Abstract:
A system for extracting and conveying sampling gases from a remote location for component and quality testing by a gas-sampling device by use of a venturi-based manifold that moves a volume of motivating gases to create a venturi effect, comprising:an air extractor for creating a vacuum to draw sampling gases for testing, the air extractor comprising: a venturi having an inlet end and an outlet end; an inlet port into through which the volume of motivating gases is drawn; and a plenum extending from the inlet port to the inlet end of the venturi; a manifold for testing the sampling gases drawn by the air extractor, the manifold comprises: a housing defining a chamber; at least one manifold port through which the sampling gases from the remote location are drawn into the housing by the venturi effect created by the air extractor; and at least one sampling port through which a sample of the sampling gases drawn by the air extractor into the housing of the manifold are drawn by the gas-sampling device; and a pressure gauge for monitoring and reporting the pressure of the gases within the manifold.
