Condition monitoring for bolted joints

Detect anomalies and deviations in your screw connections. Our condition monitoring systems provide the relevant information early and reliable.

Condition monitoring for bolted joints

Bolts are one of the most stressed parts of a wind turbine

During the life time of a wind turbine, bolts suffer from dynamic forces which can result in cracks, damages and breakages. For a safe and reliable operation of the wind turbine, every single bolt must be intact. The bolt monitoring systems from Weidmüller provide a necessary information about the condition of each bolt at the rotor blade or tower segment connection.

Elevate your blade performance

Expert condition monitoring for onshore and offshore

Optimise turbine availability and make service calls plannable with BLADEcontrol® rotor blade monitoring and TwinCap® screw monitoring for blade bearings.

Your benefits with our bolt monitoring solution

Monitoring of bolted joints

Monitoring of bolted joints

By integrating a Weidmüller condition monitoring solution, you know the status of your bolted joints on the tower segments, the foundation or the blade bearing.

Reliable damage detection

Reliable damage detection

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.

Prevention of further damages

Prevention of further damages

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.

Flexible integration

Flexible integration

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 analogue inputs.

Wide range of applications

Wide range of applications

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.

Our offering

Evaluation Unit

The evaluation unit collects the sensor data and processes it using an integrated controller. It forms the interface to the main controller. The data can optionally be provided via remote access in the SCADA.

Evaluation Unit
Your advantages
  • Customized housing for every type of wind turbine
  • Simple integration into the wind turbine, e.g. as retrofit
  • Turnkey solution consisting of sensors, signal evaluation and suitable interfaces

TwinCap® sensors Product innovation

Over the course of operating time, cracks, damage and fractures can occur in bolt nuts. The TwinCap® system reliably detects such signs of wear and can thus prevent costly consequential damage.

TwinCap® sensors
Your advantages
  • Protection class IP68 for outdoor use
  • Quick mounting and demounting via magnets
  • Low wiring effort due to series connection
  • Integrated LED for visual detection of damaged nuts

Our whitepaper about blade bearing monitoring with TwinCap® answers the following questions:

  • When and why should you use condition monitoring for blade bearings?
  • What are our TwinCap® sensors and what are their advantages?
  • When is blade bearing monitoring useful for you?
