System, method, and apparatus for detecting wear in a screening arrangement
First Claim
1. A system for detecting wear in a screening arrangement having a plurality of screen panels, comprising:
- a monitoring device; and
a sensor, the sensor being positioned in the screening arrangement;
wherein said sensor is configured to provide a notification signal to said monitoring device when a top surface of at least one of the plurality of screen panels has worn to a threshold level, the threshold level associated with a depth of wear of the screen panel.

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.

25. A screen panel for use in a system for detecting wear in a screening arrangement, the screen panel comprising:
-
a peripheral edge portion and a top surface formed at least partially from a resilient material; a conductor embedded in said resilient material, said conductor being positioned in said resilient material so that said conductor is altered when the top surface of said screen panel has worn to a threshold level, the threshold level associated with an amount of wear of the screen panel that affects aperture size of the screen panel; wherein said conductor is configured to be coupled to a sensor that provides a notification signal when said conductor is altered in the screen panel. - View Dependent Claims (26, 27, 28, 29, 30)
