For the creation of the WINDOW 141 scanner, we applied our long field experience in flame scanning. We considered the following requirements and difficulties in the field:

Discrimination problems (opposing and adjacent flames)	Independent UV and IR detection • Proven discrimination techniques • Detects IR flicker frequency up to 5000Hz
Scanner head alignment Flame behaviour	• WINDOW type scanner head for sight adjustment and visual monitoring of the sighted flame to improve discrimination

Easy set point adjustment	• Individual adjustable FFRT from 0.5 to 3.5s (± 0.5) for both IR and UV • No adjusting potentiometers: adjustments are possible only by the handheld DT (Data Terminal) • Easy and comprehensive commissioning and adjusting procedures through Data Terminal
Application for various fuels	• Dual UV/IR detection with independent relay outputs
Comprehensive flame strength Comprehensive data analysis	• Continuous display of relative and absolute values for both IR and UV
Reliable and safe system	• Complete fail safe operation system, UL1998 compliant • Safe output relays by dynamic operation • Mechanical shutter for continuous & efficient self-check • False flame signal detection • No backup battery required: settings stored permanently in flash memory • FM and CSA certified
Useful and standard connections	• Independent output and relays for UV and IR signals • 0 or 4 (selectable) to 20mA analog flame level output • Cooling air connection on scanner head • Plug-in module
Physical constraints	• Compact size of the scanner head • High temperatures resistant
Application for various types of installations	• Suitable on boilers, dryers, furnaces and kilns • For applications like power generation, coke (steel plants), ethanol production, chemical processes, refineries, methane tankers, pulp and paper plants, cement works
General features	• Multilayer, surface mount technology with flash memory microcontroller (RoHS standard) • No aperture disks or frequency filter necessary • Low power consumption (12-15VA max.)
