A sensor for determining at least one parameter of a fluid medium, in particular an induction air-mass flow of an internal combustion engine, flowing through a measuring channel. The sensor has a sensor housing, in particular a plug-in sensor, which is introduced or may be introduced into a flow pipe and in which the measuring channel is developed, and at least one sensor chip, disposed in the measuring channel, for determining the parameter of the fluid medium. The sensor housing has a plurality of channel walls, which delimit the measuring channel. The sensor chip is situated on a sensor carrier. At least in the region of the sensor carrier, at least a first channel wall of the plurality of channel walls and a second channel wall of the plurality of channel walls, which differs from the first channel wall, or the sensor carrier have at least partly magnetic properties.

Sensor for determining at least one parameter of a fluid medium streaming through a measuring channel

A sensor is provided for determining at least one parameter of a fluid medium flowing through a measurement channel, in particular an intake air mass flow of an internal combustion engine. The sensor has a sensor housing, in particular a plug-in sensor that is inserted into or is insertable into a flow tube, in which sensor a measurement channel is fashioned, and has at least one sensor chip situated in the measurement channel for determining the parameter of the fluid medium. The sensor housing has an electronics compartment for accommodating an electronics module and has an electronics compartment cover for closing the electronics compartment. The electronics compartment cover has, at least in part, electrically conductive properties. For example, the electronics compartment cover is placed onto the electrical ground of the sensor and, viewed in projection, partly or completely covers the sensor chip.

A sensor for determining at least one parameter of a fluid medium flowing through a measuring channel, in particular an intake air mass flow of an internal combustion engine. The sensor includes a sensor housing, in particular a plug-in sensor which is inserted or is insertable into a flow tube, in which a channel structure is formed, which includes the measuring channel, and at least one sensor chip situated in the measuring channel for determining the parameter of the fluid medium. The sensor housing includes an inlet into the channel structure, which is oriented away from a main flow direction of the fluid medium, and at least one outlet from the channel structure.
