Abstract

L'invention a pour objet un dispositif de transformation d'une force en une grandeur physique. Ce dispositif se caractérise en ce qu'il comporte une pièce comprenant une poutre et un élément tubulaire de longueur inférieure à celle de ladite poutre, la poutre et l'élément tubulaire étant raccordés de façon étanche par l'une de leurs extrémités de façon telle que ledit élément tubulaire soit disposé autour de ladite poutre et l'extrémité libre de ladite poutre étant soumise à l'application de la force. Application à la mesure de niveaux, de masses, de pressions et de densités.
