Abstract

A sensor arrangement is described for determining at least one parameter of a fluid medium flowing through a measuring channel, particularly of an intake air mass flow of an internal combustion engine. The sensor arrangement includes a sensor housing, in particular a plug-in sensor which is introduced or may be introduced into a flow tube and in which the measuring channel is formed, and at least one sensor chip which is situated in the measuring channel for determining the parameter of the fluid medium. The sensor chip is attached to a sensor carrier protruding into the measuring channel. The sensor carrier is designed in such a way that it has a chord. The chord has a length of 4.5 mm to 6.5 mm. In a preferred refinement, the sensor carrier is shaped like a double ellipse or a diving board.
