The Structural Health Monitoring System from Dewesoft delivers a purpose-built solution for permanent monitoring of civil and industrial infrastructure. Built around the IOLITEi-3xMEMS low-noise triaxial MEMS platform. Firstly, the system captures high-quality vibration, displacement, velocity, and inclination data to reveal how structures behave over time.
As a result, engineers and asset owners gain clear insight into structural performance, emerging issues, and long-term trends.
