Abstract

Le dispositif est constitué par une clé de serrage (5) portant une capsule de mesure (8) montée libre dans la partie creuse (4) de la clé (5) et destinée à venir en appui sur une extrémité de la broche (2) subissant la prétension. Un capteur émetteur et récepteur d'ultrasons (21) disposé à l'intérieur de la capsule de mesure (8) est mis en appui sur l'extrémité de la broche (2) par un ressort (25) intercalée entre la capsule (8) et le capteur (21) La capsule (8) elle-meme est mise en appui sur l'extrémité de la broche (2) par un moyen élastique (9) porté par la clé de serrage (5).
