Performance
The APS 42 ELECTROSEIS® vibration exciter is used to determine the dynamic characteristics of mechanical structures, typically by exciting them at resonance. Under these conditions, the shaker mainly supplies the mechanical power dissipated by damping, while performance is limited by its maximum force and velocity and depends on the mechanical impedance at the drive point. The following diagrams therefore show the achievable force, velocity, and acceleration envelopes versus resonance frequency and payload.

PA 800 DM
For all vibration exciters that require a 810 VA power amplifier (load impedance 2.5 Ω). The PA 800 DM offers a max. frequency range DC ... 25 kHz, small harmonic distortion, excellent stability even with temperature or supply line variations and helpful protection functions.
APS 0109
The APS 0109 automatically controls the zero position of a vibration exciter irrespective of its load. It is essential to employ a position controller of type APS 0109 especially when working with an air-bearing vibration shaker without any integrated automatic load-compensation.
APS Auxiliary Table Kits
Enhance your shaker system’s versatility with auxiliary mounting tables that provide a stable platform for both horizontal and vertical setups.
Designed to accommodate components, model structures, accelerometers and other low-frequency sensors, they enable precise, dependable vibration testing across a wide range of applications.
APS Handles & Bars
Handles suitable for vibration exciter APS 113, APS 400 and APS 420 vibration exciters.

APS 113
Ball-bearing ELECTRO-SEIS® Long-Stroke vibration exciter specifically designed to be used alone or in arrays for modal excitation of complex structures, particularly when low frequencies are required. Different operating modes with reaction masses, fixing points or auxiliary table kits multiply the application possibilities.
APS 400
ELECTRO-SEIS® Long-Stroke vibration exciter with 445 N max. force that is suitable for excitation of large structures such as ceilings or bridges.
APS 4001
The APS 4001 - Horizontal Reaction Mass System provides a means of extending the rated force output for the APS 400 exciter to frequencies as low as 0.5 Hz.
This reaction mass allows the shaker armature to be connected through the base plate to the structure under test.
