Patent number: 10935538Abstract: A method for assessing the condition of an oil using a portable computer coupled to a camera comprises: separating wear particles from a sample of the oil; capturing an image of the separated wear particles using the camera; and analysing the image and generating information about the condition of the oil using the portable computer. The method may be used for tracking the condition of an oil in a machine over a period of time. The methods are particularly useful for assessing the condition of an industrial oil e.g. a lubricating oil that has been used to lubricate moving parts in a machine.Type: GrantFiled: May 16, 2017Date of Patent: March 2, 2021Assignee: Castrol LimitedInventors: Sander Gaemers, Bryan Rabenau, Marcel Jerusalem
