Abstract
An exhaust gas sampling device coupled to an aftertreatment system for treating exhaust gas flowing therethrough. The exhaust gas sampling device comprises an inlet passage, an outlet passage, a sensor passage, and a sensor. The inlet passage extracts a portion of the exhaust gas from the aftertreatment system, and the portion of the exhaust gas has a physical property that that is substantially similar to an equivalent physical property of a cross section of the exhaust gas flowing through the aftertreatment system. The sensor passage is positioned fluidly between the inlet passage and the outlet passage, and the sensor is in fluid communication with the sensor passage for providing a signal indicative of a property of the portion of the exhaust gas. The outlet passage reintroduces the portion of the exhaust gas back into the aftertreatment system.
