Dytran Instruments, Inc. (www.dytran.com) a leading manufacturer of piezoelectric and DC MEMS accelerometers, force and pressure transducers and associated electronics, is pleased to announce the release of series 3493A, our innovative ultra miniature, low noise, IEPE triaxial accelerometers.
Dytran Series 3493A is characterized by its miniature size (.30 L X .24 W X .26" H) which allows it to be mounted in spaces that are inaccessible to other types of triaxial accelerometers. It utilizes a J-FET amplifier, demonstrating a considerably lower noise floor (and therefore better resolution) than MOSFET-based IEPE devices. Improved signal-to-noise ratio makes it ideal for applications where very low vibration amplitudes are being measured and maximum resolution is required.
In each of the three orthogonal axes, the instrument generates a voltage proportional to vibration by stressing a "planar shear" type, self-generating crystal element structure inside the sensor housing. The 3493A has very low mass and high crystal stiffness which allows the accelerometer to have a resonant frequency greater than 30 kHz. As a result, it can be used to measure high frequency vibration with very little error.
Series 3493A is packaged in a titanium case and weighs only 0.9 grams. Models are available in two sensitivities (5mV/g and 10mV/g) and are installed using adhesives or mounting wax. This series features an integral multi conductor, shielded cable design terminated with a 4-pin, ¼-28 threaded connector designed to mate with several models of extension cables for connection to IEPE power sources.
Typical uses for series 3493A include but are not limited to the following test applications: shock and vibration testing of small lightweight specimens (such as printed circuit boards), product response testing, modal & structural analysis and general purpose triaxial vibration testing.
