Health monitoring of wind turbine blades
This is a case study on structural health monitoring of wind turbines using fiber optic sensors. The sensors can be installed without issues during the manufacturing stage, and the system provides real-time data even during the winter months. Monitoring of the blades allows for the assessment of static and dynamic loads, temperature effects, blade distortion (misalignment), and vibrations (frequency and modal response). During operation, data acquisition and analysis were possible from all systems. For more details, please download the catalog or contact us.

Company information
Are you troubled by issues with lightning surges? Fiber optic sensors are insulators, so they will not be damaged by surge currents. Are you struggling with electromagnetic noise? Fiber optic sensors are completely unaffected by electromagnetic noise. Are you required to have explosion-proof and non-flammable features? Fiber optic sensors do not use electricity, so explosion-proof certification is not necessary (they are exempt). Are you facing challenges with complex wiring? Fiber optic sensors can be configured with multiple sensors on a single fiber. Our company offers multi-point measurement solutions using fiber optic sensors, specifically FBG (Fiber Bragg Grating) and communication technology WDM (Wavelength Division Multiplexing) for optical sensing systems (measuring instruments, sensors, software).
