FIELD: machine building.
SUBSTANCE: invention discloses systems and methods (versions) for measuring parameters of solid particles in a vehicle exhaust system. In one example, the system comprises a first outer tube with a number of inlet openings on an upstream surface, a second inner tube with a number of inlet openings on a downstream surface and a solid particles sensor located inside the second inner tube. Second inner tube can be located inside the first external tube so that the central axis of the second inner tube is parallel to the central axis of the first external tube.
EFFECT: technical result is improvement of operation and reliability of sensor.
