Abstract:
1. A sampling probe for analyzing a gas in a fluid stream, comprising: (a) a tube for being inserted into the fluid stream substantially perpendicular thereto to cause the fluid stream to separate and flow around the tube; (b) a first opening extending along a first axially extending face of the tube downstream relative to the fluid stream such that a portion of the gas enters the tube through the first opening for analysis within the tube; (c) a second opening extending along a second axially extending face of the tube such that the gas that enters the tube through the first opening exits the tube after analysis into the fluid stream through the second opening; and (d) a third opening extending along a third axially extending face of the tube and aligned with the second opening to allow gas that enters the tube through the first opening to exit into the fluid stream through the third opening.
