Bridges & buildings

The very high accuracy of up to 0.01 degrees in roll and pitch for high end NORSUB MRUs make them a great choice for monitoring deflections of bridges and other structures. The onboard MRU real-time FFT analysis is also useful for vibration monitoring.

Wind turbine

For floating offshore wind turbines, it is also necessary to measure the roll and pitch motion caused by the waves as this induces in a big change in the apparent wind speed at the nacelle. These motion measurements can be used by the generator control system to optimize the pitch of the blades in real-time.   …
