What is Shaft Torque Measurement?
The torque measurement system provides the user with information about the torque and compressive forces acting on the shaft. Based on the measurement results, it is possible to analyze how much power is produced and whether it is transferred entirely to the shaft. The effects of the changes made can be read immediately from the meter. This gives the systems great potential for savings.
Typical applications for torque and compression measurements include ship propeller shafts, where the pitch angles have a significant impact on the forces transmitted to the shaft. By optimizing the pitch angles according to sailing conditions and cargo, fuel savings of up to 5% have been achieved. By measuring thrust, it is also possible to monitor the degree of hull fouling and, from a maintenance perspective, plan hull cleaning at an appropriate time in advance.
Selection of Torque Measurement Devices
The technology used in the VAF TT-Sense measurement system has been awarded the Marine Propulsion Fuel Efficiency Award.
In addition to concrete energy savings, the advantage of torque measurement is its easy installation, which can be carried out as part of the ship’s own maintenance work without specialized expertise. The measurement system can be combined with fuel consumption calculation: up to 12 flow meters equipped with temperature measurements can be connected to the system.
