FIBRE-OPTICAL SENSITIVE ELEMENT FOR CONVERTER MEASURING PHYSICAL QUANTITIES Russian patent published in 1999 - IPC

Abstract RU 2127869 C1

FIELD: converters of linear translations, acceleration, temperature, mechanical vibrations, flow velocity. SUBSTANCE: fibre-optical sensitive element for converter measuring physical quantities has immobile base, transmitting and receiving fibrous light guides which face ends are located one opposite to another, mobile inertial mass. One of light guides is anchored on base and the other one is attached to inertial mass. Peculiarity of element lies in manufacture of immobile base and mobile inertial mass from one profiled monolithic plate. Inertial mass includes two beams as minimum each one separated from immobile base by through holes, having groove running along beam and carrying receiving mobile light guide fixed in it. Transmitting fibrous light guide is located on immobile base and is positioned in groove cut in immobile base uniaxially to groove of beam. Cuts of different depth are made in each beam close to its base and perpendicular to its longitudinal axis. Another peculiarity of element consists in arrangement of beams with different orientation in space. EFFECT: improved adaptability to manufacture, enhanced sensitivity and measurement precision. 1 cl, 2 dwg
