<p>The apparatus measures the distance between two points of a structure with a view to detecting structural deformation. It includes a sensor with two sensitive elements which are linked respectively to these two points. The first element has an area comprising alternating portions, called graduations (18), which are electrically conducting, and electrically insulating portions, called intervals (19). The second element comprises an electrically conducting component called the cursor (21). Part of the cursor may be moved against the area of the first element. It is always in contact with at least one graduation. The graduations and the cursor are connected to a detecton apparatus (29) which deduces the distance between the two points of the structure.</p> |
