Introduction
For hydraulic systems, gearboxes and power units across all industrial sectors, most premature equipment wear stems from unnoticed lubricant degradation. Deteriorated viscosity, water ingress, oil oxidation and contamination do not trigger immediate shutdowns, yet they steadily erode precision components. The end result? Unexpected breakdowns, costly spare part replacements and crippling production downtime.
Traditional offline lab oil sampling comes with unavoidable delays—you can never capture sudden oil degradation trends in real time. Separate multi-sensor setups, on the other hand, require complicated wiring and high installation costs, making them impractical for compact machinery enclosures.
The Yateks YTS61 6-in-1 Oil Condition Sensor eliminates these pain points. This single compact probe measures six critical oil parameters simultaneously and delivers 24/7 continuous in-line monitoring. It delivers a lightweight, highly reliable predictive maintenance solution for manufacturing, construction machinery, marine vessels, wind turbines and more.
All-in-One Detection: Track 6 Core Oil Health Metrics from One Device
Unlike ordinary sensors that only capture 1 or 2 indicators, the YTS61 integrates multi-dimensional sensing technology to deliver a full picture of lubricant condition in real time:
- Viscosity: Reflects oil thinning/thickening caused by oxidation and high temperature
- Temperature: Identifies abnormal operating heat that accelerates oil aging
- Density: Detects fuel dilution, particle contamination and fluid degradation
- Dielectric Constant: Quantifies oxidation levels and foreign impurity buildup
- Water Activity: Predicts risks of emulsification and metal corrosion
- Moisture Content: Directly measures free and dissolved water in lubricant

Every metric is transmitted live to your control system, allowing maintenance teams to spot subtle oil deterioration long before it harms valuable assets. No more guesswork, no more delayed lab reports.
Built for Harsh Industrial Operating Environments
Engineered with rugged stainless steel housing, the YTS61 withstands vibration, temperature fluctuations and dusty, humid factory conditions. Its streamlined threaded design enables fast, direct installation on gearboxes, hydraulic tanks and engine oil circuits without extensive modification.
One sensor replaces multiple single-function monitors, drastically cutting hardware costs, wiring labor and system integration complexity. It seamlessly connects with PLC, industrial IoT gateways and condition monitoring platforms, fitting perfectly into new smart manufacturing upgrades and retrofitting old equipment alike.
Drive Down Costs & Maximize Asset Lifespan with Predictive Maintenance
Unplanned downtime is one of the biggest financial burdens for industrial operators. The YTS61 turns reactive maintenance into proactive predictive maintenance:
- Early warning of oil contamination and water intrusion to prevent component corrosion and abrasion
- Optimized oil change cycles: Replace lubricant only when it truly degrades, cutting oil waste and consumable expenses
- Continuous real-time data eliminates the need for frequent manual sampling and lab testing fees
- Minimize unplanned shutdowns, extend the service life of expensive machinery and reduce long-term repair overhead
Final Word
The Yateks YTS61 6-in-1 Oil Condition Sensor is more than a monitoring device—it is a core upgrade for your industrial reliability strategy. Gain full, instant visibility into your lubricant health, mitigate equipment failure risks, and unlock measurable operational efficiency gains.
