    壓電式加速度傳感器，又稱振動(dòng)傳感器,，是基于壓電晶體的壓電效應(yīng)工作的,。某些晶體在一定方向上受力變形時(shí)，其內(nèi)部會(huì)產(chǎn)生極化現(xiàn)象，同時(shí)在它的兩個(gè)表面上產(chǎn)生符號(hào)相反的電荷,；當(dāng)外力去除后,，又重新恢復(fù)到不帶電狀態(tài)，這種現(xiàn)象稱為“壓電效應(yīng)”,，具有“壓電效應(yīng)”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(chǎn)生活中被應(yīng)用于許許多多的方面,，如手提電腦的硬盤抗摔保護(hù)，目前用的數(shù)碼相機(jī)和攝像機(jī)里,，也有加速度傳感器,，用來(lái)檢測(cè)拍攝時(shí)候的手部的振動(dòng)，并根據(jù)這些振動(dòng),，自動(dòng)調(diào)節(jié)相機(jī)的聚焦,。壓電加速度傳感器還應(yīng)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(guó)Dytran的3274A1是一款超小型IEPE加速度傳感器/振動(dòng)傳感器，IEEE1451.2是智能傳感器接口模塊標(biāo)準(zhǔn),。它提供了將傳感器和變送器連接到網(wǎng)絡(luò)的接口標(biāo)準(zhǔn),，主要用于實(shí)現(xiàn)傳感器的網(wǎng)絡(luò)化。IEEE1451.2標(biāo)準(zhǔn)采用通用的A/D或D/A轉(zhuǎn)換裝置作為傳感器的I/O接口,，將各種傳感器模擬量轉(zhuǎn)換成標(biāo)準(zhǔn)規(guī)定格式的數(shù)據(jù),，連同一個(gè)小存儲(chǔ)器—傳感器電子數(shù)據(jù)表TEDS（Transducer Electronic Data Sheet），與標(biāo)準(zhǔn)規(guī)定的處理器目標(biāo)模型—網(wǎng)絡(luò)適配器NCAP（Network Capable Application Process）連接,。如此,，數(shù)據(jù)可以按網(wǎng)絡(luò)規(guī)定的協(xié)議接入網(wǎng)絡(luò)。該標(biāo)準(zhǔn)結(jié)構(gòu)模型提供了一個(gè)連接智能變送器的接口模型STIM（Smart Transducer Interface Module）NCAP的10線標(biāo)準(zhǔn)接口—變送獨(dú)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.
