MICROSCOPTER FOR DETECTING DISTANCE VARIATION OR CYCLE OF DISTANCE VARIATIONS BETWEEN TWO POINTS OR ZONES OF A STRUCTURE DURING SOLICITATION

摘要

The present invention relates to a passive and reversible sensor for deformations along a direction OX of a structure, in particular during temperature cycles or mechanical stresses to which said structure is subjected, this sensor comprising detection means and counting means, characterized in that it comprises means for detecting and counting the cycles of distance variations between two points or zones of a structure, these means comprising a support having a first and a second part each having an anchoring zone, these zones d anchoring being able to be fixed respectively to one and the other of said two points or zones of the structure and being constituted by studs, notches and / or bores and being of smaller dimensions than those of the first and second second parts, the counting means being associated with each of said first and second parts of the support.
