Low Frequency Excitation Device APS Series
Low Frequency Vibration Exciter Device APS Series
This is a low-frequency vibration exciter from the German company SPEKTRA, a specialized manufacturer of calibration devices for vibration and acoustic sensors. The APS series provides excitation at ultra-low frequencies for seismic measurements and achieves large amplitude strokes, allowing for the verification of the response of low-frequency accelerometers necessary for vibration analysis of structures in the fields of seismic resistance, vibration control, and isolation. Additionally, its application range is extensive, including modal analysis in transportation systems such as automobiles and aircraft, as well as in the electronics field. It is a secondary calibration device certified by the German DKD, capable of issuing calibration certificates traceable to PTB and NIST.
