Torsion Measurement and Axle Power
Torsion measurement measures how much a shaft twists, i.e. the torque. Once the torque is known, it is possible to calculate the precise power when the shaft dimensions and rotational speed are known.
In addition to verifying shaft power, the technology can also be used to measure torsional vibrations and even be used for fuel optimisation!
Sea Trials
When building new ships, the power output of the propeller shaft must be measured. This is done before taking delivery of the ship on a sea trial to ensure that the ship can perform as required.
This may also be in connection with a shipyard stay, including possible renovation of the engine or gearbox. In this case, it is a good idea to verify that the engine still has the same power. A kind of acceptance test before taking delivery of the ship from the shipyard again.
Whether it is a large main engine with 100,000 hp or a smaller generator or perhaps a PTO shaft output, our technicians are ready to assist you with high-quality measurements within shaft power measurement.
Fuel optimisation
The more energy a ship can extract from fuel, the greater its fuel efficiency. There is currently a strong focus on reducing fuel emissions from vessels, but to do so requires data.
If stationary equipment is used to measure the actual shaft power and compare it with the ship's speed and fuel consumption over a period of time, it is possible to see when the ship is using too much fuel in relation to the power delivered to the propeller shaft.
Product range
We offer quality products from one of the world's leading suppliers of torsion measurement equipment, the American brand Binsfeld. This enables us to offer both portable and stationary wireless torsion measurement equipment.
With a portable solution, a strain gauge sensor is mounted on the axle and connected to a small wireless transmitter (battery-powered) that sends data wirelessly directly to a receiver next to your PC. You can follow the values live on the screen, and graphs of speed and effects are generated automatically.
With the latest stationary torsion measurement equipment from Binsfeld, it is possible to connect the sensor on the shaft to a transmitter in the same way. This contains batteries in the entire collar around the shaft, which can last for up to 1 year. It couldn't be easier – no more expensive installation costs for permanently mounted torsion measurement equipment!
