Abstract: An outlet assembly for an aftertreatment system comprises an outlet conduit configured to receive an exhaust gas from the aftertreatment system. The outlet conduit defines a first aperture through a sidewall thereof. An outlet passage is disposed within the outlet conduit. The outlet passage comprises a first end facing an upstream side of the outlet conduit and a second end located downstream from the first end. The second end is fluidly coupled to the first aperture. A hole is defined through an outlet passage sidewall at a radial location that is proximate to the sidewall of the outlet conduit. The hole is configured to allow a sensor to be inserted therethrough into a flow path defined by the outlet passage. The outlet passage is configured to receive a portion of the exhaust gas from the outlet conduit such that the sensor is exposed to the portion of the exhaust gas.

Abstract: A water intrusion cover for a sensor probe in an exhaust system is provided. The water intrusion cover includes a main body portion having a substantially cylindrical shape, an inlet opening, and an outlet opening. The inlet opening and outlet opening are formed in a sidewall of the main body portion and are fluidly coupled to form a continuous flow path defined by a surface that, in a cross-section perpendicular to an axis of the main body portion, curves from the inlet opening to the outlet opening. The water intrusion cover further includes a shoulder portion having a substantially cylindrical shape. The main body portion and the shoulder portion collectively define a central passage for the sensor probe.
