P2.5 - High-Precision Online Sensor Condition Monitoring of Industrial Oils in Service for the Early Detection of Contami¬nation and Chemical Aging

M. R. Mauntz, U. Kuipers & J. W. Gegner
A new online diagnostics system for the continuous condition monitoring of, e.g., lubricating and insulating oils in industrial gearboxes or transformators is presented. Characteristic features of emerging component damage, such as wear or chemical aging, are identified in an early stage. The OilQSens® Sensor effectively controls the proper operation conditions of bearings or gears. The online diagnostics system measures components of the specific complex impedance of oils. For instance, metal abrasion due to wear debris,...
