GE OMD-7 8ch
GE Marine GE OMD-7 8ch is a crankcase oil-mist detector in the supplied category '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. Compared with neighbouring entries in the same series, the supplied list identifies this unit by its model designation; 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. Model-specific limits, settings, dimensions and acceptance criteria that are not stated in the supplied data should be taken from the manufacturer documentation.
