Classification: CPC G | IPC G

Claim 8:
9. An electromagnetic chip detector for detecting a metallic chip in engine fluid of an engine, the electromagnetic chip detector comprising:
a first electrically conductive terminal;
a second electrically conductive terminal spaced apart from the first electrically conductive terminal to define a chip-receiving gap therebetween;
a first circuit magnetizing the first electrically conductive terminal to have a first polarity and magnetizing the second electrically conductive terminal to have a second polarity opposite the first polarity;
a second circuit detecting a presence of a chip electrically connecting the first electrically conductive terminal and the second electrically conductive terminal together; and
a power source supplying electric current to both the first circuit and the second circuit via a first node and a second node when the chip electrically connects the first electrically conductive terminal to the second electrically conductive terminal.
