New device delivers UV/IR sensing for hydrogen detection

By Chemical Engineering |

MSA Safety

The FL500-H2 (photo) is an ultraviolet/infrared (UV/IR) flame detector designed specifically to detect hydrogen fires. The FL500-H2 sensors monitor optical radiation emitted by a hydrogen flame in both the UV and IR spectral ranges while simultaneously rejecting nuisance false-alarm sources that are common within industrial job sites. The detector’s flame-sensing technology relies on the UV sensor to provide a quick response (<3 s) and the IR detector monitors radiation emitted by a flame over a wide 130-deg field of view. UV/IR sensor technology offers increased immunity, operates at faster speeds, and is suited for both indoor and outdoor use. The detector’s design features a compact footprint for ease of installation, along with a rugged stainless-steel housing. The easy-to-read display includes three LED indicators that show normal operation, fault condition and an alarm. — MSA Safety, Cranberry Township, Pa.
