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. Some models have a horizontal air bearing table coupled to the driver unit that allows high payloads up to 23 kg e.g. for the calibration of geophones.
APS 129 Vibration Exciter
133 N (30 lbf) Long Stroke Shaker with air bearings and payload table
The APS 129 ELECTRO-SEIS® Long Stroke Shaker is a 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. This model has a horizontal air bearing table coupled to the driver unit that allows high payloads up to 23 kg e.g. for the calibration of geophones and heavy seismic sensors.
