Air Bearing ShakerPrecision Air Bearing Calibration Exciter SystemModel K394A30 & K394A31
The Model K394A30/A31 Calibration Shaker System Air Bearing Shaker represents a new level of performance in calibration grade shakers. The K394A30/A31 continues the award winning PCB Group tradition of providing superior performance characteristics and ease of use while offering exceptional value and simplicity. A graphite air bearing combined with an ultra-stiff lightweight armature essentially eliminates transverse motion that plagues traditional flexure based shaker armature suspension systems.
The K394A30 utilizes an aluminum and beryllium core to achieve a frequency range of 2 Hz to 15 kHz. The K394A31 utilizes a beryllium only core to achieve a frequency range of 2 Hz to 20 kHz.
Unlike other air bearing shakers that use rubber bands to adjust the armature, the K394A30/A31 uses a unique Lorentz force lifting mechanism making calibration of various accelerometer sizes quick and easy. An integral reference accelerometer mounted within a beryllium core has a mounted resonance greater than 70 kHz permitting the shaker to be used for resonance searches to over 50 kHz while effectively eliminating the need for complicated mass loading corrections.
The K394A30/A31 was specifically designed for use in the demanding environment of production comparison accelerometer calibration systems such as The Modal Shop's Model 9155 Accelerometer Calibration Workstation.
