The L2200D1810-JH pyroelectric detector from Laser Components was developed to make H2 flames, which are invisible to the human eye, visible. For this purpose, the component includes a newly developed filter combination for IR emissions at 2.95µm. This makes it possible to detect hot water molecules produced during the combustion of hydrogen. A built-in reference prevents false alarms.
Hydrogen engines are increasingly being considered as an alternative to gasoline and diesel engines. Flame detection is a decisive factor in both burner control in the engine and safety at filling stations.
