Abstract

La présente invention a pour objet un dispositif de mesure de l'épaisseur de paroi de tubes à l'aide d'un corps de mesure à suspension stable et appliqué étroitement contre la paroi sous l'effet de ressorts. Les corps de mesure sont montés sur des bras de parallélogrammes dont un ou plusieurs pivots sont souples et supportés par une pièce commune de forme tubulaire. Un dispositif de butée, d'un diamètre inférieur à celui de la circonférence des extrémités périphériques des corps de mesure, permet de choisir la gamme de mesure des diamètres dans lequel ils peuvent se déplacer. Le dispositif est destiné au contrôle des épaisseurs de paroi des tubes en matière plastique à la sortie d'une extrudeuse.
