OPTICAL DISPLACEMENT TRANSDUCER

摘要

FIELD: instrumentation, measurement of mechanical stresses in building structures. SUBSTANCE: optical displacement transducer has case housing light source, blind with beveled edge and photoelectric converter presenting strip of photocells. Plane of blind is perpendicular to luminous flux and parallel to plane of strip. Case is anchored on immobile part of object and blind is connected to mobile part and is mounted for translation perpendicular to axis of strip. Axis of strip and edge of blind are arranged at some angle. EFFECT: enhanced measurement precision. 1 dwg
