Abstract
A bearing arrangement is provided having a bearing mounted in a housing, wherein a grease lubricant is present within the housing for lubricating the bearing. The arrangement further provides a support frame made of an electrically insulating material, arranged in a space within the housing between the bearing and a housing seal. The support frame is provided with at least one electrode pair having first and second electrodes arranged such that a portion of the grease lubricant is located between the first and second electrodes. A capacitance meter is provided for measuring a capacitance between the first and second electrodes. The first and second electrodes of the at least one electrode pair are provided on a radially oriented surface of the support frame, which surface is arranged such that the grease is able to move in an axial direction over the surface.
