Description
Autonomous sensor with waterproof displacement probes; these robust probes, operating under water, are not sensitive to vibration or misalignment.
They measure the cracks evolution or the contraction or joints extension.
Combined, several sensors can be used to monitor cracks in 3D.
This sensor is very robust and works in harsh environments.
Each sensor is autonomous; it does not need another box or a sending station
Applications
Monitoring in buildings, bridges, pipelines, dams.
