Abstract

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.
