STRUCTURAL HEALTH MONITORING

As soon as the foundations are laid and all along the lifespan of an infrastructure, the Sensorlines solution in Structural Health Monitoring (SHM) empowers the monitoring of structural performance and behavior—protecting infrastructure integrity and public safety.

Objectives

• Optimize safety of the structure, population, and environment
• Ensure functionality, regulatory compliance, and extend operational lifetime
• Reduce operation and maintenance costs

Distributed Fiber Optic Sensing Advantages

• Much more cost-effective than traditional multi-sensor setups
• Simple—deployment of a single fiber sensor is often sufficient
• Leverages existing fiber optic cables
• Achieves continuous monitoring
• Provides highly localized spatial and temporal data

Sensorlines Interrogators Provide Measurements of:

• Strain and temperature via Sensorlines G1-D (DSTS), G1-C (portable), and G1-R
• Vibrations via Sensorlines A1 (DAS)
• Temperature via Sensorlines T1-R (DTS)

Device Benefits

Our devices integrate seamlessly with supervision systems, and—whether housed indoors or outdoors—deliver accurate, resilient performance even in the harshest conditions:

• Resistant to vibration and extreme temperatures
• Dust- and splash-proof
• Electromagnetic radiation immunity
• Long-term measurement stability
