Crowcon Fgard UVIR | UV/IR Flame Detector | 3 sensitivity settings, <5 s response
The Crowcon Fgard UVIR combines ultraviolet and infrared sensing in an explosion-proof housing to detect hydrocarbon fires outside the visible spectrum. Three selectable sensitivity settings let it be matched to each location so that neighbouring detectors do not cross-vote, giving flexibility across different applications. It has been shown to detect a hydrocarbon pan fire at over 130 ft in less than 5 seconds.
Key features
- Ultraviolet-infrared flame sensing
- Three sensitivity settings to suit each application
- Microprocessor-controlled heated optics
- Automatic lens and circuit verification
- FM 3260 and EN 54-10 approvals
