With the new sensor platform fos4Blade, fos4X presents a modular and open platform to collect all relevant data from the rotor blades and the tower of a wind turbine. The sensor platform consists of several fiber-optic strain sensors and fiber-optic vibration sensors per rotor blade.

The sensors are monitored by a fiber-optic measurement device developed specially for wind turbines placed in the rotor hub. The fiber-optic measured variables are finally translated by the Blade Physics Library into parameters of the rotor and are provided by fieldbus or IIoT interfaces. Fiber-optic sensor technology is characterized by its insensitivity to lightning strikes and electromagnetic interference.
