Abstract
A sampling assembly for an exhaust gas aftertreatment system includes a body layer, an outer bowl, a first sampler, and an inner bowl. The body layer defines a cylindrical passage. The outer bowl is coupled to the body layer. The first sampler extends circumferentially along the body layer to the outer bowl. The first sampler includes a first sampler channel and a first sampler aperture. The first sampler channel is configured to provide exhaust gas into the outer bowl. The first sampler aperture is configured to receive the exhaust gas from the cylindrical passage and provide the exhaust gas into the first sampler channel. The inner bowl is disposed at least partially within the outer bowl and configured to receive the exhaust gas from the outer bowl and provide the exhaust gas into the cylindrical passage.
