Exhaust gas sensor module

摘要

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.

1. A fluid treatment system, comprising:
a housing defining a fluid flow channel through which fluid is flowable in a fluid flow direction from an inlet of the housing to an outlet of the housing; a first fluid treatment device positioned within the fluid flow channel between the inlet and outlet of the housing; a second fluid treatment device positioned within the fluid flow channel between the first fluid treatment device and the outlet of the housing; and at least one sensor module comprising:
a sensor probe positioned within the fluid flow channel between the first and second fluid treatment devices, the sensor probe comprising a plurality of hollow arms extending radially outward from a radially inward portion of the fluid flow channel to a radially outward portion of the fluid flow channel, each of the plurality of arms comprising a plurality of apertures facing a direction substantially opposite the fluid flow direction, the apertures being communicable in fluid receiving communication with a sample portion of fluid flowing through the fluid flow channel,at least one sensor communicable in sensing communication with fluid received through the apertures, andan extractor portion coupled to the sensor probe, the extractor portion comprising the sensor and the extractor portion being communicable in fluid receiving communication with the plurality of hollow arms of the sensor probe, and wherein the extractor portion comprises an outlet positioned between the second fluid treatment device and the outlet of the housing, the outlet of the extractor portion being communicable in fluid supplying communication with fluid flowing through the fluid flow channel of the housing, wherein the extractor portion comprises a bypass line extending about the second fluid treatment device, the bypass line fluidly coupling the sensor probe and the outlet of the extractor portion.
