FS20X Plus UV/3IR Flame Detector
The FS20X Plus UV/3IR flame detector using Honeywell’s WideBand IR infrared technology with the addition of ultraviolet (UV) offers a flexible solution which can quickly and reliably detect Hydrocarbon, non-Hydrocarbon, and Hydrogen fires – with increased ranges of detection – even in the presence of environmental inhibitors like rain, fog and smoke.
Often suitable for hazardous locations, the FS20X Plus has several marine certifications and is SIL2 rated for safety instrumented system applications.
