Abstract

Ce dispositif est du type comportant un carter qui peut être fixé par rapport à l'objet à mesurer et dans lequel est montée, pour tourner, une broche filetée entraînée par un moteur cette broche permettant de déplacer un palpeur vers l'objet à mesurer et, après déclenchement d'un signal de contact de l'en éloigner, le résultat de la mesure étant déduit de la course de déplacement de la broche filetée, le palpeur étant en outre isolé électriquement du carter et de l'objet à mesurer. Suivant l'invention, il est caractérisé en ce que la course de déplacement est déterminée à partir de la rotation de la broche 3, 30 dans un plan transversal, ainsi que du pas de filetage de cette broche.This device is of the type comprising a casing which can be fixed relative to the object to be measured and in which is mounted, to rotate, a threaded spindle driven by a motor, this spindle making it possible to move a probe towards the object to be measured and , after triggering a contact signal to move it away, the result of the measurement being deduced from the travel path of the threaded spindle, the probe being furthermore electrically isolated from the housing and from the object to be measured. According to the invention, it is characterized in that the displacement stroke is determined from the rotation of the spindle 3, 30 in a transverse plane, as well as from the thread pitch of this spindle.
