Primary Calibration of Acoustic Emission Sensors by the Method of Reciprocity-Industrial Exploitation of the Calibration bench

摘要

This article follows one published in the last Congress EWGAE 2012 (1). After a few reminders theoretical developments made, including the integration of the opening of a sensor function, we present in this paper the results of validation on a large number of sensors used in acoustic emission. We take the opportunity to also introduce our automated calibration bench capable of measuring the sensitivity of the sensors using different kinds of excitation mode surface, longitudinal and transverse. This bench is used for both the manufacturing control and periodic inspection of the sensors in our studies and daily benefits.
