  • Reliability

    Reliability, availability, maintainability and security (RAMS) are our top priorities. In many hundreds of years, our fiber optic sensors have proven to be more reliable than electrical sensors for rotor blade sensing. Lightning strike, EMI and high load cycles are not an issue. Maintenance-free operation over 25 years, remote control capability and emphasis on aspects of functional safety complete the range.

  • Innovation

    Together with the Blade Physics Library, our fiber optic measuring system fos4Blade allows to calculate all relevant structural parameters in the rotor blade. These smart data are accessible via open interfaces. Our unique fiber-optic measuring technology is the technological foundation for future digital business models for optimizing the operation of wind power plants.

  • Cooperation

    We work very confidently with the largest and most innovative manufacturers of wind turbines. We are now series suppliers of Senvion and Nordex and are integrating our measuring system fos4Blade with several other turbine manufacturers in the series. Technical, procedural and commercial aspects play important roles, but the focus is always on personal relationships.
