Abstract
An apparatus for collecting a dry material sample flowing in a duct is disclosed. The apparatus includes a sample tube having a closed distal end and a sample-inlet aperture in the wall of the sample tube adjacent the closed distal end, a housing configured as a fluid cylinder with a duct end and an outlet end and a piston mounted around and connected to the sample tube and positioned within the housing. The apparatus also includes first and second sealing sleeves around and slideably supporting the sample tube. The duct end includes the first sealing sleeve and the outlet end includes the second sealing sleeve. A duct-connecting structure extends between the duct end of the housing and the duct. The sample tube is a piston rod within the fluid-cylinder housing, and the fluid-cylinder housing is configured to extend and retract the sample tube within the duct.
