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3220C1是一款高溫型加速度傳感器/振動傳感器，具有體積小、結構堅固，高密封、耐高溫等特點，鈦合金金屬外殼，工作溫度高達260℃。
The Dytran model 3220C1 is a low profile piezoelectric charge mode accelerometer with lightweight titanium construction. The distinguishing feature of the model 3220C1 is its unique miniature thru hole mounting configuration, which allows the sensor to be turned a full 360° prior to securing. Electrical connection for the model 3220C1 is achieved via a coaxial glass-to-metal sealed 5-44 connector.
The model 3220C1 is offered with a sensitivity of 10 pC/g and features a ceramic sensing element operating in shear mode. Units also have a low overall weight of just 4.0 grams, making them ideal for applications where mass loading is a concern. Units are hermetically sealed to avoid contamination in high humidity and dirty environments and base isolated to avoid EMI/ground loop interference.
