Oil Mist Detector · Oil Mist Detection
Graviner Mark 5 4ch is a oil-mist detector. It is installed on or near a large diesel engine with sampling connections from crankcase compartments to a detector or scanner unit. Its purpose is to detect an abnormal increase in crankcase oil mist that may precede a hot-bearing event or crankcase explosion hazard. The exact sampling method, optical sensing arrangement, alarm logic and engine-shutdown interface depend on the installed detector model. The exact model designation identifies sampling capacity, detector architecture and engine interfaces; these details must be confirmed from manufacturer and engine documentation.
What our service work and the manufacturer documentation say about keeping this model running.
Inspect and clean sampling lines, detector chambers, filters and optical components according to the approved procedure. Verify sample-flow indications for all engine compartments and investigate recurring channel faults. Function-test alarms and any engine interface without bypassing protective functions beyond the authorized test method. Check power supplies, drains and heater or fan arrangements where fitted. Record cleaning, calibration and sensor replacement work because trend changes can indicate developing contamination. Refer to manufacturer and engine documentation for exact alarm settings, calibration methods and test intervals.
Keep filters, seals, sampling-line fittings, lamps or optical components where applicable, fan or pump service parts and manufacturer-recommended electronic modules. Use only components compatible with the approved engine protection system. Maintain cleaning tools and consumables specified by the manufacturer.
