UV/IRS-H2 and UVS-H2 Flame Detectors

Product catalog summary
Overview: The UV/IRS-H2 and UVS-H2 flame detectors are designed for detecting non-hydrocarbon based flames, specifically hydrogen and silane, which are difficult to see. These detectors use advanced optical sensors to match UV and IR spectral bands to the radiant energy emitted by these invisible flames, ensuring fast detection and minimizing false alarms.
Key Features:
  • Dual radiation wavelengths for alarm to minimize false alarms (UV/IR-H2 only).
  • Low power consumption for increased uptime and reduced costs.
  • Manual and automatic testing of optical surfaces to monitor internal electronics.
  • Operational in extreme conditions from -50°C to +75°C.
  • Global certifications and approvals for hazardous locations.
  • Field-selectable sensitivity and delay settings for fine-tuning.
  • Wide area coverage with a 120° horizontal field of view.
  • Analog, Relay, and HART® outputs available.
  • 3-year warranty on electronics and 2 years on sensors.
Specifications:
  • Operating voltage range: 10 to 32 Vdc.
  • Power consumption varies with voltage and heater use.
  • Temperature range: Certified -40°C to +75°C, operational -50°C to +75°C.
  • Field of view: 120 degrees horizontal, 95 degrees vertical.
  • Spectral range: UV radiation 185 to 260 nanometres, IR radiation in the 3.09 micron range.
  • Response time: Less than 6 seconds depending on conditions.
  • Enclosure material: Red powdercoat with clear anodizing, copper-free aluminum, optional stainless steel.
  • Humidity range: 0 to 95% RH, non-condensing.
  • Outputs include 0 to 20 mA, Form C contacts, and HART® communication protocol.
Certifications and Approvals:
  • CSA, ANSI/UL, ATEX/IECEx, INMETRO certifications for hazardous locations.
  • NEMA Type 4X and IP66 enclosure ratings.
Ordering Information: Various models available with options for analog output, fire and fault alarm relays, HART® communication, and additional approvals. Enclosure materials include standard aluminum or optional stainless steel.
Accessories: Include termination boxes, laser alignment tools, air shield assemblies, HART® communicator ports, field of view restrictors, pipe mounting kits, sun shade kits, and universal test lamp kits.
Performance: The detectors provide fast response times for hydrogen and silane flames, with immunity to false alarms from common stimuli like sunlight and artificial lights.

UV/IRS-H2 and UVS-H2 Flame Detectors-1

Product Data Sheet 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 Field-selectable Sensitivity and Delay Settings Allows Operators To Fine Tune At Installation Site Year Warranty Electronics / 2 Years on Sensors 3 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!
