Abstract

Systems and methods are described for sensing particulate matter in an exhaust system of a vehicle. An example system comprises a first outer tube with a plurality of intake apertures on an upstream surface, a second inner tube with a plurality of intake apertures on a downstream surface, and a particulate matter sensor placed within the second inner tube. The second inner tube may be positioned within the first outer tube such that a central axis of the second inner tube is parallel to a central axis of the first outer tube.
