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工作的。某些晶體在一定方向上受力變形時,其內部會產生極化現象,同時在它的兩個表面上產生符號相反的電荷;當外力去除后,又重新恢復到不帶電狀態,這種現象稱為“壓電效應",具有“壓電效應"的晶體稱為壓電晶體。常用的壓電晶體有石英、壓電陶瓷等,在現代生產生活中被應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,并根據這些振動,自動調節相機的聚焦。壓電加速度傳感器還應用于汽車安全氣囊、防抱死系統、牽引控制系統等安全性能方面。
美國Dytran的3092C是一款高溫型加速度傳感器/振動傳感器,不銹鋼結構,高密封,工作溫度高達485攝氏度,在嚴苛的工作環境下仍性能可靠。
The Dytran 3092C is a piezoelectric charge mode accelerometer capable of operating at temperatures up to +900°F (+482°C). For reliable performance under harsh conditions, units are hermetically sealed and housed in a stainless steel construction.
Featuring a compact, robust design as an accompaniment to its ultra high temperature operation, model 3092C is offered with a sensitivity of 3.5 pC/g, 10-32 stud mounting capabilities and a 10-32 radial connector.
