Abstract
Magnetic chip detectors and associated for detecting metallic chips in engine fluid of an engine are provided. A magnetic chip detector includes first and second magnetic chip capture zones. The first magnetic chip capture zone includes a first electrically conductive terminal spaced apart from a second electrically conductive terminal to define a first chip-receiving gap therebetween. The second magnetic chip capture zone includes a third electrically conductive terminal and either the second electrically conductive terminal or a fourth electrically conductive terminal to define a second chip-receiving gap therebetween. The magnetic chip detector includes an electric circuit including both the first chip-receiving gap and the second chip-receiving gap. The electric circuit provides an output indicative of a chip detection by one or both of the first magnetic chip capture zone and the second magnetic capture zone.
