Oil Mist Detector · Oil Mist Detection
GE Marine GE OMD-7 4ch is a crankcase oil-mist detector (Oil Mist Detection / Oil Mist Detector). It is normally installed on or close to a diesel engine with sampling connections from the crankcase spaces. It is intended to detect an abnormal oil-mist condition that can precede a crankcase fire or explosion. The meaning of any embedded size or rating code should be confirmed in manufacturer documentation. In service it interfaces with crankcase sampling pipes or sensors, the detector unit, engine alarm and shutdown logic and any cleaning-air arrangement.
