A device for measuring distance between walls of coaxial cylindrical screens is provided. Rotation of motors is rotated to screw bars and rotation of the screw bars is converted to translational movement of gauge bars. The numbers of rotation of the screw bars corresponding to length of projection of the gauge bars from their withdrawn positions to positions at which they abut against wall surfaces of the screens are measured by rotary encoders and the distance between wall surfaces of the screens thereby is measured. A main body of the device is fixed between the wall surfaces of the screens by means of the projecting gauge bar and a pair of main body supporing units.
Dispositif conçu pour mesurer la distance entre les parois de tamis cylindriques coaxiaux. Des moteurs transmettent leur rotation à des barres comportant un pas de vis, et cette rotation est à son tour convertie en un mouvement de translation communiqué à des barres de jauge. Des codeurs rotatifs servent à mesurer le nombre de rotations des barres à vis correspondant à la longueur de la partie saillante des barres de jauge entre leur position rentrée et la position où elles se trouvent lorsqu'elles butent contre la surface des parois des tamis. De cette manière, on peut mesurer la distance entre la surface des parois et les tamis. Le corps principal de ce dispositif est assujetti entre les parois des tamis grâce à la barre de jauge en saillie et à une paire d'éléments d'appui de ce corps principal.
