85UVF1A-1QD Integrated Flame Scanner with Internal Relay

The Fireye Phoenix Series 2 type 85UVF/IRF flame scanners are microprocessor based devices utilizing a
solid state flame detection sensor. The Phoenix flame scanners incorporate an internal flame relay with automatically

set ON/OFF thresholds, thereby eliminating the need for a remote flame amplifier or flame switch.
Phoenix scanners detect the amplitude of the modulations (the flame “flicker”) that occur within the targeted
flame, over a wide frequency. During the scanner setup procedure, the amplitudes of the target flame are
automatically stored by the flame scanner, together with optimum ON/OFF criteria. The appropriate sensor
gain is automatically selected. Phoenix scanners incorporate full self-diagnostics and electronic selfchecking.
The Phoenix 85UVF/IRF is available in multiple models differentiated by spectral range, levels of hazardous
area certifications and agency approvals. Refer to Table 1 on page 3 for an overview of model numbers versus
product certifications. Versions with stainless steel housings are also available.

Fireye Phoenix 85UVF self-checking scanners are used to detect 295 to 340 nanometers wavelength ultraviolet emissions. The

Fireye Phoenix 85UVF1A-1QDK3 and 85UVF1-1CEX-K3 Flame Scanners are
derivatives of the standard Phoenix product but utilizing an advanced optical filter. This filter adjusts the
optical sensitivity of the detection cell to pick up wavelengths of light from the standard 310 nm range up to
500 nm.
Typical Applications: Duct Burners, Industrial Gas Burners, Refinery Applications, Low NOx Burners, Waste
Gas Units and Incinerators. The K3 scanner is particularly suited to measure the light emissions from steel plant
applications such as burners firing blast furnace gas and coke oven gas.
Fireye Phoenix 85IRF self-checking scanners are used to detect 830 to 1100 nanometers wavelength infrared
emissions. They are suited for application to duct burners, industrial gas burners, refinery applications ignition
systems and Low NOx detection and for continuous or non-continuous burner operation.
