Abstract
A sensor system for determining a parameter of a fluid medium, e.g., an intake air mass flowing through a channel, includes at least one sensor chip situated in the channel for determining the parameter, which sensor chip is accommodated in a sensor carrier which (i) protrudes into the channel and (ii) has a leading edge situated transverse to the flow of the fluid medium. At least one vortex generator is provided, at least in the region of the leading edge, and configured for forming secondary flows in the flowing fluid medium in the region of the sensor carrier, for avoiding or reducing the entry of particles. The secondary flows extend in a plane essentially perpendicular to the main flow direction of the fluid medium, e.g., facing away from the sensor area.
