Application
Wind energy is used all over the world as a clean energy source. Glass fiber and carbon fiber composites have become established as materials for the rotor blades of wind turbines. These combine essential characteristics such as high strength, low weight and long service life.
The rotor blades are not molded in one piece. The top and bottom sides are each cast separately and then joined together to form a unit by a bonding process. Adhesives made of glass fibre, carbon fibre, silicone and other composite materials are used. These are highly viscous and abrasive. The aim is to achieve a fast and sustainable bond – a challenge for measurement technology. Even the smallest errors can lead to serious additional costs.
Solution
KEM Helical Flow Meters (SRZ Series) withstand extensive abrasion forces and provide accurate measurement data even at high viscosities. A special metrological bearing concept ensures precise measurement results, high reproducibility and long service life.
