Description

technical field

[0001] The invention belongs to gas oxygen concentration detection technology, and relates to an improvement of an oxygen concentration detection structure of oxygen-enriched air used for an airborne separator. Background technique

[0002] The separators currently onboard can generate oxygen-enriched air from the aircraft's own compressed air source over a very long period of time. Passengers can thus be supplied with oxygen-enriched air not only during the descent of the aircraft but also during its temporary flight altitude. Such as: Chinese patent application CN1549785A (for the method and device of dispensing oxygen-enriched air for aircraft passengers) has announced that "separator 2 includes an output pipeline 8 and a pipeline 10, wherein, nitrogen-enriched air flows out from pipeline 8, Oxygen-enriched air flows in pipeline 10. Said pipeline 10 is provided with a sensor 12 to monitor the oxygen concentration of the oxygen-enriched air flowing through...
