An exhaust aftertreatment system includes an exhaust aftertreatment component housing and a sensor table coupled to an exterior surface of the exhaust aftertreatment component housing. The sensor table includes a base including footings and a first platform offset from the footings by first standoffs so to define a first air gap. The base also includes second standoffs extending from the first platform. The sensor table also includes a top plate including a second platform and third standoffs extending from the second platform. The second platform is fixedly coupled to the second standoffs so to define a second air gap between the first platform and the second platform. The sensor table further includes a first sensor module coupled to the third standoffs so to define a third air gap between the second platform and the first sensor module.

Exhaust aftertreatment sensor assembly

According to one embodiment, a sensor module includes a sensor probe that has at least two arms coupled together at a central location with each of the at least two arms extending radially outwardly away from the central location. Each of the at least two arms includes one of a plurality of openings and an elongate opening extending radially along the arm. The at least two arms define fluid flow channels therein. The sensor module also includes at least one extractor coupled to the probe. The at least one extractor includes a fluid flow channel that is communicable in fluid receiving communication with fluid flowing through the fluid flow channel of at least one of the at least two arms. Further, the sensor module includes at least one sensor that is communicable in fluid sensing communication with fluid flowing through the at least one extractor.
