SEMI-AUTOMATIC DEVICE FOR CONTINUOUSLY LOCATING XY COORDINATES OF SINGULAR POINTS WITHIN A MOVING SURFACE

摘要

The device, which comprises: a control plane (1), a means (6) for measuring the displacement of the surface (10) to be controlled, and a central input and recording unit (11), is characterized in that it also includes a means for localizing the second (Y) co-ordinate consisting of: a first means (15) for displacing a visible reference point along an axis transversal to the surface (10), a second means (12) for input and/or recording of the position of said reference point.
