Oil Level Sensor

1、Oil Level Sensor Product Introduction

Oil Level Sensor can monitor oil moisture, free water, dielectric constant, and liquid level, enabling simultaneous monitoring of multiple parameters and optimizing oil change intervals.Oil Level Sensor is used for real-time, online monitoring of oil tank level changes and lubricant health. Continuous monitoring of the oil condition improves condition-based maintenance efficiency, optimizes oil change intervals, and reduces reliance on offline analysis.

Oil Level Sensor employs unique level detection technology and electrochemical impedance spectroscopy (EIS) to detect the oil's impedance spectrum, thereby obtaining the oil's health status. Impedance spectroscopy can detect multiple parameters and can be used to assess the wear and tear of lubricant additives, monitor oil aging, and determine oil contamination levels.

Oil Level 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 leaks, oil aging, or contamination.

2、Oil Level Sensor Features

Wide range of applications, suitable for all lubricating oils

Simultaneous measurement of multiple frequencies and parameters promptly detects changes in oil levels, as well as oil contamination and aging, helping users optimize oil change intervals.

Big data oil analysis algorithms help customers solve diagnostic challenges.

24/7 uninterrupted monitoring provides timely feedback on oil quality and tank level status.

Strong compatibility, compatible with CAN-J1939 and RS485-Modbus RTU, 4-20mA output.

No moving parts, robust and durable.

Compact and lightweight, easy to install.

3、Oil Level Sensor Application areas

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

Oil Level Sensor can continuously monitor the oil tank level and the degree of oil aging and contamination 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.

Oil Level 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. Applications include: wind turbine gearboxes, aircraft/helicopter gearboxes, hydraulic transmission systems, machining centers, steam turbines, gearboxes, electric vehicle motor cooling equipment, and gasoline/diesel engines.
