Abstract

L'invention concerne une sonde destinée, au moyen d'un capteur magnétique, à mesurer la vitesse de rotation d un arbre Le capteur est relié de façon étanche à la tige de la sonde au moyen d'un soufflet et d'un ressort qui autorisent un certain déplacement axial de l'un par rapport à l'autre. Application aux techniques de télémesure, notamment de la vitesse de rotation de l'arbre du compresseur d'un turboréacteur.
