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. The channel structure is delimited by wall sections. The wall sections have at least partially electrically insulating properties. Areas of the sensor housing adjoining the wall sections have electrically conductive properties.

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

A system for rotationally securely plugging a sensor into a through-passage of a flow channel, the sensor including a sensor housing, the through-passage having an inner wall delimiting the through-passage and first and second inside diameters extending respectively along a first axis and a second axis, perpendicular to the first axis, the first inside diameter being greater than the second inside diameter, a plug-in direction of the sensor housing into the through-passage defining a third axis essentially perpendicular to the first and second axis, the sensor housing having a longitudinal extension area along the third axis and being insertable into the through-passage. To ensure rotationally secure assembly of the sensor in its setpoint angular position, at least one protrusion is provided so that the sensor housing, in a plugged-in state, is rotatable in the through-passage by no more than 0.5&#xb0; about the third axis.

System for rotationally securely plugging a sensor into a through passage of a flow channel

A device for detecting at least one flow characteristic of a fluid medium, in particular for detecting an air mass flow in the intake air of a motor vehicle, includes at least one flow channel, through which the fluid medium may flow, and at least one sensor element, which is situated in the flow channel, for detecting the flow characteristic. The sensor element has at least one heating element. The device includes at least one bidirectional electrical interface. The device is configured to receive information and transmit information via the bidirectional electrical interface.

Device for detecting at least one flow characteristic of a fluid medium

A device for determining at least one parameter of a fluid medium, in particular an intake air mass of an internal combustion engine. The device comprises a sensor chip for measuring the parameter and a control and evaluation electronics having a circuit carrier. The sensor chip is situated on a chip carrier capable of being introduced into the fluid medium. The chip carrier comprises a projection of the circuit carrier developed in one piece with circuit carrier, the sensor chip being fixed in place on the projection.
