November 25, 2005, Cincinnati, OH – THE MODAL SHOP, INC., a PCB Group Co., introduces shock sensor calibration capabilities to the workhorse Model 9155C Accelerometer Calibration Workstation.

The Model 9155C-525 Shock Calibration option provides verification and linearity check from 100g to 10,000g allowing accurate calibration of shock accelerometers at amplitude levels used in actual testing.  The system uses a state-of-the-art pneumatically actuated exciter to provide controlled and consistent impacts.  It also includes a variety of impact anvils and projectiles to tailor the impulse shape for frequency content and shock level to cover the entire 100g to 10,000g amplitude range.

The shock accelerometer calibration capability seamlessly integrates into The Modal Shop’s Model 9155C Accelerometer Calibration Workstation that performs calibrations on both ICP® (IEPE) and charge mode accelerometers, providing both sensitivity and phase data.  Calibrations are performed using the 'back-to-back' method according to ISO 16063-21.  All sensor information and calibration data is managed within a Microsoft Access database that allows for customizable calibration reports conforming to the requirements of ISO 17025 for calibration certificates.  The system also self-documents measurement uncertainty according to ISO 16063-21.
