Oil Quality Sensor
Oil Quality Sensor
Real time oil condition analysis sensor for all industrial and commercial applications.
OQS delivers the ultimate high-quality real-time oil condition analysis. This enables multiple tangible operating benefits that include reduced maintenance costs, improved reliability, reduced oil wastage, and extended equipment life.
Our unique FSH™ core technology analyses oil condition holistically, detecting, measuring and tracking all and any contamination or wear with 0.01% sensitivity (100ppm) – other sensor systems typically look at specific parameters and ignore others. This unmatched real-time complete oil analysis capability is achieved through continuous analysis of the electro-chemical properties of the oil at a molecular level.
OQS analysis data provides unrivalled high-confidence insight into real-time equipment health and maintenance status. Reliable forecasting and planning of maintenance based upon actual equipment need and thus extended optimised maintenance intervals and reduced cost becomes possible; with the assurance and safety of continuous over-watch that detects any unexpected anomalies and or contamination.
OQS works with any oil type and is easily fitted to any equipment operating in any environment or application.
Technical Specifications
Sense-2 Display Kit
The system continuously analyzes, logs, and displays actual oil condition and remaining oil life in real time. Configurable analytics generate alerts in case of unexpected contamination or oil wear, ensuring timely maintenance actions. With a built-in data logger and wireless connectivity, data can be easily accessed and downloaded for further analysis.
SENSE-2 is a versatile solution suitable for any environment and compatible with all types of oils, offering quick installation and reliable, continuous monitoring.
Key Features
- REAL TIME ANALYSIS – Continuous real-time oil condition analysis with 0.01% sensitivity, detecting and reporting changes caused by wear and or contamination.
- RELIABLE ACCURACY – Our unique molecular level analysis technology means that the smallest changes down to 100ppm are detected and reported in real time. This enables us reliably track oil wear and immediately detect contamination or equipment issues at the earliest stage
- ANY OIL TYPE AND EQUIPMENT – Can be fitted and used on any equipment type operating in any environment using any oil type – mineral or synthetic
- REDUCE MAINTENANCE COSTS – Enables you to predict and pinpoint when equipment requires maintenance and oil is truly at the end of its life. This typically enables you to safely extend intervals between maintenance and reduce associated costs by approximately 30% per year
- REDUCED DOWNTIME – Unseen equipment issues cause subtle changes to oil condition, which are detected and alerted, enabling pre-emptive maintenance before failure or major damage and/or accelerated wear
- ENVIRONMENTAL (ESG) TARGETS – Safely maximise oil use to reduce consumption by approximately 30% per annum. Reduce parts consumption and extend equipment life

Oil Interpreting Guide
Tan Delta technology continuously analyses oil in real time at a molecular level, accurately tracking condition changes as equipment operation causes oil to wear. Rate of change projection enables reliable optimal maintenance forecasting and safe interval increases – thus reduced costs. Contamination or equipment issues cause trend spikes which are instantly detected, enabling immediate evaluation and action as necessary to avoid unnecessary break downs and life-shortening equipment wear.
Have Questions? Get in Touch
What are Oil Quality Sensors (OQS) and what do they measure?
Oil Quality Sensor (OQS) are advanced sensors designed to monitor real-time oil condition inside engines, gearboxes, hydraulics, and industrial machinery. They measure changes in oil chemistry to detect degradation, contamination, and wear-related issues.
How does Tan Delta’s OQS technology work?
The sensors use proprietary Tan Delta technology, which analyzes the dielectric constant of the oil. As oil degrades or becomes contaminated (with fuel, water, soot, or metal particles), its electrical properties change. The sensor detects these changes and provides a continuous oil condition index.
What are the key benefits of using OQS sensors?
Key advantages include:
- Real-time monitoring (no need for manual sampling)
- Early detection of contamination and oil degradation
- Extended oil drain intervals (condition-based maintenance)
- Reduced downtime and maintenance costs
Improved equipment reliability and lifespan
Where can Oil Quality Sensors be used?
OQS sensors are widely used in:
- Automotive and fleet management
- Industrial machinery and hydraulics
- Wind turbines and power generation
- Marine and heavy equipment
They are ideal for predictive maintenance and asset health monitoring.
Can OQS sensors integrate with existing systems?
Yes. OQS sensors support CAN, analog, and digital outputs, allowing integration with ECUs, telematics systems, PLCs, and data loggers. This enables remote monitoring, IoT connectivity, and centralized diagnostics.
