| 发明名称 | Sensor device for detecting at least one flow property of a fluid medium | ||
| 摘要 | A sensor device for detecting a flow property of fluid medium, e.g., an air flow in the intake tract or the charge air tract of an internal combustion engine, includes: a sensor housing introduced into the air flow and having at least one housing body, at least one cover, and at least one channel through which the fluid medium flows; a sensor element for detecting the flow property, the sensor element being held on a top side of a carrier. The carrier is situated at least partially in the channel and has a cross section which becomes wider in parallel with the main flow direction of the fluid medium at the location of the sensor element in a sectional plane in parallel to the main flow direction of the fluid medium in the channel. | ||
