Net Safety’s Hydrogen flame detectors 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!

UV/IRS-H2 & UVS-H2 Flame Detectors

Ultraviolet and Infrared Sensors for Hydrogen & Silane Flame

Enclosed in a rugged, explosion-proof housing, the UVS-H2
and UV/IRS-H2 are engineered for extreme applications and
utilize the latest in SMART microprocessor sensor technology.
They’re 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 and UV/IRS-H2 are 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.
Net Safety’s UVS-H2 and UV/IRS-H2 flame detectors are
globally certified for hazardous locations to CSA, ANSI-UL/ISA,
and ATEX technical and safety standards.

Net Safety has engineered superior UV/IR-H2 and UV-H2
flame detectors specially tuned to detect invisible H2 and
Silane flame that are also simple to operate and maintain
while delivering all the security and performance required
for high-risk, industrial installations!
