摘要
FIELD: measurement technology. SUBSTANCE: piezoelectric element is made in form of rectangular parallelepiped fixed onto the basic base. Polar axis of the piezoelectric element is perpendicular to its plane of fixing. Rectangular parallelepiped is made of piezoelectric ceramics or monocrystal with dielectric permeability ε 500; it has square-shaped base. Height h of rectangular parallelepiped in relation to length b of side of the square is chosen from 0,3, h/b 1,2 relation. Array of piezoelectric modules is presented in form of . EFFECT: improved precision of measurement. 2 cl, 1 tbl, 4 dwg
