Hydraulic pitch control for turbine blades

High-reliability position feedback for pitch control cylinders

The solution

Reliable turbine blade pitch control is essential for speed regulation, peak energy production, and safe operation. An extensive worldwide installed base is testament to the dependability of Balluff's magnetostrictive linear position cylinder sensors. These hydraulic pitch control sensors undergo rigorous in-house destructive testing during development. Analysis of test specimens reveals potential high-stress failure modes, which are subsequently designed out of the final product. Balluff's expertise in developing robust linear position sensors has lead turbine manufacturers the world over to trust Balluff as the preferred hydraulic pitch control sensor supplier.
