Sensor arrangement for determining flow characteristic of fluid medium, particularly intake air mass of internal combustion engine, has wing grid which is arranged in main flow direction upstream of plug-in sensor

摘要

The sensor arrangement has a wing grid which is arranged in the main flow direction (18) upstream of a plug-in sensor (12). The wing grid is provided for deflecting the fluid medium in the main flow direction and has multiple wings and webs. The wings are arranged with variable radius in partially circular or elliptical manner. An angle of incidence of the wings from the outside is smaller with respect to the wing grid.
