Abstract

The invention relates to a mechanical-electronic system for the laser measurement of the thickness of moving sheets with perpendicularity correction. The inventive system comprises: a C-shaped head (1); two opposing laser sensors (4 and 8); three sonar sensors (3, 5 and 6) which are arranged in a triangle and which are fixed to the head (1) by means of a support (2); a control automaton and mechanical means for positioning the head (1) along a horizontal axis (x), a vertical axis (y), a rotational axis (r) and an angular axis (a), which are used to ensure that the beam from the laser sensors (4 and 8) is perpendicular to the surface of the material (7) of which the thickness (e) is to be measured.
