概述
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 responsemounting stud and 10-32 axial connector.
