Method and apparatus for acoustic emission monitoring |
摘要 |
In order to locate a source of acoustic emissions, two multi-element transducers are employed. The elements of each transducer are subjected to an impinging acoustic wave at different moment in time depending upon the angle of the wave. Outputs from the elements of each transducer are compared with a look-up table to determine the angle. Then, another look-up table is used to determine the X-Y intersection of impinging wave angles from both transducers which locates the source.
