Abstract

The calibration of acoustic emission sensors is vital for industrial users to maintain a calibrated measurement system and to demonstrate measurement traceability. Currently, no independent calibration service for acoustic emission sensors is available within Europe. The National Physical Laboratory is undertaking work to develop a measurement facility which will enable traceable calibration of acoustic emission (AE) sensors in terms of their response to out-of-plane and in-plane displacements.
This report documents the results of a feasibility study into possible methods for the calibration of an AE sensor for it response to an in-plane surface displacement. The study has demonstrated the feasibility of the a method by successfully measuring the transverse acoustical particle displacement of a propagating shear wave and also analyses the future requirement to implement such a method as a calibration method.
