PRIMARY CALIBRATION OF GEOPHYSICAL AND SEISMIC VELOCITY SENSORS

• Abstract:

  This paper describes first measurement results determined with a new primary calibration system according to ISO 16063-11 that can handle very heavy devices under test (DUT) with a weight up to 50 kg allowing a precise vertical excitation of the DUT. This required the development of a new vibration exciter that can compensate the high payload and covers the broad frequency range from 0.05 Hz to 400 Hz without exceeding the cross motion and THD limits defined in the ISO standard.
