UV/IRS-H2 & UVS-H2 Flame Detectors
Ultraviolet and Infrared Sensors for Hydrogen & Silane Flame
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!

Two Radiation Wavelengths Necessary For Alarm—
Minimize False Alarm Events (UV/IR-H2 only)

Extremely Low Power Consumption Increases
Uptime and Lowers Overall Costs

Wide Voltage Range Allows For Greater Stability
and System Compatibility

Manual and Automatic Testing of Optical Surfaces
— Constatly Monitors Internal Electronics

Wide Area Coverage, Extended Range with Fast
Response Times

Designed for Extreme Conditions, Operational
From -50°C — +75°C

Analog, Relay, and HART® Outputs Available

Global Certifications and Approvals
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
PMS - Uncoated
PMS - Coated
CMYK

Field-selectable Sensitivity and Delay Settings
Allows Operators To Fine Tune At Installation Site

3 Year Warranty Electronics / 2 Years on Sensors
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!
