Abstract

L'invention concerne une clé instrumentée (1) de tirefonds comprenant un arbre de transmission (5) présentant une extrémité (5b) destinée à coopérer avec un embout (3) conçu pour coopérer avec un tirefond ou un boulon ferroviaire (200), la clé instrumentée (1) comprenant en outre un contrôleur de couple (4) de serrage configuré pour mesurer et contrôler le couple du tirefond ou du boulon (200), caractérisée en ce que le contrôleur de couple (4) comprend au moins un élément de mesure (7) configuré pour mesurer une valeur de couple de serrage en convertissant la déformation de l'arbre de transmission (5) de la clé instrumentée (1) en variation de résistance électrique.The invention relates to an instrumented wrench (1) comprising a transmission shaft (5) having an end (5b) intended to cooperate with a tip (3) designed to cooperate with a lag bolt or a rail bolt (200), the an instrumented key (1) further comprising a torque controller (4) configured to measure and control the torque of the lag bolt or bolt (200), characterized in that the torque controller (4) comprises at least one torque element measurement (7) configured to measure a tightening torque value by converting the deformation of the transmission shaft (5) of the instrumented key (1) into variation of electrical resistance.
