壓電式加速度傳感器，又稱振動傳感器，是基于壓電晶體的壓電效應工作的。某些晶體在一定方向上受力變形時，其內(nèi)部會產(chǎn)生極化現(xiàn)象，同時在它的兩個表面上產(chǎn)生符號相反的電荷；當外力去除后，又重新恢復到不帶電狀態(tài)，這種現(xiàn)象稱為“壓電效應"，具有“壓電效應"的晶體稱為壓電晶體。常用的壓電晶體有石英、壓電陶瓷等，在現(xiàn)代生產(chǎn)生活中被應用于許許多多的方面，如手提電腦的硬盤抗摔保護，目前用的數(shù)碼相機和攝像機里，也有加速度傳感器，用來檢測拍攝時候的手部的振動，并根據(jù)這些振動，自動調節(jié)相機的聚焦。壓電加速度傳感器還應用于汽車安全氣囊、防抱死系統(tǒng)、牽引控制系統(tǒng)等安全性能方面。

美國Dytran的3224C是一款高溫型加速度傳感器/振動傳感器，具有體積小、結構堅固，高密封、耐高溫等特點，靈敏度0.6 pC/g，工作溫度高達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.
