Multi-parameter oil sensor

1、Multi-parameter oil sensor Product Introduction

Multi-parameter oil sensor is used for real-time, online monitoring of lubricating oil health and wear. Continuous monitoring of the oil condition improves condition-based maintenance efficiency, optimizes oil change intervals, and reduces reliance on offline analysis.

Multi-parameter oil sensor integrates electrochemical impedance spectroscopy (EIS) to detect oil impedance spectra, ultrasonic viscosity monitoring to detect oil viscosity and density, inductive magnetic field analysis to assess equipment wear, and micro-water monitoring to detect trace amounts of moisture and water activity in the oil. It can also monitor dissolved and free water, thus obtaining the oil's health status. Based on our years of experience in online oil monitoring, it analyzes the oil health index. It assesses the wear of lubricating oil additives, monitors oil aging, and determines oil contamination levels.

Multi-parameter oil sensor helps users improve equipment asset health management, assisting in maintenance decisions based on real-time monitoring results and preventing abnormal wear and corrosion caused by oil aging and contamination.

2、Multi-parameter oil sensor Features

Wide range of applications, suitable for all lubricating oils

Simultaneous measurement of multiple parameters allows for timely detection of lubricating oil contamination and aging, helping users optimize oil change intervals.

Adsorption-based wear particle concentration monitoring enables timely assessment of equipment wear conditions.

No customer-required free water calibration; the sensor features automatic calibration.

Analyzes oil contamination sources for more targeted oil fault analysis.

Big data oil analysis algorithms help customers solve diagnostic challenges; includes built-in health index analysis.

24/7 uninterrupted monitoring provides timely feedback on oil status.

Strong compatibility, compatible with CAN-J1939 and RS485-Modbus RTU.

Suitable for oil monitoring under high-speed flow conditions, eliminating the need for static oil monitoring; exhibits stronger viscosity interference resistance than similar sensors; robust and durable.

Integrated structural design facilitates installation.

3、Multi-parameter oil sensor Application areas

Lubricating oil is the "blood" of critical equipment. Lubricating oil failure directly leads to abnormal wear of mechanical structures and critical functional components, a major cause of large equipment failures and serious accidents.

Multi-parameter oil sensor can continuously monitor the aging and contamination levels of the oil in the hydraulic system 24 hours a day, providing real-time feedback on the oil's operating status. This helps users avoid or mitigate equipment failures caused by lubricating oil failure.

Multi-parameter oil sensor can be widely used in industries such as power, mining, cement, shipbuilding, military, industrial manufacturing, papermaking, petrochemicals, transportation, metallurgy, aviation, oil fields, and ports, for applications such as wind turbine gearboxes, aircraft/helicopter gearboxes, hydraulic transmission systems, machining centers, steam turbines, gearboxes, and gasoline/diesel engines.
