Mini Triax Accelerometers Target Space-constrained Apps
Well-suited for use in applications where space is at a premium, the 3023M20 miniature triaxial accelerometer from Dytran Instruments weighs only 2.4g with a vertical dimension of 0.28". Using the latest in quartz shear technology coupled with two-wire internal IEPE electronics, the device contains three miniature quartz laminar shear mode accelerometer elements mounted orthogonally to each other so that they can measure the complete motion of a point welded into a titanium housing. 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. Priced at $1,050.
