The FL500-H2 is a UV/IR flame detector designed specifically to detect hydrogen (H2) fires. The sensors monitor optical radiation emitted by a hydrogen flame in both the UV and IR spectral ranges while at the same time rejecting nuisance false alarm sources common within industrial job sites.
The detector’s flame sensing technology relies on the ultraviolet sensor to provide a quick response (<3 seconds) and the infrared detector monitors radiation emitted by a flame over a wide 130-deg. fov. UV/IR sensor technology offers increased immunity, operates at faster speeds, and is suited for both indoor and outdoor use.
