在工業(yè)自動控制、汽車、地震測量、軍事和空間系統(tǒng)等領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具有高的諧振頻率，動態(tài)性能要好，以保證快速、準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技術與微電子技術成果研制而成,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)境適應性強等特點。美國Dytran的3086A1是一款IEPE沖擊型加速度傳感器，適用于量程達70000g 以上的沖擊加速度參數(shù)測量與控制。

The Dytran 3086A1 is a highly rugged IEPE accelerometer with a very high natural frequency of 100 kHz, designed to measure severe shocks and other extreme short duration events. High shock measurement requirements are typically characterized as such above 2,500g'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, the Dytran 3086A1 features a quartz crystal sensing element, operating in compression mode, housed in a hermetically sealed lightweight titanium housing, for a total weight of just 3.5 grams. Units are electrically base isolated and feature a 1/4-28 mounting stud and axial mounted solder pins for cable connection. This particular connector style aims in eliminating discontinuities during high g events and reduces connector stresses. The unique mounting configuration of the Dytran model 3086A1 allows for use of a field replaceable cable assembly (sold separately).
