Altosens makes bolted joints smart—for scheduled maintenance and higher uptime.

Wind turbines contain thousands of bolted joints—at rotor blades, towers, and foundations. These joints are subjected to wind, vibration, and temperature cycles and must be inspected regularly. Altosens enables continuous monitoring of safety-critical bolted joints, allowing maintenance to be planned more precisely and significantly reducing downtime. The altosens.system consists of altosens.disc, altosens.edge-ai, and altosens.analytics.

altosens.disc

The key component replaces a DIN-standard washer and measures where forces occur: directly at the bolted joint. Compact, precise, and retrofit-capable—without modifying existing components.

With altosens.disc, every bolted joint becomes a data source. This enables continuous condition monitoring with minimal additional effort. Operators detect deviations early, avoid downtime, and increase asset availability.

• Washer with forcesensor. Measures preload and axial forces during operation.

• Available from M20. Standard DIN-washer geometry makes retrofits especially simple. Rugged design with high overload capacity.

• Communication via CAN bus interface.

altosens.edge-ai

Collects measurements from multiple sensor washers, processes them locally, and reliably transmits relevant information to existing systems or to the cloud.

altosens.edge-ai simplifies installation and operation. It reduces data volume through intelligent preprocessing, ensures reliable communication, and enables seamless integration into existing IT and OT environments. The result is a comprehensive, actionable picture of the entire system from individual measurement points.

• Integration of multiple altosens.disc sensors.

• Edge computing: on-module preprocessing.

• Communication via CAN bus plus flexible interfaces for local networks and cloud connections. Scalable from individual bolted joints to complex plants.

altosens.analytics

The altosens.analytics platform consolidates all data—clear, intuitive, and available at any time.

With altosens.analytics, you keep critical joints in view at all times. Deviations become immediately visible, risks are identified in time. This makes maintenance plannable—and predictive maintenance a lived reality.

• Online platform for monitoring and analysis; access from anywhere, on any device.

• Real-time visualization of preload and forces.

• Customizable alert thresholds and automatic notifications in case of deviations.
