Operation and accuracy of particle counters for on-line condition monitoring of hydraulic oilsTič, Vito (Avtor) Lovrec, Darko (Avtor) Edler, Jörg (Avtor) hidravlična oljaon-line monitoringštevec delcevReal-time monitoring of oil contamination in hydraulic system is one of the most effective measures of prevention and early diagnosis for system failures. Contaminants such as particles, moisture, soot, fuel, and process fluids are commonly found in industrial lubricants and hydraulic fluids. However, particle contamination is typically recognized as the most destructive to the oil and machine. Paper presents operation principle of today's on-line particle counters and reports about their accuracy levels. Report is based on experimental research where 4 different cost-effective on-line particle counters were compared to a sophisticated laboratory-based particle counter.20122015-07-10 12:36:34Delo ni kategorizirano50170UDK: 621.22:621.89COBISS_ID: 16358422ISSN pri članku: 1584-2665NUK URN: URN:SI:UM:DK:O3K2FFA9sl
