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(yīng)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(dāng)外力去除后，又重新恢復(fù)到不帶電狀態(tài)，這種現(xiàn)象稱為“壓電效應(yīng)"，具有“壓電效應(yīng)"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(yīng)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(diào)節(jié)相機的聚焦。壓電加速度傳感器還應(yīng)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3035C是一款壓電式高溫型加速度傳感器/振動傳感器，具有體積小，結(jié)構(gòu)堅固，高密封，耐高溫等特點，重2.5g，不銹鋼結(jié)構(gòu)，工作溫度高達204攝氏度。

The Dytran 3035C is a piezoelectric charge mode accelerometer with sensitivity of 2.5 pC/g, and is ideal for high temperature applications where vertical space is limited. This miniature sensor has a height of just 0.33 inches (8.4 millimeters) and weighs just 2.5 grams, making it ideal for use in applications where mass loading is a concern. In addition, the Dytran model 3035C features a hermetically sealed, stainless steel construction and a 5-44 radial connector.

This sensor is part of Dytran's 3035C series of charge mode accelerometers, which differ only in their type of mounting configuration. Model 3035C features a 5-40 stud mount, while model 3035CG utilizes adhesive mounting capabilities.
