Automotive sensor arrangement for determining parameter of fluid medium e.g. intake air mass flow flowing through channel in engine, has flow stabilizing element like flow stabilizing fin, arranged in channel downstream of sensor chip

摘要

The sensor arrangement (10) comprises a sensor housing (12) in which the channel (24) is formed. The channel is arranged in the sensor chip (30) for determining the parameter of the fluid medium. The sensor housing comprises an inlet (16) of the channel, which is arranged pointing against the main flow direction (18) of the fluid medium. An outlet (26) of the channel is formed in a surface of the sensor housing. A flow stabilizing element such as a flow stabilizing fin, is arranged in the channel downstream of the sensor chip.
