Honeywell FS20X Flame Detector

Feature & Principle

It is Honeywell FS20X multi-spectrum flame detector, adopts UV, dual infrared and visible light composite sensing technology. Dual CPU fail-safe signal processing, effectively distinguish real flame from sunlight, welding and other interference sources, reduce false alarms. It detects hydrocarbon and non-hydrocarbon flame, suitable for smoky fire scenarios. Support 4-20mA analog, relay alarm output, optional HART communication module for parameter configuration and diagnosis. With IP66 protection and ATEX/IECEx explosion-proof certification, widely deployed in petrochemical, offshore platform, LNG station, turbine room.
