Gas sensor for measuring gas concentration, has beam splitter, catalytic emitter, measurement and reference radiation detectors that are arranged in housing which has partial gas permeable areas

摘要

A beam splitter (5) divides the infrared radiation from a catalytic emitter (1) so that the infrared radiation might be detected by a measurement radiation detector (4) and a reference radiation detector (5). The beam splitter, catalytic emitter, measurement radiation detector, and the reference radiation detector are arranged in a housing which has partial gas permeable areas.
