Abstract: An oil filter for an oil filtration system. The filter is configured for insertion into an oil filtration unit. The filter comprises a central opening extending along a central axis of the filter, at least one second physical structure having a second cross sectional shape and a predefined longitudinal length in relation to the central axis of the filter, and an inner periphery of the second physical structure being arranged to mate with the outer periphery of the first physical structure allowing the filter to reach its correct insertion position in the oil filtration unit by the second physical structure at least partly surrounding the first physical structure. The end surface of the filter relative to the central axis of the filter comprises the second physical structure, and the second physical structure comprises a material configured to serve as a filtering material of the filter.

Abstract: The present invention relates to a sensing unit for monitoring the condition of a liquid, the sensing unit comprising at least one sensor and an evaluation unit. The sensing unit is adapted to measure two or more parameters of the liquid by use of at least one sensor, where the parameters relate to at least liquid degradation or wear debris particle generation. The at least one sensor is adapted to provide at least two signals, each signal providing its values in a fashion suitable for developing a mean value and a variance different from zero over a course of at least two measurements. The evaluation unit is adapted to correlate the measured signals, and to evaluate the condition of the liquid by comparing the measured at least two parameters. Thereby, a reliable monitoring system giving continual feed-back on the performance of the lubricant and the machine in an auto-correlated manner is obtained, thus allowing continual adjustments to improve uptime and machine life.

Abstract: An assembly, as disclosed herein, is usable or operable to facilitate the separation and removal of water from an oil of an oil supply. The assembly, in an embodiment, includes a housing defining an inner space. The housing enables a flow from an oil supply to an oil inlet of the housing. The assembly also includes an inlet pump that enables flow from the oil supply to the oil inlet. The housing's inner space is configured so that the oil and foam formed on the oil's surface and are released to an oil outlet of the housing. The housing is configured to output gas from the inner space of the housing, thereby removing water from oil.
