Magnetic chip detector

Magnetic chip detector

A magnetic chip detector is an electronic instrument that attracts ferromagnetic particles (mostly iron chips). It is mainly used in aircraft engine oil chip detection system. Chip detectors can provide early warning of an impending engine failure and thus greatly reduce the cost of engine overhaul.

Operation

Chip Detectors consist of small plugs which can be installed in engine oil filter or oil sump. Over a period of time engine wear and tear causes small metal chips to break loose from engine parts and circulate in engine oil. When metal chips bridge the gap in the plugs, a warning light on the instrument panel illuminates indicating presence of metal chips.
