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3274A1是一款超小型IEPE加速度传感器/振动传感器，IEEE1451.2是智能传感器接口模块标准。它提供了将传感器和变送器连接到网络的接口标准，主要用于实现传感器的网络化。IEEE1451.2标准采用通用的A/D或D/A转换装置作为传感器的I/O接口，将各种传感器模拟量转换成标准规定格式的数据，连同一个小存储器—传感器电子数据表TEDS（Transducer Electronic Data Sheet），与标准规定的处理器目标模型—网络适配器NCAP（Network Capable Application Process）连接。如此，数据可以按网络规定的协议接入网络。该标准结构模型提供了一个连接智能变送器的接口模型STIM（Smart Transducer Interface Module）NCAP的10线标准接口—变送独立接口TII（Transducer Independence Interface）。

The Dytran 3274A1 is an ultra miniature high frequency IEPE accelerometer with IEEE 1451.4 TEDS capabilities.

Units have an overall height of just 0.24-inches (6.1-millimeters), weigh just 2 grams, and are ideal for the measurement of shock and vibration of very small, lightweight objects such as printed circuit boards and board mounted components.

Offered with a sensitivity of 5 mV/g, the model 3274A1 features a quartz shear sensing element, packaged in a lightweight, teardrop titanium housing. Designed for adhesive mount, the Dytran model 3274A1 has an upper frequency response of 10,000 Hz. Due to their low mass and high crystal stiffness, units have a resonant frequency of >40 kHz, allowing them to be used to measure high frequency vibration with very little error.

The model 3274A1 utilizes a specially designed 3-56 coaxial connector, mating with a 3-foot (0.9-meter) replaceable coaxial cable and terminating to a 10-32 jack. Units are hermetically sealed for reliable operation in high humidity environments, as well as case isolated to avoid EMI/ground loop interference.
