Miniature Triaxial Accelerometer

The model 3023M20 miniature triaxial accelerometer is ideal for use in applications where space is at a premium. It uses the latest in quartz shear technology coupled with 2-wire internal IEPE electronics. Since its vertical dimension is only 0.28 inches, model 3023M20 mounts with adhesives into very small space. It weighs only 2.4 grams.

This instrument contains three miniature quartz laminar shear mode accelerometer elements mounted to a single support and welded into a titanium housing. The three elements are mounted orthogonally to each other so that they can measure the complete motion of a point.

The IEPE design means that three miniature IC amplifiers are built into the instrument, one for each axis, to lower the impedance of the quartz seismic elements by many orders of magnitude. This technique allows the driving of long cables without affecting sensitivity and the use of very simple constant current type power units.
