SYSTEM FOR ANALYSING THE DEFORMATION OF A TUBE

摘要

The present invention concerns a system (1) for analysing the diametrical deformation of a tube (2), comprising a sensor (12) to monitor the deformation of the tube (2), characterised in that it further comprises a deformation limiter (14, 15) for restricting to an area (21) of the tube at a right angle to the senor (12) the extent of an additional deformation of the tube (2) that goes beyond a nominal deformation.
