The Dytran Series 3133D, distributed by disynet is characterized by its miniature size 6.1mm x 6.1mm x 5.9mm) which allows it to be mounted in spaces that are inaccessible to other types of triaxial accelerometers. It features a hermetically sealed titanium case to aid in moisture resistance and weighs only 0.8 grams. The series is offered with a sensitivity that ranges from 0.25mV/g to 10mV/g and utilizes adhesive mounting capabilities. It features a permanently attached 3 ft. long coaxial cable with a 4-pin connector and is designed to mate with several models of extension cables for connection to IEPE power sources.
High frequency vibration measurement
In each of the three orthogonal axes, the instruments generate an electrostatic charge mode signal by stressing a "planar shear" type of self generating crystal element. This series has very low mass and high crystal stiffness which allows the accelerometers to have a resonant frequency greater than 27 kHz. As a result, it can be used to measure high frequency vibrations with very little error. A TEDS version of this series is also available for customers who need plug and play identification.
The components (adhesives, cables, ...) of the sensor - especially for use in the aerospace industry - were designed for low outgassing behavior. Moreover, series 3133D is ideal for shock and vibration testing of small, lightweight specimens such as printed circuit boards, board-mounted components and other miniature products. It is capable of operating in a variety of application environments including Environmental Stress Screening (ESS), HALT/HASS, modal and structural analysis, product response testing and general purpose triaxial vibration testing.
