Abstract: A particulate sensor assembly may include a particulate sensor and a sensor housing. The particulate sensor may be configured to measure a quantity of particulate matter in a stream of exhaust gas from a combustion engine. The sensor housing may receive the particulate sensor and may include a cavity in which the particulate sensor is exposed to the exhaust gas. The cavity may be defined by a porous structure through which the exhaust gas may flow. The porous structure may filter a predetermined amount of particulate matter from the exhaust gas as the exhaust gas enters the cavity.
