The invention proposes a sensor arrangement (10) for determining at least one parameter of a fluid medium flowing through a channel structure (22), in particular an intake air mass flow of an internal combustion engine. The sensor arrangement (10) comprises a sensor housing (12), in particular a plug-in sensor which is introduced or can be introduced into a flow tube and in which the channel structure (22) is formed, and at least one sensor chip (42) which is arranged in the channel structure (22) and is intended to determine the parameter of the fluid medium. The sensor housing (12) comprises an inlet (34) in the channel structure (22), which is oriented away from the main flow direction (36) of the fluid medium, and an outlet (96) from the channel structure (22). The channel structure (22) has a main channel (24) and a measurement channel (28). Said measurement channel (28) branches off from the main channel (24). The sensor chip (42) is arranged in the measurement channel (28). The main channel (24) and the measurement channel (28) lead together into the outlet (96) from the channel structure (22). |
