Abstract
An AE detector has an AE sensor and a destruction judging section. The destruction judging section judges it as a warning of destruction of a bearing when there are a predetermined number or more of points defined by parameters calculated based on signals from the AE sensor in a predetermined region of a parameter space defined by a plurality of parameters which can be created based on the signals from the AE sensor.
Claims5
An acoustic emission detector comprising:
- an acoustic emission sensor to detect an acoustic emission;
- and
- a destruction judging section that judges it as a
- warning of destruction of a material subject to destruction detection when a predetermined number or more of points defined by at least two parameters calculated based on a signal from the acoustic emission sensor are located within a predetermined region of a parameter space in the parameter space defined by at least two parameters that can be generated based on the signal from the acoustic emission sensor.
