Ensure reliable equipment operation with real-time, multi-parameter oil condition monitoring.
In modern industrial environments, lubricating oil and hydraulic oil are the lifeblood of critical machinery. Unexpected equipment failures caused by oil contamination, aging, or wear debris can lead to costly downtime and expensive repairs. That’s why a professional, real-time oil monitoring strategy is essential.
We offer a complete sensor-based solution that complies with international standards — including ASTM D8184 — and is suitable for all types of oils and greases.
Gear Oil Monitoring – Focus on Wear Debris & Oil Aging
For gearboxes, wear condition is the primary concern, while oil aging and contamination must also be monitored to fully assess equipment health.
Recommended sensor combination:
YFM-8 Wear Debris Sensor + YTS61 6in1 oil condition Sensor
-
YFM-8 detects ferrous and non-ferrous wear particles, capturing early signs of gear or bearing damage such as pitting or spalling.
-
YTS61 simultaneously monitors viscosity, density, dielectric constant, dissolved water, water activity, and temperature — identifying oil aging, moisture ingress, and contamination trends at an early stage.
This combination enables synchronized, multi-parameter monitoring to provide a complete picture of gearbox health.
Hydraulic Oil Monitoring – Focus on Cleanliness & Moisture
For hydraulic systems, oil cleanliness and water content are critical factors directly affecting component lifespan and operational stability.
Recommended sensor combination:
YFJ-4 Particle Counter + YTS61 6in1 oil condition Sensor
-
YFJ-4 monitors particle contamination in real time, helping prevent valve sticking, component scoring, and other faults.
-
YTS61 provides ongoing status of oil aging, moisture, and other key parameters.
With real-time data feedback, the system delivers precise support for health assessment and maintenance decision-making, avoiding common hydraulic failures.
Best Practices for Oil Sampling Points
Proper sampling point selection ensures that oil samples truly represent the actual operating condition of the equipment.
Basic Principle:
Select a sampling location as close to the equipment as possible — ideally from the lubrication system near the machine.
Hydraulic System Sampling Guidelines:
-
Preferred choice: Use the professional sampling port on the oil tank for representative samples and easy operation.
-
Alternative: If no dedicated port exists, install a sampling point at the tank breather, positioned at approximately 1/3 of the oil level height to avoid stratification effects.
-
Avoid high-pressure pipelines – hydraulic systems often operate above 10 MPa; sampling from high-pressure lines is dangerous and leads to unrepresentative results.
-
Avoid return lines – pressure fluctuations and pulsations in return lines due to intermittent pump operation can distort measurement accuracy.
Return Line Selection:
-
The return line should typically lead to a zero-pressure point in the tank.
-
Ensure smooth oil return without interfering with normal equipment operation.
-
Avoid oil splashing, foaming, or disturbance that would affect oil settling performance.
Why Choose Our Sensor Combination?
We recommend the YFM-8 Online Wear Debris Sensor paired with the YTS61 Six-in-One Sensor to form a comprehensive oil condition monitoring system.
