Abstract

A system and method to detect non-ferrous debris from a non-ferrous roller bearing element. The system includes a trap in fluid communication with a lubrication fluid of the non-ferrous bearing and a sensor operably associate with the trap. The method includes trapping the non-ferrous material debris in the lubrication fluid with the trap and triggering the sensor upon detection of the non-ferrous material debris trapped within the trap.
