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.The measuring head is arranged at the free end of a support rod (8) and is provided with a rotary potentiometer (11) which is coupled to a rotating member with the interposition of a friction coupling (13). The rotary member (16) comprises at least one slide (17) which penetrates into a helical groove (24) of a guide sleeve and which rotates the rotary potentiometer during the movement of the piston rod.
