Product Overview
Metal particles generated during the operation of bearings, gears, and other components in transmission machinery can enter the return oil lines along with the lubricating oil. By installing an online lubricating oil metal particle monitoring sensor in the return oil line, the system monitors the size, mass, properties, and accumulation trends of metal particles in the return oil line. It records the monitoring data in real time and, through data analysis, determines the health status of the transmission equipment. This provides reliable early warning and service life estimation for mechanical equipment.
The lubricating oil metal particle online monitoring sensor primarily consists of a sensor, a signal conditioning module, and connecting cables. It integrates knowledge from multiple disciplines, including mechanics, electronics, signal processing, and computer science, making it a typical product of the convergence of various high-tech fields. The sensor is installed in the oil circuit of the lubrication system. By continuously monitoring the accumulation of lubricating oil metal particles—including their quantity and size—in the power transmission system, it analyzes the system’s health status, enabling proactive maintenance measures to ensure reliable system operation.
This sensor utilizes the principle of electromagnetic induction to detect the quantity of metal particles in the lubrication system, serving as a basis for determining the extent of damage to bearings or gearboxes. The sensor must be installed upstream of the filter, at the lowest point of the return oil line.
Application Areas
Lubricating oil is the “lifeblood” of major equipment. Lubricant failure directly leads to abnormal wear of mechanical structures and critical functional components, serving as the primary cause of large-scale equipment failures and catastrophic accidents. The JCME-5 provides 24/7 uninterrupted monitoring of wear levels in the oil circuit, providing real-time feedback on the oil’s condition. It helps users prevent or mitigate equipment failures caused by lubricant failure.
The JCME-5 is widely applicable across industries such as power generation, mining, cement, shipping, defense, industrial manufacturing, papermaking, petrochemicals, transportation, metallurgy, aviation, oil fields, and ports. Specific applications include wind turbine gearboxes, aircraft/helicopter gearboxes, hydraulic transmission systems, machining centers, steam turbines, gearboxes, and gasoline/diesel engines.
