    Abstract:

    A new oil sensor system is presented for the continuous, online measurement of the wear in industrial gears, turbines, generators, transformers and hydraulic systems. Detection of change is much earlier than existing technologies such as particle counting, vibration measurement or recording temperature. Thus targeted, corrective procedures and/or maintenance can be carried out before actual damage occurs. Efficient machine utilization, accurately timed preventive maintenance, a reduction of downtime and an increased service life and can all be achieved.<br />The oil sensor system measures the components of the complex impedances X of the oils, in particular the electrical conductivity, kappa and relative dielectric constant, epsilon r, and the oil temperature T. The values kappa and epsilon r are determined independently.<br />Inorganic compounds occur at contact surfaces from the wear of parts, broken oil molecules, acids or oil soaps. These all lead to an increase in the electrical conductivity, which correlates directly with the wear. In oils containing additives, changes in dielectric constant infer the chemical breakdown of additives. A reduction in the lubricating ability of the oils, the determination of impurities, the continuous evaluation of the wear of bearings and gears and the oil aging all together follow the holistic approach of real-time monitoring of changes in the oil-machine system.<br />Different application examples from the industrial sectors wind energy and gearbox test stands and will be presented.
