Heart of the Calibration System

Air Bearing Vibration Calibration Shaker

Shaker Model K394B30 and K394B31
Included in System Option 9155D-830 and 9155D-831

Our Air Bearing Calibration shakers represent the de facto global standard in calibration-grade hardware while continuing the award-winning PCB Group tradition of providing superior performance characteristics and ease of use alongside exceptional value and simplicity.

  • Wide frequency range of 2 Hz to 50 kHz (calibration from 5 Hz to 20 kHz)
  • Drastically reduces uncertainty by virtually eliminating transverse motion
  • Integral quartz ICP ® reference ensures low noise operation with long-term stability
  • Lorentz force coil enables rapid centering of sensors with varying mass
  • High stiffness beryllium insert yields high frequency calibration

BENEFITS

  • Reduces uncertainty
  • Allows high throughput with simple mounting and setup
  • Rugged, reliable design proven on PCB Piezotronics production lines
  • Exceeds ISO 16063-21 requirements

The Accelerometer Calibration Workstation Model 9155 allows accurate back-to-back comparison calibration of ICP® (IEPE), charge, piezoresistive, capacitive and voltage mode accelerometers in accordance with ISO 16063-21 (2003). Every system is delivered with its reference calibrated directly by The Modal Shop’s ISO 16063-11 compliant, A2LA accredited Laser Primary system, assuring world-class uncertainties.
