According to absolute vibration calibration of laser interferometry in ISO 16063-11—1999

the standard accelerometer with amplifier was calibrated by the modified Mach-Zehnder Sine-approximation method based vibration standard device.Under the reference condition and within the complete frequency range

the measurement uncertainty of standard accelerometer with amplifier of amplitude and phase sensitivity calibration was evaluated.The introduction of phase measurement of turbine shafting status monitoring and diagnosis is very effective.The application results show the this evaluation method has great guidance effect on vibration quantity verification and calibration of measurement uncertainty evaluation.
