(ZH) 加速度测量仪和用于制造这种加速度测量仪的方法
Abstract: front page image
(EN) The invention relates to an acceleration measuring device (1) comprising a piezoelectric system (2), a seismic mass (3), and a base plate (4); during an acceleration, the seismic mass (3) applies a force, which is proportionate to the acceleration thereof, to the piezoelectric system (2), said force generates piezoelectric charges in the piezoelectric system (2), and said piezoelectric charges canbe electrically picked up as acceleration signals; the seismic mass (3) includes two mass elements (30, 30'); positive piezoelectric charges can be electrically picked up as acceleration signals on afirst mass element (30), and negative piezoelectric charges can be electrically picked up as acceleration signals on a second mass element (30').
(ZH) 本发明涉及一种加速度测量仪(1),其具有压电系统(2)、振动质量(3)和基板(4);在加速期间,振动质量(3)将与它的加速度成比例的力施加到压电系统(2)上,所述力在所述压电系统(2)中产生压电电荷,并且所述压电电荷能够作为加速度信号被电量取,其中,振动质量(3)具有两个质量元件(30,30');其中,正压电电荷能够在第一质量元件(30)上作为加速度信号被电量取;并且其中,负压电电荷能够在第二质量元件(30')上作为加速度信号被电量取。
