Product Overview

The JCQM-2400 Grease Quality Sensor is designed for real-time, online monitoring of grease health. By continuously monitoring grease condition, it enhances condition-based maintenance efficiency, optimizes grease change intervals, and reduces reliance on offline analysis.

Metal particles generated during the operation of bearings, gears, and other components in transmission machinery enter the grease. By installing the JCQM-2400 grease sensor in the lubricant, it monitors the concentration, properties, and accumulation trends of metal particles within the grease. It records monitoring data in real time and, through data analysis, determines the health status of the transmission equipment. This provides reliable early warnings and service life estimates for mechanical equipment.

The JCQM-2400 utilizes electrochemical impedance spectroscopy (EIS) technology to assess lubricant quality factors, thereby determining the lubricant’s health status. Impedance spectroscopy can measure multiple parameters, enabling the evaluation of additive depletion, monitoring of lubricant aging, and identification of contamination.

The JCQM-2400 helps users improve the health management of their equipment assets. Based on real-time monitoring results, it assists in maintenance decisions, preventing abnormal wear and corrosion caused by grease aging and contamination.

Application Areas

Grease failure directly leads to abnormal wear of mechanical structures and critical functional components, serving as the primary cause of major equipment failures and serious accidents. The JCQM-2400 provides 24/7 uninterrupted monitoring of grease aging and contamination levels, providing real-time feedback on grease condition. It helps users prevent or mitigate equipment failures caused by grease failure.

The JCQM-2400 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.
