Flame detection is a crucial safety feature for hydrogen-powered cars of the future. This applies to burner control in the engine, and to open flames at hydrogen filling stations.
H2 flames are invisible to the eye but can be detected by IR detectors (e.g., the L2200D1810-JH from LASER COMPONENTS). With a newly developed IR filter combination, this pyroelectric detector measures the IR emissions of water molecules at 2.95 µm as produced during the combustion of hydrogen. This component is supplied as a dual-channel detector in a rugged TO-39 housing.
