3133D Series – Miniature Accelerometer for Product Development Testing

Dytran Instruments, Inc., a leading manufacturer of piezoelectric and DC MEMS accelerometers, dynamic force and pressure sensors, cables, and associated electronics, presents the series 3133D, ultra miniature hermetically sealed IEPE triaxial accelerometers.

Today's electronic devices continue to decrease in size yet require more development testing than ever before. Series 3133D is characterized by its miniature size (.24" L X .24" W X .23" H) 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 Dytran Series 3133D 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.

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.

Unique features of the 3133D series include its low frequency response and low base strain sensitivity. 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.
