  • Patent number: 8330610
    Abstract: A system, method, and apparatus for detecting wear in a screening arrangement is disclosed. The system, method, and apparatus can include a sensor that is configured to provide a notification signal when a surface of a screen panel has worn to a threshold level. The threshold level can be based at least in part on the amount of wear that requires replacement of a screen panel to prevent breakthrough or contamination. The notification signal provided by the sensor can be used to identify which screen panel or region of screen panels has been worn to the threshold level so that the screen panels can be replaced in a timely manner. The sensor may be coupled to a conductor embedded in one of the screen panels that is altered when a screen panel has worn to a threshold level, triggering the sensor to provide the notification signal.
