Basic measurement setup, onshore or offshore
The ROMEG System is available as ground and nacelle version.
Ground measurement
During ground measurement, the laser beams are directed in the vertical tower plane to a point near the blade tip and a point at the greatest profile depth of the rotor blade. During each blade pass, the profile contours are scanned and the times between the individual blade passes are determined.
Between the blade passes, the axial tower vibrations are recorded.
Nacelle measurement
During the nacelle measurement, the laser beam is directed at the 12:00 position of the rotor blades. While measurement, the blade contour is scanned with each pass and the times between the passes are recorded.
The tower vibrations are recorded via a 2-axis acceleration sensor.
