Oil viscosity sensor

1、Oil viscosity sensor Product Introduction

Oil viscosity sensor is used for real-time, online monitoring of lubricating oil viscosity, density, and temperature. Continuous monitoring of the oil's condition improves condition-based maintenance efficiency, optimizes oil change intervals, and reduces reliance on offline analysis.

Oil viscosity sensor integrates ultrasonic viscosity monitoring technology to detect oil viscosity, density, and temperature, thereby determining 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 consumption, monitors oil aging, and determines oil contamination levels.

Oil viscosity 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 viscosity sensor Features

Widely applicable, 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 problems.

Diagnoses challenging issues and includes built-in health index analysis.

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

Highly compatible with RS485-Modbus RTU and RS232.

Suitable for monitoring under high-speed flow conditions; exhibits stronger viscosity interference resistance than similar sensors; robust and durable.

Utilizes tuning fork resonance technology for high precision, long-term stability, and no moving parts.

3、Oil viscosity 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 viscosity 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 viscosity 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.
