Abstract
Real-time monitoring of oil contamination in hydraulic system is one of the most effective measures of prevention and early diagnosis for system failures. A compact on-line particle counter sensor based on light-blockage principle for monitoring hydraulic oil is presented in the article. A novel method is used in this sensor, which can calculate the particle number concentration without a metering pump. The experimental results show that the particle counter sensor can measure the concentration as well as the approximate size of the hydraulic oil particles with a high precision.
