压电式加速度传感器,又称振动传感器,是基于压电晶体的压电效应工作的。某些晶体在一定方向上受力变形时,其内部会产生极化现象,同时在它的两个表面上产生符号相反的电荷;当外力去除后,又重新恢复到不带电状态,这种现象称为“压电效应",具有“压电效应"的晶体称为压电晶体。常用的压电晶体有石英、压电陶瓷等,在现代生产生活中被应用于许许多多的方面,如手提电脑的硬盘抗摔保护,目前用的数码相机和摄像机里,也有加速度传感器,用来检测拍摄时候的手部的振动,并根据这些振动,自动调节相机的聚焦。压电加速度传感器还应用于汽车安全气囊、防抱死系统、牵引控制系统等安全性能方面。

 

美国Dytran的3235C1是一款高温型加速度传感器/振动传感器,具有体积小、结构坚固,高密封、耐高温等特点,灵敏度50pC/g,工作温度高达+287℃。

The Dytran 3235C1 is a high temperature differential output accelerometer, offering extreme stability over a wide operating temperature range. Offered with a 50 pC/g sensitivity, model 3235C1 is unique in that it offers high charge sensitivity while simultaneously offering a balanced differential output.

 

Featuring a transverse mounted glass-to-metal sealed 2-pin radial connector and an industry standard tri-bolt mount, the Dytran model 3235C1 can reliably operate in temperatures up to +550°F (+287°C). Accelerometers are packaged in a stainless steel housing, hermetically sealed for reliable operation in high humidity and dirty environments, and case isolated to avoid EMI/ground loop interference.
