Multi-parameter oil quality sensor

1、Multi-parameter oil quality sensor Product Introduction

Multi-parameter oil quality sensor monitors key lubrication characteristics, integrating the measurement of oil-in-water content, free water, dielectric constant, ferrous debris, pressure, and fluid level.Multi-parameter oil quality 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 quality 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 quality 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 quality sensor Features

Integrated structural design for easy installation.

3、Multi-parameter oil quality 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 quality 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 quality 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.
