Abstract
A debris sensor may include a body including a first end and a second end, a ferrous particle sensor connected to the body, and a magnetic chip collector connected to the body at a position closer to the second end than the ferrous particle sensor. A plurality of magnets may be disposed closer to the second end than the magnetic chip collector. A non-ferrous particle sensor may be connected to the body and the non-ferrous particle sensor may be disposed closer to the second end than the plurality of magnets.
Claims22
A debris sensor, comprising:
- a body including a first end and a second end;
- a ferrous particle sensor connected to the body;
- a magnetic chip collector connected to the body at a position closer to the second end than the ferrous particle sensor;
- a plurality of magnets disposed closer to the second end than the magnetic chip collector;
- and
- a non-ferrous particle sensor connected to the body;
- wherein the magnetic chip collector is configured to generate a magnetic field and to attract ferrous particles, and the ferrous particle sensor is configured to sense changes in the magnetic field generated by the magnetic chip collector caused by the ferrous particles.

A debris sensor, comprising:
- a first sensor;
- a source of a first magnetic field disposed downstream of the first sensor, the first magnetic field configured to be sensed by the first sensor;
- a second sensor disposed downstream of the source of the first magnetic field;
- and
- a source of a second magnetic field disposed upstream of the second sensor, the second magnetic field configured to be sensed by the second sensor;
- wherein the first sensor is configured to sense particles of a first type when the particles of a first type cause changes in the first magnetic field, the second sensor is configured to sense particles of a second type, and the debris sensor is configured to provide fluid communication from its inlet to its outlet.
