Optical Torque Measuring systems

The use of a T-Sense® torque measuring system means efficiency improvement, overload protection and prevention of breakdown. For example in the shipping industry its application has lead to savings up to 10% on fuel costs. The system is based on extremely accurate optical sensor technology and can be easily mounted around shafts in power transmission systems. The T-Sense® measuring system can be mounted on propeller or drive shafts. When a shaft is subject to torque this will result in a small strain at the shaft surface. A LED and an extremely accurate optical cell can detect these small movements...

Applications of torque measurement By using the T-Sense® measuring system, the performance of the engine and ship’s propulsion can be measured separately providing an important input to fuel saving and maintenance investment decisions. Customers have reported savings of up to 10% on fuel costs by managing fuel consumption and engine performance at full scale. In combination with a monitoring or management system, such as VAF Instruments PEM2, PEM4 or IVY®, the T-Sense® measuring system can be used in a variety of applications. The benefits of measuring torque: - - - - - - - Determines ship’s...

The T-Sense® torque measuring system can be combined with the PEM4 Propulsion Efficiency Monitor, the vessel’s monitoring system and/or IVY® Propulsion Performance Management Solution to use the T-Sense® to its full potential. IVY®, VAF Instruments’ solution for Propulsion Performance Management, brings you the fleet at your fingertips. From ship to shore, IVY® enriches big data for powerful analysis. The web application of IVY® provides fleet and ship performance visualisation and insight into the relevant data and more than 30 KPIs. IVY® can be combined with a range of sensors on board, including...
