Structural Health Monitoring

Hear the damage before it becomes visible

Monitor bridges and technical installations safely – with acoustic emission monitoring

Early damage detection for long-lasting infrastructure

Bridges are the backbone of modern transport infrastructure – and at the same time are exposed to extreme stresses from traffic, weather and ageing. With Structural Health Monitoring (SHM) using Acoustic Emission (AE), we offer a high-precision, continuous monitoring solution that detects damage before it becomes critical.

What is acoustic emission?

Acoustic emission uses high-precision sensors to record the elastic waves that occur when stress is released in the material – for example, during tension wire breaks, crack formation or progression, or corrosion. These signals provide real-time information about the location, type and intensity of damage.

Application of the sensor network at selected hotspots

Typical applications

Prestressed concrete (tension wire break detection)
Steel bridges (crack formation and progression)
Structures with known weak points or a history of repairs reinstatement
Monitoring during and after repair a full reinstatement work
Heat storage tanks
Flat-bottom storage tanks
Low-temperature storage tanks for liquefied gases

How it works:

Creation of AE measurement concepts
Implementation planning for AE measurement systems
Installation of sensors at key points of the structure
Data acquisition of acoustic emissions caused by material changes
Analysis and interpretation using intelligent algorithms and experts
Alarm & amp; reporting when defined thresholds are exceeded

Our qualifications:

– Data analysts for acoustic emission analysis with AT2 and AT3 certification according to DIN EN 9712

– Concept and implementation planning in accordance with DGZfP guideline SE 05 ‘Detection of tension wire breaks using acoustic emission analysis’

– Building inspection in accordance with DIN 1076
