Abstract

A plug-in sensor for determining an aspirated air mass of an internal combustion engine flowing through a flow pipe has a plug part, which is able to be introduced into the streaming medium with a specified orientation to the main flow direction. Provided in this plug part is at least one flow channel having at least one inlet opening and at least one outlet opening. Accommodated in the at least one flow channel is at least one sensor for determining the at least one parameter. The plug part has a rounded inflow side, which points counter to the main flow direction. The plug part at least partially has an airfoil profile, which is designed such that an asymmetrical flow profile of the fluid medium comes about when the plug part is introduced into the streaming fluid medium.
