Oil Pressure Sensor

1、Oil Pressure Sensor Product Introduction

Oil Pressure Sensor provides 24-hour continuous monitoring, providing real-time feedback on oil level and pressure in the oil tank, thus improving the health of the lubricating oil and equipment.Oil Pressure Sensor is used for real-time, online monitoring of lubricating oil health and level. Continuous monitoring of oil condition improves condition-based maintenance efficiency, optimizes oil change cycles, and reduces reliance on offline analysis.

Oil leakage is a major cause of abnormal equipment wear; oil level monitoring provides timely alarms for abnormal oil levels.

Oil Pressure Sensor integrates electrochemical impedance spectroscopy (EIS) technology to detect oil impedance spectra, ultrasonic viscosity monitoring technology to detect oil viscosity and density, and micro-water monitoring technology to detect trace amounts of water and water activity. It can also monitor dissolved water 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 and tear of lubricating oil additives, monitors the degree of oil aging, and determines the oil contamination status.

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

3、Oil Pressure 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 Pressure 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 Pressure 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.
