More Information
Summary:A sensor carrier for an in-tube inspection scraper has setting places for installation of monitoring sensors responsive to any diagnostic parameters of a pipeline being inspected. The carrier includes a set of kinematically interconnected sensor supports that are subjected to an elastic force in the radial direction from the carrier axis. The supports are made as elastic ring-shaped elements or as rows of interconnected elements adjoining the pipe wall or are fixed on elastic components such as rings or sectors of sleeves, and/or are connected to a housing capable of bending. Installed on the supports between the sensors and the internal surface of the pipeline are elastic gaskets. The carrier allows one to increase the efficiency of the flaw detection in pipelines having defects of geometry in the cross section.
