Primary calibration of accelerometers at low frequencies

Project Description

The specific task of this comparison is the measurement of the magnitude and phase of the complex voltage sensitivity of one servo accelerometer in low frequency domain (0.1 to 200 Hz) as no comparison has ever been performed in this domain. The voltage sensitivity shall be calculated as the ratio of the amplitude of the output of the accelerometer to the amplitude of the acceleration at its reference surface with primary means in accordance with ISO 16063-11 : 1999 “Methods for the calibration of vibration and shock transducers - Part 11: Primary vibration calibration by laser interferometry”.

Final Report 2015-08-18

The comparison has been completed and results are published in the KCDB.
