Q-Bo® – Wirelessly Monitor Screws – Rental Evaluation Kit

A loose bolt can cause millions in damage – but who checks thousands of critical connections every day?

In wind turbines, on bridges, in cranes and industrial plants, bolted connections literally hold everything together. Their preload force determines safety and function. But this force gradually diminishes – due to vibrations, temperature fluctuations and material fatigue. Manual inspection with torque wrenches is time-consuming, dangerous and often impossible. Who climbs 100-metre wind turbines every week?

Q-Bo® makes bolt monitoring intelligent, wireless and autonomous. The system continuously measures the preload force directly on the bolt – not estimated, not interpolated, but measured in real time. Temperature and vibration are recorded in parallel. Not only can you see that something is loosening, you can also understand why.

The revolutionary energy harvesting technology eliminates the need for an external power supply. A small solar cell is sufficient for continuous operation. In concealed installation positions, a thermoelectric generator takes over the supply from temperature differences. Alternatively, the system can run for years on a battery. No cables to lay, no power failures to fear.

Retrofitting is ingeniously simple: the sensor-equipped washer replaces the standard washer under the screw head. No drilling, no welding, no conversion. Your existing DIN screws become intelligent sensors. Installed in minutes, monitored for years.

The mioty® wireless protocol from Fraunhofer IIS guarantees reliable data transmission even under the most difficult conditions. Telegram splitting technology achieves virtually zero packet loss even in the presence of strong interference. A single base station manages thousands of sensors – perfect for large infrastructure projects. With up to 3.5 million data packets per day, you can capture every change.

The rental evaluation kit gives you everything you need for immediate testing:

You receive a complete system – from the sensor-equipped screw system to the base station and software. Particularly valuable: the personal online setup appointment with our experts. No studying manuals, no trial and error attempts. A specialist guides you through installation and configuration, answers your questions and shows you best practices. So you can start with the certainty that you are doing everything right.

Remote maintenance revolutionises your maintenance strategy. Instead of expensive routine inspections, you only receive alerts when there are real problems. The maintenance crew drives directly to the loose bolt, not to a routine check. Downtime decreases, safety increases and costs fall.

The areas of application are critical and diverse: bridges with thousands of bolt connections are monitored continuously. Wind turbines report loosening before vibrations cause damage. Cranes warn of critical prestressing force losses. Railway systems detect dangerous rail connections. Wherever bolts are safety-relevant, Q-Bo® makes them intelligent.

The rental system gives you maximum flexibility. You can test the technology without any investment risk, evaluate the benefits for your specific application and gather experience with real data. The rental period is flexible and can be extended if necessary.

Rent our Q-Bo® evaluation kit now and transform your maintenance strategy. Experience the future of bolt monitoring – wireless, autonomous, intelligent.
