產(chǎn)品簡介
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(yīng)工作的。某些晶體在一定方向上受力變形時，其內(nèi)部會產(chǎn)生極化現(xiàn)象，同時在它的兩個表面上產(chǎn)生符號相反的電荷；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，用來檢測拍攝時候的手部的振動，并根據(jù)這些振動，自動調(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3152C2是一款高溫型加速度傳感器/振動傳感器，具有體積小，結(jié)構(gòu)堅固，高密封，耐高溫等特點，工作溫度高達(dá)500°F。
The Dytran 3152C2 is a high temperature piezoelectric charge mode accelerometer, featuring an axial mounted 10-32 electrical connector and 10-32 tapped mounting hole. With a 0.5 inch (12.7 millimeter) hex size, the accelerometer is small enough to mount in a multitude of space constrained environments. Model 3152C2 has a sensitivity of 4 pC/g, robust stainless steel housing and features a rugged hermetically sealed construction for use in demanding environments.
