PLUG-IN SENSOR WITH IMPROVED FLOW DYNAMICS

摘要

The invention relates to a plug-in sensor (110) for determining at least one parameter of a fluid medium flowing in a main flow direction (126), especially a suction air mass of an internal combustion engine, flowing through a flow tube. The plug-in sensor (110) comprises a plug-in part (116) which can be introduced into the flowing fluid medium in a pre-defined orientation in relation to the main flow direction (126). The plug-in part (116) is provided with at least one flow channel (124) comprising at least one inlet (128) and at least one outlet (610). At least one sensor (144) for determining the at least one parameter is received in the at least one flow channel (124). The plug-in part (116) comprises a rounded approach flow side (148) which is oriented away from the main flow direction. The at least one main flow channel (124) has at least one inlet (128) in the region of the rounded approach flow side (148). The plug-in part (116) at least partially has a carrier surface profile (210) which is designed in such a way that the fluid medium has an asymmetrical flow profile when the plug-in part (116) is introduced into the flowing fluid medium.
