Series 3133D Miniature IEPE Triaxial Accelerometer

Product Announcement from Dytran Instruments, Inc.

Dytran Instruments has introduced the 3133D series, an ultra miniature IEPE three-axis piezoelectric family of low profile, voltage mode accelerometers that meets the demand for a small size, low mass, accelerometer for HALT/HASS, drop test, vibration, survivability and end of line product testing. Weighing just 0.8 grams, series 3133D is characterized by its miniature size which allows it to be mounted in spaces that are inaccessible to other types of triaxial accelerometers.

It features low outgassing characteristics and a hermetically sealed titanium case to aid in moisture resistance. The Dytran Series 3133D is offered with a sensitivity that ranges from 0.7mV/g to 10mV/g and is designed with adhesive mounting capabilities.  It features a permanently mounted 3 ft. long coaxial cable that has 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 these instruments 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.

Key Features:

  • Temperature range: -67° to +320°F
  • Low base strain sensitivity
  • Ideal low frequency response
  • TEDS version also available
  • Hermetically sealed
  • Adhesive mount
  • 0.8 grams
  • Titanium
  • Triaxial
  • IEPE
