    摘要: In a sampling head (1) of an analysis arrangement (31), provision is made that a sample stream delivered via a sampling line (2) and a dilution air stream delivered through a dilution air inlet (4) are mixed together in a dilution unit (3) in such a way that a volumetric quantity entrained in at least one receiving space moved along by a movable element (8) between the sampling stream and the dilution air stream are exchanged with each other, wherein the analysis arrangement (31) has a gas analyzer (35) for the analysis of the slightly diluted sample stream and a particle determination unit (32) for the analysis of the enriched dilution air stream.

    摘要: A sensor device for detecting a flow property of fluid medium, e.g., an air flow in the intake tract or the charge air tract of an internal combustion engine, includes: a sensor housing introduced into the air flow and having at least one housing body, at least one cover, and at least one channel through which the fluid medium flows; a sensor element for detecting the flow property, the sensor element being held on a top side of a carrier. The carrier is situated at least partially in the channel and has a cross section which becomes wider in parallel with the main flow direction of the fluid medium at the location of the sensor element in a sectional plane in parallel to the main flow direction of the fluid medium in the channel.
