Air-bearing long stroke vibration exciter APS 129
Air-bearing ELECTRO-SEIS® Long Stroke Vibration Exciter with mounting table for high payloads up to 23 kg. Especially developed for the calibration and testing of big and heavy low frequency sensors as well as for sensor characterization (e.g. geophones or heavy seismic sensors).
Specifications
The APS 129 ELECTRO-SEIS® air bearing shaker is a long stroke, electrodynamic force generator specifically designed to be used for calibration and evaluation of accelerometers and other motion transducers. It provides excellent properties for low frequency excitation of such devices. The shaker consists of an air bearing drive attached to an air bearing mounting table that allows high payloads up to 23 kg (50 lbs) e.g. for the calibration of geophones and heavy seismic sensors.

Applications:
- calibration and test for seismic instruments
like geophones and heavy seismic sensors - seismic simulation for components
Rang of use:
- geological services, science, physics and
seismic applications - calibration and evaluation of accelerometers
and other motion transducers
Features:
- 133 N (30 lbf) or 186 N (42 lbf) force (sine
peak) - 254 mm x 254 mm (10 in x 10 in) air
bearing table - excellent waveform purity
- air bearing guidance and support system
carries DUTs up to 23 kg (50 lbs) with
very low transverse motion - efficient electrodynamic drive produces
sine, random or transient waveforms
