Air Bearing Exciter

Vibration Exciter for Calibration and Testing Purposes

The APS Dynamics series of air bearing long stroke vibration exciters provide excellent properties for low frequency excitation of accelerometers and other low frequency instruments and sensors.

 

These are DC response electrodynamic shakers that operate at frequencies up to 200 Hz with a peak-to-peak stroke of 150 mm (6 inches). Acceleration amplitudes as high as 60 m/s2 (6 g) can be achieved.

 

Some models have a horizontal air bearing table coupled to the driver unit that allows high payloads up to 23 kg for the calibration of geophones and other devices. The shakers can also operate in the horizontal or vertical orientation.

APS Calibration Systems

Our APS systems are flexible in structure and so can easily be adapted to the customer‘s requirements. For instance, one system may include several vibration exciter for the purpose of covering a wider frequency range.

 

They can be integrated into a SPEKTRA CS18 System as well. A typical use case is the CS18 VLF Calibrations System for geophones and seismic sensors.
