Description
го усили измен етс амплитуда механических колебаний пЪезоэлемента и, соответственно , разность потенциалов на выходной системе электродов, котора вл етс мерой измер емого усили . Шары 2 .заключены в сепаратор 3 так, что они имеют две степени свободы в плоскости, параллельной гран м пъезоэлемента. Крома того, сепаратор фиксирует шары 2 отThis force changes the amplitude of the mechanical oscillations of the piezoelectric element and, accordingly, the potential difference at the output electrode system, which is a measure of the measured force. Balls 2 are enclosed in separator 3 so that they have two degrees of freedom in a plane parallel to the faces of the piezoelectric element. In addition, the separator fixes the balls 2 from

Таким образом, в предлагаемом устройстве за счёт точечного приложени измер емого усили к пьезоэлементу свеI дена к минимуму площадь акустического контакта между колеблющимис поверх иост ми; пъезоэлемента и демпфирующимиThus, in the proposed device, due to the point application of the measured force to the piezoelectric element, the area of acoustic contact between oscillating surfaces is minimized; piezoelectric element and damping
