1. Energy buffer

Rechargeable battery for buffer function of up to 1000 hours and more (depending on type of application).

2. Energy source

A flexible solar panel ensures practically unlimited energy supply from daylight.

3. Impedance measurement

Ice thickness and other layers, such as dirt, are detected and qunatified directly on the blade surface.

4. Temperature measurement

Surface temperature is measured with an accuracy of 0.25°C.

5. Wireless

The sensor transmits data to the base station with a minimum range of 250m.

Advantages and benefits

  • Exact detection of icing and exact local detection on rotor blade regardless of visibility conditions or access.
  • Sensors and rotor blade heating systems can be used simultaneously for optimal efficiency.
  • Sensors are taped onto rotor blades, no drilling, openings or wires necessary.
  • Completely isolated sensors, no additional risk of lightning strike.
  • Measurement data of icing conditions and temperature formation even during complete standstill.
  • Modular product system from detection to “automatic re-start” (DNV-GL certified).
  • Variable number of sensors per wind turbine for a solution based on your individual needs.
  • No operational data and no calibration during operation necessary.
  • Retrofittable- Savings on operational costs by completing installation during blade inspection!

Maintenance costs and operation is one of the main cost factors of a wind turbine and can make up to 40% of total cost. Rotor blade maintenance alone can account for up to one fifth. The majority of these costs can be traced back to missing or insufficient condition maintenance solutions. Currently the majority of rotor blade maintenance is carried out by industrial climbers who inspect and, if necessary, repair rotor blades. The largest international wind turbine manufacturers emphasize the need for continuous condition monitoring systems, especially for rotor blades.

eoIACC is the first on- blade continuous condition maintenance sensor based on sensors distributed over the rotor blade surface, especially on the blade tips.
