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5310M1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，工作溫度高達260℃，適用于環境應力篩選和高加速壽命測試。
The Dytran 5310M1 is a high temperature vibration measurement system designed for use in Environmental Stress Screening (ESS) and Highly Accelerated Life Testing and Highly Accelerated Stress Screening (HALT/HASS). The system combines (1) model 3030C1 high temperature charge mode accelerometer, (1) model 6019B10 low noise 10-foot cable assembly (10-32 to BNC) and (1) model 4705M13 in-line charge amplifier.
Due to its rugged, lightweight, hermetically sealed design, all stainless steel construction, and reliable high temperature operation to +500°F (+260°C), the Dytran model 3030C1 high temperature sensor has because the industry’s charge mode accelerometer of choice for test laboratory environments.
