Xenon gas sensor for monitoring and regulating Xenon concentrations, in flowing media

摘要

The Xenon gas sensor has a heat conductivity sensor (1) as a receiver system for the hat shaped cover (3) of a sensor resistance (4) and flow against sensor does not result in the direction of the opening of the hat shaped cover (3). The sensor (1) has a measuring resistance (4) and a reference resistance (2). The sensor housing (8) is made of aluminium. The sensor housing is regulated at a constant temperature. An electronic evaluation unit (10) is integrated in the sensor housing. A temperature regulator (7) is integrated in the sensor housing. The inner chamber (9) of the sensor housing is filled up with an electrically and thermally insulating sealing compound.
