Adjusting guide and rotor blades of Kaplan turbines

Optimum adjustment of impeller to water volume

The solution

With the help of our BTL magnetostrictive linear position sensors, you can flexibly adjust the guide and rotor blades of Kaplan turbines. A BTL profile controls the exact position of the guide blades depending on how much water is to flow into the turbine. In addition to this, our BTL magnetostrictive linear position sensors are integrated into the shaft to adjust the blades of the impeller to the various flow volumes.

The features

• No reference run required after voltage interruption
• Rugged, non-contacting
• High protection class
• Pressure-rated for installation inside hydraulic cylinders
