Oil micro water sensor

1、Oil micro water sensor Product Introduction

Oil micro water sensor can detect lubricating oil contamination in a timely manner and monitor oil micro-water, free water, and dielectric constant 24 hours a day without interruption.Oil micro water sensor is used for real-time, online monitoring of lubricating oil moisture contamination levels. Continuous monitoring of the oil's condition improves condition-based maintenance efficiency, optimizes oil change intervals, and reduces reliance on offline analysis.

Oil micro water sensor integrates micro-water monitoring technology to detect trace amounts of moisture and water activity in the oil, while also monitoring dissolved and free water to determine the oil's health status. Based on our years of experience in online oil monitoring, it analyzes the oil health index, assesses lubricating oil additive wear, monitors oil aging, and determines oil contamination levels.

Oil micro water sensor helps users improve equipment asset health management, using real-time monitoring results to assist in maintenance decisions and prevent abnormal wear and corrosion caused by oil moisture contamination.

2、Oil micro water sensor Features

Wide range of applications, suitable for all lubricating oils

Simultaneous measurement of multiple parameters allows for timely detection of water contamination in lubricating oil, helping users to filter ingress water and prevent equipment malfunctions caused by water contamination.

No customer calibration required for free water; the sensor has an automatic calibration function.

Big data oil analysis algorithms help customers solve diagnostic problems and include 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 monitoring under high-speed flow conditions, suitable for oils of different viscosities, robust and durable.

Compact structure, easy to install.

3、Oil micro water sensor Application areas

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

Oil micro water sensor can continuously monitor the moisture contamination level of the oil in the oil circuit 24 hours a day, reflecting the oil's operating status in real time. This helps users avoid or mitigate equipment failures caused by lubricating oil ineffectiveness.

Oil micro water 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.
