ELECTRICAL IMPEDANCE BASED CALIBRATION OF ACCELEROMETERS

Andreas Havreland

Abstract

This contribution proposes a methodology to predict the transfer function of an accelerometer solely based on an electrical impedance measurement. Such impedance measurement can be conducted in-situ and has certain advantages for some types of accelerometers and under certain measuring conditions. A proof-of-concept study has been conducted where the methodology is used to estimate the sensitivity at 160 Hz, the proposed method underestimates the sensitivity by 9% compared to a conventional vibration experiment.
