美国DT 3086A1冲击型加速度传感器

概述

The Dytran 3086A1 is a highly ru*ed IEPE accelerometer with*ery high natural frequency of 100 kHz, designed to measure severe shocks and other extreme short duration events. High shock measureme*equirements are typically characterized as such above 2,500g's. In order to accurately measure shock levels of thi*agnitude, accelerometer*ust h*e a high natural frequency, ru*ed c*truction and be fairly compact in size.

Available with a 70,000g range, the Dytran 3086A1 features a quartz crystal sensing eleme*perating 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. Thi*rticular 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).
