Start Vibration Exciter
APS Vibration Exciters

APS Dynamics Inc. designs and manufactures mainly Long Stroke Vibration Exciters for the low frequency range. Three main designs of the  ELECTRO-SEIS® shakers are available


The ball bearing shakers are used primarily for modal test excitation or environmental test applications in the low frequency range < 200 Hz. Although these shakers have a long stroke (158 mm) they are still portable. Thus APS ELECTRO-SEIS® shaker are ideal tools for testing of bridges, buildings or other objects outside a laboratory.

APS_113AB_129_500For sensor calibration applications or testing applications that require a smooth motion of the exciter, the APS Shakers feature air bearing armature guidance for exceptionally clean waveforms with wide dynamic range and very low cross-axis motion.
