC analog output for real-time remote monitoring of flame signal strength.
-
SPST normally open (N.O.) flame relay and SPST normally closed (N.C.) fault relay outputs.
-
-
Self-Diagnostics: Incorporates continuous electronic self-checking and full diagnostic routines to guarantee fail-safe operation.
Industrial Deployment
-
Applications: Widely deployed across industrial boilers, commercial power plants, duct burners, refinery furnaces, low-NOx burners, waste gas incinerators, and process heating systems to ensure reliable burner supervision and emergency shutdown protection.
