The Net Safety UVS-H2 Hydrogen Flame Detectors (formerly branded Net Safety) are specially tuned for non-hydrocarbon based flame applications where accurate and instant detection of difficult to see hydrogen and silane flame is required. Our advanced optical sensors ensure the greatest degree of UV and IR spectral bandwave matching to the radiant energy emitted by invisible hydrogen and silane flame — and the lowest degree of matching to non-fire stimuli. This provides ultra-fast alarm, an unparalleled level of false alarm immunity, as well as a field-of-view unmatched in the industry — a full 120° horizontal degrees!

Enclosed in a rugged, explosion-proof housing, the UVS-H2 is engineered for extreme applications and utilizes the latest in SMART microprocessor sensor technology. It's capable of stand-alone operation or can be connected to a variety of control devices to create a dependable fire monitoring system. The field user can define sensitivity and time delay settings to further enhance false-alarm immunity and the built-in testing routines ensure continuous operation.

The UVS-H2 is ideally suited for specialized applications where response time and a wide field-of-view are most critical — industrial and commercial locations that utilize hydrogen fuel cells, hydrogen gas generators, hydrogen refilling stations, and storage tanks as well as semiconductor facilities where silane combustion risks are commonly present. Emerson's UVS-H2 flame detectors are globally certified for hazardous locations to CSA, ANSI-UL/ISA, and ATEX technical and safety standards.
