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3030C1是一款高温型加速度传感器/振动传感器,专为环境应力筛选、高强化和高加速寿命试验而设计,具有体积小,结构坚固,高密封,耐高温等特点,最大工作温度高达260摄氏度,是实验室检测中心的不二之选。
The Dytran 3030C1 is known as the industry workhorse for Environmental Stress Screening (ESS) and Highly Accelerated Life Testing and Highly Accelerated Stress Screening (HALT/HASS). Because of its rugged, lightweight, hermetically sealed design, all stainless steel construction, and reliable high temperature operation to +500°F (+260°C), the Dytran model 3030C1 has become the industry's charge mode accelerometer of choice for test laboratory environments.
