THREE-COMPONENT PIEZOELECTRIC ACCELEROMETER Russian patent published in 2023 - IPC G01P15/09 

FIELD: measuring technology.

SUBSTANCE: invention relates to the field of measuring technology. A three-component piezoelectric accelerometer contains a housing with three piezoelectric elements, the sensitivity axes of which are mutually perpendicular, a through hole is made in the housing for fixing the piezoelectric accelerometer on the test object, while two through holes are additionally made in the housing, while the symmetry axes of all holes are mutually perpendicular to each other, coincide with the sensitivity axes of the piezoelectric elements and have a common point of intersection.

EFFECT: invention provides the possibility of fixing (re-fixing) a three-component piezoelectric accelerometer on mutually perpendicular surfaces of the test object without changing the position of the accelerometer in space while realizing the possibility of simultaneously measuring three components of the acceleration vector at one point.
