Solutions for ice detection


Autonomous sensors  

Autonomous sensors

  • Icing on the rotor blades does not just lead to hazards for the wind turbine generator, but also to dangers to the environment and persons.
  • Phoenix Contact provides a reliable ice detection system for rotor blades for increasing the yields of your wind turbine generators.
  • Our solution measures the coating thicknesses of potential ice deposits and the temperature directly on the surface of the rotor blade.


In order that wind turbine generators can achieve maximum yields, a trouble-free system status must be guaranteed. Under extreme climatic conditions, however, ice can form on the rotor blades. Falling blocks of ice can cause significant damage. The early detection of ice accretion is important in ensuring that the system can be stopped in the event of danger and that the de-icing system can be started.


Control cabinet, ice detection  

Evaluation unit as a complete control cabinet solution

The ice detection system from Phoenix Contact measures the severity of ice accretion on the rotor blades and ensures the reliable operation of the wind turbine generator.

The evaluation algorithm, certified by the DNV GL accreditation company, decides whether to allow continued operation or to shut down the wind turbine generator.

The sensors, which are simply stuck on, measure the coating thickness of the ice as well as the external temperature on the rotor blade. The sensor is supplied directly with solar power and has a storage capacity of up to 1000 hours.

The sensor signals are transmitted wirelessly to the evaluation unit in the nacelle. Here, the wireless range is up to 250 meters. With an appropriate number of sensors, the system is suitable for the automatic restart function. The evaluation unit is available as a complete control cabinet solution or as a system for integration.

Innovative retrofit solutions – Greater efficiency for wind turbine generators

Ice detection retrofit  

Suitable for simple retrofitting

Thanks to the wireless integration of the sensors, the system is suitable both for new wind turbine generators and for retrofitting into existing systems.

Optimize your wind turbine generators with innovative retrofit solutions. Phoenix Contact is the reliable partner at your side to optimize maintenance services on your generators and to sustain the increase of your yields.
