Improvement of the Primary Low-Frequency Accelerometer Calibration System at INMETRO

G. P. Ripper, C. D. Ferreira, R. S. Dias, G. B. Micheli
  • Abstract:
    This paper presents the results of recent improvements of the primary low-frequency accelerometer calibration system at INMETRO. The interferometric system was upgraded, a new software developed and the sine- approximation method was implemented. This new system allows the calibration of the complex sensitivity of accelerometers from 0,2 Hz to 100 Hz with reduced uncertainty.
