FIBER-OPTIC MOVEMENTS INDICATOR Russian patent published in 2006 - IPC G01B1/00 

FIELD: engineering of measuring equipment, in particular, engineering of fiber-optic measuring transformers of movements, possible use for measuring pressure under conditions of explosion-hazardous environment.

SUBSTANCE: fiber-optic movements indicator has emitter, reflector, radiation receiver, fiber light guide. Vertical holder and emitter are held immovably relatively to controlled object. Emitter and radiation receiver are held on controlled object by rings or yokes. Rings are pinned onto controlled object with gap, greater than maximally possible linear extension of object dimensions, and are mounted on posts. Posts are positioned on earth surface. Yokes are pinned along perimeter of object through rubber inserts with thickness greater than maximal possible linear extension of object dimensions. On lower portion of each yoke a screw is positioned. Screw is in contact with surface of controlled object.

EFFECT: simplified construction.
