Abstract
A sensor for detecting erosion of a wear surface of a component, particularly a liner attached to the mill shell of a rotating grinding mill. The sensor comprises a conductive element embedded in the component, the conductive element comprising a first end positioned at a first distance from the wear surface, at least one conductive loop comprising a wear portion positioned at a second distance from the wear surface proximate to the first end and a circuit coupled to the at least one element for determining a continuity of the conductive loop.
Claims14
A sensor for detecting erosion of a wear surface of a component, the sensor comprising:
- at least one conductive trace on a substrate, said substrate attached to the component such that a wearing portion of said trace between a first trace end and a second trace end comes within a predetermined distance from the wear surface;
- and
- a circuit for sensing when said first end is isolated from said second end;
- wherein the component is manufactured from a material selected from the group consisting of rubber, cast iron, steel and ceramics or combinations thereof.
