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，用來檢測拍攝時(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Dytran的5310M1是一款高溫型加速度傳感器/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)，工作溫度高達(dá)260℃，適用于環(huán)境應(yīng)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.
