SHOCK ACCELERATION SENSOR Russian patent published in 2009 - IPC G01P15/04 

FIELD: physics, measurement.

SUBSTANCE: invention is related to metering equipment and is intended for measurement of shock acceleration. Sensor comprises body 2, axis 1 fixed in body with the possibility of rotation 1, in which bulges 4 are arranged, and inertial elements that contact with them, while each one is made in the form of unbalanced lever 5 fixed in body with the possibility of rotation on additional axis, and it point for contact with appropriate bulge is installed in plane passing through axis centre, rod 10 of actuating mechanism 11 and anchor 7 fixed to axis, and anchor is installed in slots of permanent magnet poles, besides, three bulges are arranged from one axis end, and three - symmetrically from the other one. Protrusions are arranged evenly around axis and at an equal distance from it and each other, and every unbalanced lever is installed parallel to axis between appropriate symmetrical protrusions, besides, mass center of each unbalanced lever is located in plane, which is inclined to plane that passes through axis center and contact point at an angle of 31°-37°.

EFFECT: higher accuracy of actuation with simultaneous simplification of design and reduction of dimensions.
