Primary calibration of accelerometers in medium and high frequencies

Project Description

The specific task of this comparison is the measurement of the magnitude and phase of the complex voltage sensitivity of two accelerometer, one single-ended and one back-to-back, in medium and high frequency domain (10 to 20 000 Hz). This comparison will be linked to the key comparison CCAUV.V-K5 which is under progress in 2017. 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".
The pilot lab is not yet assigned.
