Abstract

L'invention concerne une jauge de contrainte à fil vibrant Elle concerne notamment une jauge de contrainte à fil vibrant comprenant une bande de base métallique allongée adaptée à être fixée invariablement à un élément structural, un tube de métal dont l'un des côtés est soudé invariablement à ladite bande le long de sa longueur, un fil vibrant s'étendant coaxialement dans ledit tube, à une certaine distance de sa paroi intérieure, chaque extrémité dudit tube étant sertie de façon à enserrer l'extrémité du fil, ledit fil ayant une tension predéterminée qui est maintenue par ledit sertissage. L'invention s'applique, en particulier, aux appareils de mesure et, en particulier, aux jauges pour mesurer les contraintes et les efforts auquels sont soumis les matériaux de construction.
