Abstract
A plug-in sensor is provided which is suitable for determining at least one parameter of a fluid medium flowing in a main flow direction, especially of an intake air mass of an internal combustion engine flowing through a flow pipe. The plug-in sensor has a plug part that is able to be mounted in the flowing fluid medium, in a specified alignment to the main flow direction. In the plug part, at least one flow channel is provided having at least one inlet opening and at least one outlet opening, in the at least one flow channel at least one sensor is accommodated for determining the at least one parameter. The plug part has a profile at which at least one local pressure minimum sets in in the flowing fluid medium. The at least one outlet opening is situated at the side of the plug part, in the region of the at least one pressure minimum.
