Service characteristics of acoustic emission transducers
Abstract
A procedure for the calibration of piezoelectric acoustic emission transducers is described. The reliability of the determined frequency characteristics is estimated, and methods are described by which an acoustic signal can be reproduced over a wide frequency range. Calibration results are presented for different types of transducers.
