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.

 

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).
