Abstract

La tete de mesure est disposée à l'extrémité libre d'une tige de support (8) et est munie d'un potentiomère rotatif (11) qui est accouplé à un organe tournant avec interposition d'un accouplement à friction (13). L'organe tournant (16) comprend au moins un coulisseau (17) qui pénètre dans une gorge hélicoidale (24) d'une douille de guidage et qui fait tourner le potentiomètre rotatif lors du déplacement de la tige de pistion.
