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3030C1是一款高溫型加速度傳感器/振動(dòng)傳感器,專為環(huán)境應(yīng)力篩選、高強(qiáng)化和高加速壽命試驗(yàn)而設(shè)計(jì),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)260攝氏度,是實(shí)驗(yàn)室檢測(cè)中心的。
The Dytran 3030C1 is known as the industry workhorse for Environmental Stress Screening (ESS) and Highly Accelerated Life Testing and Highly Accelerated Stress Screening (HALT/HASS). Because of its rugged, lightweight, hermetically sealed design, all stainless steel construction, and reliable high temperature operation to +500°F (+260°C), the Dytran model 3030C1 has become the industry's charge mode accelerometer of choice for test laboratory environments.
