Linearity Check Now Available for Accelerometer Calibration Workstation

January 25, 2006, Cincinnati, OH – THE MODAL SHOP, INC., a PCB Group Co., introduces the addition of sensor linearity check capabilities to the workhorse Model 9155C Accelerometer Calibration Workstation.

The Model 9155C-501 Linearity option allows users to perform multipoint sensor linearity checks up to 40gpk using The Modal Shop’s calibration-grade air-bearing shaker.  Linearity checks can be performed up to an amplitude of 500gpk with a mechanical amplifier bar.  Verifying linearity provides additional assurance of sensor health and performance, increasing confidence in measurement accuracy.

The easy-to-use software GUI automates data acquisition across specified amplitude range and 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.
