概述

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.

在工业自动控制、汽车、地震测量、军事和空间系统等领域中的许多场合都是用冲击加速度传感器，由于受工作环境的限制，要求冲击加速度传感器应具有高的谐振频率，动态性能要好，以保证快速、准确测试出被测对象的冲击力或冲击加速度。

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).
