Turning Into a Favorable Wind


Accurate and Reliable Positioning

Many measuring and positioning tasks must be solved in wind turbines: in addition to yaw control of the nacelle through azimuth drives, the tilt angle of the rotor blades must be monitored and – if necessary – adjusted by means of pitch control systems. POSITAL offers an extensive one-stop range of sensors that withstand even extreme environmental conditions.

Accurate Azimuth Feedback

Optical absolute encoders with a maximum resolution of 16 Bit used in absolute position measurement for azimuth control systems are one example. In addition to high resolution, such applications also require very robust sensors especially at high wind forces. With a shaft load capacity of up to 300 N, POSITAL encoders are among the best options for the aforementioned tasks. The robust, tried-and-tested absolute encoders ensure better reliability and operating safety, which helps users considerably reduce monitoring and maintenance costs.

  • Precise Yaw Drive Monitoring
  • Optimum Wind Turbine Utilization
  • Designed for Harsh Environment

Reliable Pitch Control

Magnetic absolute encoders are used to precisely determine angles for the pitch control system. A high IP class is a key requirement, especially in offshore wind turbine parks where unsteady, very extreme conditions prevail. POSITAL provides ideal models with durable, salt-spray resistant IP69K housings for these tough environments. Based on innovative magnetic technology without gears or batteries, the encoders are very compact and therefore easy to install in limited spaces. Since these models employ a measuring process that is completely wear-free, they are also very durable and withstand temperature changes, shocks, and vibrations.

  • Reliable Rotor Blade Positioning
  • Increased Efficiency
  • Designed for Limited Installation Space
