New Air Bearing Shaker Simplifies Accelerometer Calibration

THE MODAL SHOP, INC. has introduced a new calibration grade air bearing shaker, Model 394A30.

The Model 394A30’s unique suspension system virtually eliminates transverse lateral motion – providing an air cushion – and adjusts easily to calibrate a range of accelerometer sizes.  No more rubber bands.  This allows for more accurate and efficient results, particularly in rugged, frequent day-to-day use, as well as faster calibration cycle times versus other air bearing shakers.  Utilizing a mechanical spring armature design, traditional electromechanical shakers have the physical limitation of introducing transverse movement into the measurement.

The shaker is primarily used in accelerometer calibration systems such as the TMS 9155C Accelerometer Calibration Workstation.
