Dytran Instruments, Inc. is pleased to introduce a new miniature triaxial industrial accelerometer that is ideal for use in applications where space is at a premium. The 3023M20 uses the latest in quartz shear technology coupled with 2-wire internal IEPE electronics. Model 3023M20 mounts with professional adhesives into very small spaces since its vertical dimension is 0.28 in. 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 professional 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.
