產品簡介
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(xiàn)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(tài)，這種現(xiàn)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(xiàn)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(shù)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(jié)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(tǒng)、牽引控制系統(tǒng)等安全性能方面。
美國Dytran的3443C是一款高溫型三軸加速度傳感器/振動傳感器，具有體積小、結構堅固，高密封、耐高溫等特點，高頻率，工作溫度高達260℃，適用于發(fā)動機振動研究和振動監(jiān)測。
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.
