Sensor arrangement for determining at least one parameter of a fluid medium flowing through a channel structure

A sensor system is provided for determining at least one parameter of a fluid medium flowing through a channel structure, e.g., an air mass flow of an internal combustion engine. The sensor system has a sensor housing, e.g., a plug-in sensor that is introduced or can be introduced into a flow tube,...

Beschreibung
Zusammenfassung:	A sensor system is provided for determining at least one parameter of a fluid medium flowing through a channel structure, e.g., an air mass flow of an internal combustion engine. The sensor system has a sensor housing, e.g., a plug-in sensor that is introduced or can be introduced into a flow tube, in which the channel structure is formed, and at least one sensor chip, situated in the channel structure, for determining the parameter of the fluid medium. The sensor housing has an inlet into the channel structure, oriented opposite a main direction of flow of the fluid medium, and an outlet from the channel structure. The channel structure includes a main channel and a measurement channel. The measurement channel branches off from the main channel. The sensor chip is in the measurement channel. The main channel and the measurement channel discharge together into the outlet from the channel structure.
