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3224C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，灵敏度0.6 pC/g，工作温度高达177℃。

The Dytran 3224C is an ultra miniature, low profile piezoelectric charge mode accelerometer with a sensitivity of 0.6 pC/g designed to adhesively mount in spaces inaccessible to other types of accelerometers. The sensor features an overall height of just 0.10 inches (2.6 millimeters) and an overall weight of just 0.2 grams.

Designed to reliably operate in high temperatures up to +350°F (+177°C), the Dytran model 3224C incorporates a ceramic shear sensing element packaged in a lightweight laser welded titanium housing, with a three foot integral cable terminating to a 10-32 jack. The cable is designed to mate with several Dytran extension cables.

Due to its small size and lightweight, the model 3224C is ideal for the measurement of shock and vibration of very small objects such as printed circuit boards ad board-mounted components.
