Pitch and blade angle measurement using laser technology

Detect aerodynamic imbalances — avoid damage and downtime

Misadjusted rotor blade angles result in aerodynamic imbalance of the rotor. The result: increased vibration loads on the rotor, drivetrain, tower and foundation. These additional dynamic loads reduce the lifetime of the system, promote damage and cause avoidable downtime.

8.2 carries out pitch and blade angle measurement with a high-frequency, laser-based measurement system — during operation, without loss of yield and with immediately available results.

An overview of our measurement technology

• Laser-based distance measurement during plant operation
• Scanning the pressure-side rotor blade profiles at two radii
• Determination of the relative rotor blade angle differences
• Additional recording of the axial tower vibration
• System use with DEWI-OCC certification

Advantages of the laser measurement process

• Measurement under real operating conditions
• No downtime — no loss of revenue
• Direct evaluation and plausibility check of measurement results on site
• Optional: Immediate adjustment of the rotor blade angles by a qualified service team with appropriate expertise
• Avoiding imbalances, damage and costly subsequent repairs

Why blade angle measurements with 8.2:

With the rotor blade angle measurement of 8.2, you receive reliable data on the aerodynamic orientation of your system — for smoother running, longer service life and better performance.
