PIEZOELECTRIC ACCELEROMETER Russian patent published in 2007 - IPC G01P15/09 

FIELD: measuring equipment, applicable for use in measurement and monitoring facilities of vibroacceleration of various machines and mechanisms.

SUBSTANCE: the piezoelectric accelerometer has a multilayer stack of piezoelectric plates consisting of three sections. The sections comprise groups of three plates. The extreme plates in a group are provided with diametric slots filled with switching buses. One of the middle plates is fully polarized in thickness, the other two middle plates have segments polarized in thickness in the opposite directions. The sections with segmented plates are turned one relative to the other through 90 deg. about the stack longitudinal axis.

EFFECT: expanded functional potentialities due to measurement of vibroacceleration in three mutually perpendicular directions.
