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，其內部會產生極化現象，同時在它的兩個表面上產生符號相反的電荷；當外力去除后，又重新恢復到不帶電狀態，這種現象稱為“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，在現代生產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，并根據這些振動，自動調節相機的聚焦。壓電加速度傳感器還應用于汽車安全氣囊、防抱死系統、牽引控制系統等安全性能方面。
美國Dytran的3196C是一款高溫型加速度傳感器/振動傳感器，工作溫度高達260攝氏度，結構堅固，不銹鋼金屬外殼，應對工作環境。
The Dytran 3196C is a high temperature charge mode accelerometer, designed to reliably operate in temperatures up to +500°F (+260°C). Featuring a nominal sensitivity of 8 pC/g, hermetic sealing, and a rugged stainless steel construction, the model 3196C is expressly designed for use in extreme environments. Units are offered with an industry standard tri-bolt mount and radial TNC connector.
