Pyroelectric Detectors for the Detection of Hydrogen Flames
Photonics News No 90
More Safety for the Driving Force of the Future
Flame detection is a crucial safety feature for the hydrogen-powered cars of the future. This applies to burner control in the engine, as well as 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.
