Mk6 12ch

Graviner Mk6 12ch is listed in this library as a marine oil-mist detection equipment in the Oil Mist Detection / Oil Mist Detector category. Equipment of this class is typically installed on or adjacent to the engine crankcase with sampling points or sensors connected to the monitored crankcase compartments. Its shipboard purpose is to detect abnormal oil-mist conditions that can indicate overheating and an increased risk of crankcase fire or explosion. The exact piping, electrical, control, foundation, and accessory arrangement depends on the vessel and the supplied configuration. No additional verified rating, capacity, weight, dimension, or operating limit is provided in the source entry. Where adjacent models in the same product family differ in rating, size, materials, control options, certification, or accessories, refer to the manufacturer documentation for the exact model-specific differences.

Common failures & inspection points

Contaminated optics, sample paths, or sensor chambers from oil deposits cause drifting readings, false alarms, or failed self-tests
Blocked sampling pipe or ejector flow prevents representative crankcase atmosphere reaching the detector and can cause low or missing readings
Fan, pump, ejector, or flow-monitor faults reduce sample flow and trigger flow alarms
Electrical supply, processor, or communication failure can disable one or more channels or the complete monitor
Incorrect zeroing, calibration, or sensor replacement can cause inconsistent channel readings or nuisance alarms

Service & Maintenance

Inspect sampling pipes, drains, optics or sensing chambers, fans or ejectors, channel identification, alarm and shutdown interfaces, power supply, and self-test results. Cleaning, zeroing, and functional testing must follow the engine and detector manufacturer procedures.
