Abstract: Mining machine is one of the main equipment of fully mechanized mining equipment, hydraulic oil is widely used in all kinds of machinery, the moisture content of hydraulic oil is a very important index. This paper proposes a real-time detection system for hydraulic oil products, based on the ex-isting detection method of hydraulic oil products, including data acquisition, sensor design, model building, hardware circuit design and software programming. The system adopts capacitive sensor module, main control module, display module, temperature sensing module for integrated design, which can realize multi-function measurement. Capacitance value will change under different water content, and the change of capacitance value can reflect the water content in oil products. After the test experiment, the accuracy of the detection system can reach 0.01%, and can realize real-time online detection, environment-friendly and wide detection range, with practical use significance. Its application can make the moisture content data of oil products displayed in real time, to ensure that abnormal situations can be found in time to alarm, to ensure the reliability of the hydraulic system, prolong the service life of hydraulic components to provide a new guarantee.
