Acquisition of tower oscillation

Despite careful design and workmanship, oscillations occur during the operation of wind turbines; these oscillations continuously subject the structure and materials to mechanical stress.

Lenord + Bauer has developed a special sensor that measures the tower oscillations in real time and transmits the measurements via either a CANopen or EtherCAT interface to the system control. If the stipulated limits are exceeded, the system can be shut down via a safety relay integrated into the sensor.

Advantages of Lenord + Bauer oscillation sensors:

Can be integrated into existing safety systems
Mature, micro-electro-mechanical system (MEMS acceleration sensors)
Robust sensors that are not subject to any ageing whatsoever and
that operate completely maintenance-free and wear-free
Straightforward integration into EtherCAT or CANopen networks
Dew-point resistant, compact design
Redundant measuring system due to comparison of two
acceleration sensors integrated into the sensor
