压电式加速度传感器,又称振动传感器,是基于压电晶体的压电效应工作的。某些晶体在一定方向上受力变形时,其内部会产生极化现象,同时在它的两个表面上产生符号相反的电荷;当外力去除后,又重新恢复到不带电状态,这种现象称为“压电效应",具有“压电效应"的晶体称为压电晶体。常用的压电晶体有石英、压电陶瓷等,在现代生产生活中被应用于许许多多的方面,如手提电脑的硬盘抗摔保护,目前用的数码相机和摄像机里,也有加速度传感器,用来检测拍摄时候的手部的振动,并根据这些振动,自动调节相机的聚焦。压电加速度传感器还应用于汽车安全气囊、防抱死系统、牵引控制系统等安全性能方面。
美国Dytran的3152C2是一款高温型加速度传感器/振动传感器,具有体积小,结构坚固,高密封,耐高温等特点,工作温度高达500°F。
The Dytran 3152C2 is a high temperature piezoelectric charge mode accelerometer, featuring an axial mounted 10-32 electrical connector and 10-32 tapped mounting hole. With a 0.5 inch (12.7 millimeter) hex size, the accelerometer is small enough to mount in a multitude of space constrained environments. Model 3152C2 has a sensitivity of 4 pC/g, robust stainless steel housing and features a rugged hermetically sealed construction for use in demanding environments.
