Development of Online Measuring Instrument for Water-in-Oil percentage Based on MCU

摘要

Water may access to hydraulic and lubricant system due to various reasons, so the lubricant oil in hydraulic system will be out of work for high water-in-oil percentage. Traditional measuring instruments for water-in-oil percentage have slower response-time and higher costs. The principle of water-in-oil percentage detection, capacitance to voltage signal conversion and the structure of measurement system are proposed in this paper. It is demonstrated that the detection device which uses the mixed technology of real-time MCU, XE2004 conversion chip and smart sensor can quickly and precisely measure water-in-oil percentage and avoid the potential hazards.
