ACCELEROMETER WITH CONVERTERS BASED ON SURFACE ACOUSTIC WAVE Russian patent published in 1999 - IPC

FIELD: measurement technology. SUBSTANCE: given accelerometer has plate so bent that it forms three mutually orthogonal faces of cube. There are manufactured six acoustic lines, two on each face. Twelve generators based on effect of surface acoustic wave are placed in twos on both surfaces of each acoustic line. Increased precision and expanded functional capabilities of accelerometer are provided thanks to elimination of cross coupling between measurement channels of different projections of measured acceleration and to putting plate with acoustic lines into form of three mutually orthogonal faces of cube. EFFECT: increased precision and expanded functional capabilities of accelerometer. 1 dwg
