DESCRIPTION

 

The Phoenix 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 tar-get 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 self checking.

 

The Phoenix 85UVF/IRF is available in multiple models differentiated by preset flame failure response time (FFRT), levels of hazardous area certifications and agency approvals. Refer to Table 1 on page 3 for an overview of model numbers versus FFRT and product certifications.

The Phoenix 85UVF/IRF flame scanner is powered by 24Vdc and includes an integral 10-foot (3 meter) captive cable. An analog 4 to 20mA output of flame strength is standard.

 

 

 

Phoenix 85UVF self-checking scanners are used to detect 295 to 340 nanometers wavelength ultraviolet emissions.
   Typical Applications: Duct Burners, Industrial Gas Burners, Refinery Applications, Low NOx Burners, Waste Gas Units and Incinerators.

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.

Typical Applications: Duct Burners, Industrial Oil Burners, Refinery Applications,

Waste Oil Units and Incinerators.
