DescriptionThe FGard H2 hydrogen flame detector by Crowcon is a groundbreaking solution that addresses the critical safety challenge of detecting colourless hydrogen gas and flames in industries reliant on hydrogen. Traditional multi-spectral flame detectors are inadequate for this task, as they cannot discern hydrogen flames. The FGard H2 is optimised exclusively for hydrogen flame detection, ensuring the safety of both personnel and facilities.Delivering unparalleled performance, the FGard H2 boasts a remarkable response time of just four seconds. This speed is validated for a 36-inch plume-size hydrogen flame at a distance of 40 metres, enabling swift and reliable detection even in the most demanding industrial environments.Designed with intelligent heated optics, the flame detector actively prevents condensation, ice, or water from obstructing the lens. Its advanced optical verification system eliminates the need for a reflector, significantly reducing the risk of false alarms.Setting a new benchmark in reliability, the FGard H2 comes with a market-leading five-year warranty. Its performance is validated by Factory Mutual (FM), underlining its exceptional quality and dependability.The detector incorporates advanced detection technology specifically designed to identify hydrogen flames. Using a unique combination of sensors and algorithms, it accurately discerns the spectral signature of hydrogen combustion from other sources.At its core lies a triple infrared (IR) sensing system that monitors three specific IR wavelengths associated with hydrogen combustion. This multi-spectral approach offers high sensitivity and selectivity, minimising the chance of false alarms caused by sunlight, hot surfaces, or non-hydrogen flames.Intelligent signal processing algorithms further enhance its accuracy. These continuously analyse incoming data from the IR sensors to identify patterns and characteristics unique to hydrogen flames, even in challenging industrial environments with potential interference.Built to withstand harsh conditions, the FGard H2 features a robust stainless-steel housing and holds hazardous area certifications. It complies with key international standards, including ATEX and IECEx certification for Zone 1 and Zone 2 hazardous areas, FM approval for Class I, Division 1 and Division 2 locations, and SIL 2 certification for functional safety applications.Despite its advanced capabilities, the detector is designed for straightforward integration and maintenance. It offers flexible mounting options for optimal coverage, compatibility with various control and safety instrumented systems, remote self-testing and diagnostics, and simple field-replaceable components to minimise downtime.
