Device for detecting a wear level of a wear plate

A first conductor is embedded in the first dielectric layer to a first wear depth, where the first wear depth is associated with a first threshold wear level. A second dielectric layer overlies the first dielectric layer to a second wear depth. The second wear depth is associated with a second thres...

Beschreibung
Zusammenfassung:	A first conductor is embedded in the first dielectric layer to a first wear depth, where the first wear depth is associated with a first threshold wear level. A second dielectric layer overlies the first dielectric layer to a second wear depth. The second wear depth is associated with a second threshold wear level greater than the first threshold wear level. A second conductor is embedded in the second dielectric layer and separate from the first conductor. An indicator is adapted to indicate whether the wear plate is the first threshold wear level or the second threshold wear level.
