DNV GL awards component certificate to eologix for pioneering ice sensor system.
Press release from DNV-GL:
DNV GL, the world’s largest resource of independent energy experts and certification body, has awarded eologix sensor technology GmbH (eologix) with component certification for its ice sensor system at the annual EWEA event in Paris. The sensor system is unique to the wind market, providing the first autonomous sensors which exploit the different electrical properties of air, water and ice for icing detection directly on the surface of wind turbine rotor blades.
DNV GL has certified the complete sensor system in line with the guideline GL2010. The design of eologix’s sensor system is based on a newly developed and patented physical measurement system to detect even very thin ice formations at local thicknesses of 1 mm and less.
Eologix’s wireless smart sensor can be placed directly onto the blade of the wind turbine, measuring icing and surface temperature even in locked-rotor state, providing early detection of ice formation from critical blade locations. The sensor signal is sent directly to the to the receiver unit to initiate the necessary measures for optimised operations, i.e. activation of the heating system or switching the turbine off if required, removing the need for a manual operation of the system…
