壓電式加速度傳感器又稱壓電加速度計(jì)。它也屬于慣性式傳感器。壓電式加速度傳感器的原理是利用壓電陶瓷或石英晶體的壓電效應(yīng),在加速度計(jì)受振時(shí),質(zhì)量塊加在壓電元件上的力也隨之變化。當(dāng)被測(cè)振動(dòng)頻率遠(yuǎn)低于加速度計(jì)的固有頻率時(shí),則力的變化與被測(cè)加速度成正比。
The Dytran 7523A1 is a triaxial DC response accelerometer, designed to offer a simple and cost effective solution for low level, low frequency vibration measurements. Tailored for zero-to-medium frequency applications, the Dytran model 7523A1 has a low end frequency response of 0 Hz and an upper frequency range of 1,500 Hz, with a total weight of just 10 grams.
