在工業(yè)自動控制、汽車、地震測量、軍事和空間系統(tǒng)等領(lǐng)域中的許多場合都是用沖擊加速度傳感器，由于受工作環(huán)境的限制，要求沖擊加速度傳感器應(yīng)具有高的諧振頻率，動態(tài)性能要好，以保證快速、準(zhǔn)確測試出被測對象的沖擊力或沖擊加速度。
沖擊加速度傳感器，采用MEMS技術(shù)與微電子技術(shù)成果研制而成,集加速度傳感器、信號變換器、電源變換器、信號濾波電路、飽和控制與溫度補(bǔ)償于一體,具有微體積、微功耗、微噪聲、高集成、高穩(wěn)定、高可靠、低溫漂、環(huán)境適應(yīng)性強(qiáng)等特點(diǎn)。美國Dytran的3200B是一款I(lǐng)EPE沖擊型加速度傳感器，結(jié)構(gòu)堅(jiān)固，尺寸小，適用于量程達(dá)70000g 以上的沖擊加速度參數(shù)測量與控制。
The Dytran 3200B is a highly rugged IEPE accelerometer with a natural frequency greater than 90 kHz, designed to measure severe shocks and other extreme short duration events. High shock measurements are typically characterized as such above the range of 2,500 g's. In order to accurately measure shock levels of this magnitude, accelerometers must have a high natural frequency, rugged construction and be fairly compact in size.
Available with a 70,000g range, Dytran 3200B features a quartz crystal sensing element, operating in compression mode, packaged in a stainless steel housing for a total weight of 6 grams. Units are electrically base isolated and feature a broad frequency response, 1/4-28 mounting stud and 10-32 axial connector.
