APPARATUS FOR MEASURING THE WALL THICKNESS OF TUBES |
摘要 |
<p>Title of the Invention "Apparatus for measuring the wall thickness of tubes" Apparatus for measuring the wall thickness of a moving tube, for example an extruded tube of synthetic plastics material, comprises means for location in a stationary position within the tube and adapted to present at least one measuring body in resilient contact with the inner wall of the tube, and an external sensor for sensing the position of the measuring body. A mechanical linkage incorporating means engaging the tube wall is arranged to lift the measuring body away from the tube wall when excessive friction between the tube wall and the engagement means indicates a condition liable to damage the measuring body.</p> |
