壓電式加速度傳感器，又稱(chēng)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(chēng)為“壓電效應(yīng)"，具有“壓電效應(yīng)"的晶體稱(chēng)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(pán)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(chē)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3443C是一款高溫型三軸加速度傳感器/振動(dòng)傳感器，具有體積小、結(jié)構(gòu)堅(jiān)固，高密封、耐高溫等特點(diǎn)，高頻率，工作溫度高達(dá)260℃，適用于發(fā)動(dòng)機(jī)振動(dòng)研究和振動(dòng)監(jiān)測(cè)。
The Dytran 3443C is a triaxial, charge mode vibration monitoring accelerometer, designed to reliably operate in temperatures up to +500°F (+260°C).
Ideal for use in a variety of vibration monitoring applications including engine vibration studies, exhaust system analysis and industrial vibration monitoring, Dytran’s model 3443C high temperature accelerometer is capable of operating under extreme temperatures, while at the same time providing the high levels of reliability, durability and accuracy that is offered with standard laboratory sensors. Weighing just 10 grams, the Dytran model 3443C features ceramic shear sensing elements mounted in a hermetically sealed, lightweight titanium housing. Units utilize (2) thru holes for mounting and (3) 10-32 radial connectors.
