Water in Oil Sensor

1、Water in Oil Sensor Product Introduction

Water in Oil Sensor is used to detect moisture and temperature in hydraulic and lubricating fluids, and measures water activity to detect free or dissolved water.Water in Oil 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. Water in Oil Sensor integrates micro-water monitoring technology to detect trace amounts of moisture in the oil, as well as water activity, dissolved water, and temperature, thereby obtaining the oil's health status. Based on our company's years of experience in online oil monitoring, it analyzes the oil health index, assesses the wear and tear of lubricating oil additives, monitors the degree of oil aging, and determines the oil contamination status.

Water in Oil Sensor helps users improve the health management of their equipment assets, assisting in maintenance decisions based on real-time monitoring results and preventing abnormal wear and corrosion caused by oil moisture contamination.

2、Water in Oil Sensor Features

Widely applicable, suitable for all lubricating oils.

Simultaneous measurement of multiple parameters promptly detects water contamination in lubricating oil, helping users to filter ingress water and prevent equipment malfunctions caused by water contamination.

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

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

Highly compatible with CAN-J1939 and RS485-Modbus RTU.

Suitable for monitoring under high-speed flow conditions, suitable for oils of varying viscosities, robust and durable.

Compact design for easy installation.

3、Water in Oil 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.

Water in Oil 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.

Water in 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.
