Oil dielectric constant sensor

1、Oil dielectric constant sensor Product Introduction

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

Oil dielectric constant sensor uses electrochemical impedance spectroscopy (EIS) to detect the dielectric constant of the oil, thereby determining its health status. Impedance spectroscopy can detect multiple parameters, which can be used to assess the wear and tear of lubricating oil additives, monitor oil aging, and determine oil contamination levels.

Oil dielectric constant 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、Oil dielectric constant sensor Features

Wide range of applications, suitable for all lubricating oils.

Simultaneous measurement of multiple parameters promptly detects lubricating oil contamination and aging, helping users optimize oil change intervals.

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.

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

Suitable for monitoring under high-speed flow conditions, with stronger viscosity interference resistance than similar sensors.

Robust and durable integrated design eliminates the need for external valve blocks, facilitating installation.

3、Oil dielectric constant 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.

Oil dielectric constant 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.

Oil dielectric constant 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.
