Continuing the award-winning PCB Piezotronics tradition of providing superior performance characteristics, Air Bearing Accelerometer Calibration Shakers offer ease-of-use coupled with exceptional value and simplicity. A graphite air bearing combined with an ultra-stiff light-weight armature essentially eliminates transverse motion that plagues traditional flexure-based shaker armature suspension systems.

Highlights

  • Provides accurate calibrations conforming to ISO 16063 Part 21
  • Wide frequency range of 5 Hz to 20 kHz
  • Drastically reduces uncertainty by virtually eliminating transverse motion
  • High throughput with simple mounting and setup
  • Proven design used in over 100 000 calibrations annually at PCB Piezotronics
  • Calibrate at low frequencies using full 10 mm stroke length
  • Easily adjusts to calibrate a wide range of sensor sizes

Unlike other air bearing shakers that use rubber bands to adjust and balance the armature, Air Bearing Accelerometer Calibration Shakers from The Modal Shop use a unique Lorentz force lifting mechanism making calibration of various accelerometer sizes quick and easy. An integral reference accelerometer mounted within a light-weight insert 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. In addition, this innovative two-part armature design provides electrical isolation of the sensors, improving accuracy by eliminating electrical noise in the calibration measurement. The included SmartAmp™ power amplifier is uniquely designed for calibration shaker use by controlling the DC current to position the armature and protecting the shaker by automatically shutting down when there is no air flow to the shaker.
