1. An exhaust gas sensor system, comprising:

  • a sensor element;

    an inner conical chamber disposed around the sensor element; and

    an outer chamber having an inclined end for collecting exhaust gas particles, said outer chamber being substantially disposed around the inner chamber to redirect a flow of an exhaust gas stream having an original direction by allowing the exhaust gas stream to strike a surface of the inner chamber to change the original direction of the flow to a substantially perpendicular direction relative to the original direction, then to substantially reverse the substantially perpendicular direction of the flow to create a substantially reversed flow within the inner chamber.
