During the lifetime of a wind turbine, the blade bearings are exposed to dynamic forces that can lead to damage such as cracks. Depending on the progress of the damage, cracks in the blade bearing can lead to rotor blade loss. The TwinCap® sensors from Weidmuller provide information on the condition of the blade bearing.
Expert condition monitoring for onshore and offshore
Optimise turbine availability and make service calls plannable with BLADEcontrol® rotor blade monitoring,TwinCap® screw monitoring for blade bearings and BOLTcontrol bolt breakage detection system.
Inspection intervals can be extended by using our TÜV-certified blade bearing monitoring system with TwinCap® sensors. This reduces the cost of visual inspections on site and avoids profit losses.
As soon as a screw nut bursts, it expands. The TwinCap® sensor detects this change and interrupts the circuit. The evaluation unit has various interfaces for signal forwarding. The damage can then be checked and repaired to prevent further consequential damage.
The monitoring system can be integrated into the failure loop of the wind turbine to ensure a safe shutdown of the wind turbine in case of a damage event.
Up to 80 sensors can be integrated in series. They are fixed in place by magnets, so that they can be mounted and dismounted without tools. Connection to the evaluation unit is via conventional analog inputs.
The extremely robust, encapsulated sensors are insensitive to environmental influences such as vibrations, temperature fluctuations, humidity, or salty air and are therefore even suitable for offshore applications.
Called Twin Cap® , this innovative system uses sensors over the nuts located on the outer ring of the blade bearing and connects them in a serial topology (daisy chain). If a blade bearing crack spreads from the bearing surface into the nut causing it to crack with a minimum expansion of 2mm, the system detects the broken nut, and can alert the pitch system to initiate a controlled and safe shut down.
