Systems and methods for sampling exhaust gas

A sampling assembly 144 for use with a NOx sensor 146 comprises a body layer 206, an outer bowl 236, a first sampler 210 and a NOx sensor coupling 238. The body layer defines a cylindrical passage. The outer bowl is coupled to the first body layer and provides exhaust gas to the cylindrical passage....

More Information
Summary:A sampling assembly 144 for use with a NOx sensor 146 comprises a body layer 206, an outer bowl 236, a first sampler 210 and a NOx sensor coupling 238. The body layer defines a cylindrical passage. The outer bowl is coupled to the first body layer and provides exhaust gas to the cylindrical passage. The first sampler is disposed within the cylindrical passage and extends circumferentially along the first body layer to the outer bowl. The first sampler has a first sampler channel 218 to provide exhaust gas into the outer bowl, and a first sampler aperture 214 to receive exhaust gas from the cylindrical passage and provide exhaust gas into the first sampler channel. The NOx sensor coupling is coupled to the outer bowl and comprises a NOx sensor coupling opening (240, fig 3) to receive the NOx sensor. A sampling assembly includes a second sampler 212.
