Window 141 Flame Scanning System - 40189 WINDOW 141

A single scanner head having a combination of UV tube (ultraviolet), a high speed IR cell (infrared), and a window which allows a direct visual sight to the scanned flame through the same hole used by the sensors. It can detect coal, oil, gas and other non standard fires.

FLAME SCANNING SYSTEM

A signal processing module handling independently both UV and IR signals received from the scanner head. It displays absolute frequency counts and the strength (relative to adjustment) of UV and IR signals. A flame strength output of 0-20mA or 4-20mA, UV and IR flame on relays, and a fault relay transmit their data to the burner management system. A chassis (mounting rack) providing termination hardware for all the wiring and 1 to 8 slots to quickly plug and remove the scanner modules. A plug in data terminal DT-1 to program and diagnose the signal processing module, so only the operator having the DT-1 can modify the module adjustments. An optional FS-2 flame source to simulate an adjustable flame signal containing UV and IR light for testing the system on the field. WINDOW 141 S
CANNER H
EAD Pure UV detection (220nm peak): Unaffected by visible and sunlight radiations like a Si UV enhanced system would. Very stable IR detection (1 550nm peak) Up to 5000Hz. Not affected by visible radiations and temperature variations like for the Ge, PbS, and other cells. The visible section of the radiation is only for visual observation through the window . The following can be observed: Sight alignment of the burner flame Obstructions to be avoided Flame aspect Lens cleanness
