The support frame includes at least one electrode pair having first and second electrodes arranged to enable grease lubricant to contact therewith. A capacitance meter provided for measuring a capacitance between the first and second electrodes. The support frame provides a radially oriented surface and a plurality of ribs that extend in a radially inward direction, the ribs having sufficient circumferential spacing to enable grease to flow between adjacent ribs. One of the first and second electrodes is provided on the radially oriented surface of the support frame or on a rib surface that faces an adjacent rib."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Capacitance measurement in a bearing housing","description":"A bearing arrangement having a bearing mounted in a housing, wherein a grease lubricant is present within the housing for lubricating the bearing, a support frame at least partly made of an electrical","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9644684","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
