壓電式加速度傳感器，又稱振動(dòng)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(shí)，其內(nèi)部會(huì)產(chǎn)生極化現(xiàn)象，同時(shí)在它的兩個(gè)表面上產(chǎn)生符號(hào)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(hù)，目前用的數(shù)碼相機(jī)和攝像機(jī)里，也有加速度傳感器，用來(lái)檢測(cè)拍攝時(shí)候的手部的振動(dòng)，并根據(jù)這些振動(dòng)，自動(dòng)調(diào)節(jié)相機(jī)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(guó)Dytran的3049D是一款高溫型加速度傳感器/振動(dòng)傳感器，專具有體積小，結(jié)構(gòu)堅(jiān)固，高密封，耐高溫等特點(diǎn)，工作溫度高達(dá)177攝氏度，鈦合金外殼，靈敏度5.8 pC/g

The Dytran 3049D is a rugged high temperature charge mode accelerometer, designed to reliably operate in temperatures up to +350°F (+177°C). Featuring a lightweight titanium housing and a sensitivity of 5.8 pC/g, the base of the model 3049D is electrically isolated to avoid EMI/ground loop interference. Units are also hermetically sealed for use in demanding environments.

This sensor is part of Dytran's 3049D piezoelectric accelerometer series, which differ only in terms of their mounting configuration. The model 3049D features a 10-32 mounting stud, while its counterpart, the model 3049D1, is offered with adhesive mounting capabilities.
