CONVERTER OF LINEAR ACCELERATIONS Russian patent published in 2009 - IPC G01P15/11 

FIELD: instrument making.

SUBSTANCE: invention relates to data processing and measuring hardware, particularly, to appliances designed to indicate and control, in time, the 2^nd derivative of flying vehicle velocity. The proposed converter comprises a hollow cylindrical magnetic circuit consisting of two symmetric parts made of magnetically soft material and coupled via diamagnetic gasket. It comprises also the casing, a screen encased therein and furnished with rectangular inner pole. Aforesaid pole accommodates the ring made of diamagnetic material, two windings arranged nearby the magnetic circuit base and coupled by inner ferromagnetic core. It accommodates also a movable element representing a ring representing made from radially magnetised magnet. The height of aforesaid magnet equals the height of an inner circular pole that envelopes the said magnetic circuit ferromagnetic core. Aforesaid movable element incorporates additional ring radially magnetised in opposite direction. Note here that both rings are made from permanent magnets and separated by a non-magnetic gap, i.e. diamagnetic non-conducting washer, its width being equal to that of aforesaid washer.

EFFECT: higher accuracy of measurement, sensitivity and slope of converting characteristic.
