Vibration Monitoring

The art of measuring low-frequency vibrations

17 08 15 3The art of measuring low-frequency vibrations

Rotor blades in wind turbines are growing longer – but also slower.

Multimegawatt wind turbines turn even more slowly. This means that reproducible low-frequency vibration monitoring will gain in importance not only for the main rotor but also for the slow-operating gearbox components and roller bearings. Reliably measuring low frequencies, however, can be rather tricky.

There are some notable aspects, which also pose new challenges to sensor and measurement hardware manufacturers.
The following presents how PRUFTECHNIK Condition Monitoring GmbH is testing new products in its own test facilities as well as in wind turbine field trials.
