Precision in motion■
Precision in motion. On every shaft, at every moment.
In naval operations, propulsion performance is mission critical. The T-Sense® Optical Torque Measurement System delivers continuous, real-time insight into torque, shaft speed, and power output. Data that naval engineers and officers depend on to drive efficiency, safety, and readiness.
Designed for the uncompromising environment at sea, T-Sense® is built with rugged optical technology, non-contact power and signal transfer, and zero moving parts. That means no maintenance, no calibration, and no surprises.
When integrated into onboard monitoring systems, T-Sense® becomes more than a sensor, it becomes a force multiplier. With accurate propulsion data available instantly, commanders can balance loads, optimize fuel consumption, detect anomalies early, and make better decision under pressure.
Real-Time Torque Insight
See exactly how your propulsion system performs, instant torque, speed and power feedback.
Maintenance-free Reliability
Non-contact optical sensing ensures continuous operation with zero wear or recalibration.
Fuel & Load Optimization
Use live performance data to fine-tune engine load and cut fuel costs.
Fleet-Wide Integration
Seamlessly connect T-Sense® with PEM4, IVY® or AMS for complete propulsion performance control.
WE PRESENT:
T-Sense®■
T-Sense® is VAF’s naval-grade optical torque measurement system, engineered to give naval engineers full control over propulsion performance. Mounted directly on the shaft, it captures the true mechanical output of the drive line, independent of fuel flow or engine settings. This makes it an essential tool for verifying propulsion efficiency, safeguarding assets, and supporting data-driven decision-making throughout the vessel’s lifecycle.
Key features:
- Measures micro-deformations on the shaft surface for real torque accuracy
- 2.4 GHz wireless link with fully protected signal loss
- Continuous, contactless power supply with zero signal loss
- Configurable for diameters from 100 mm to 1000 mm
- Operates reliably from – 10°C to + 60°C in high-vibration zones
- Modbus RS-485, Ethernet, or 4-20 mA for seamless integration
- Verified performance under classification and MIL-standard condition
Ensure Low Operating Costs
T-Sense® delivers measurable savings across the vessel’s lifecycle, reducing both fuel consumption and maintenance demands.
