Description
Autonomous sensor with probes; they are linear potentiometers measuring extremely small displacements.
They measure the cracks evolution or the contraction or joints extension.
Combined, several sensors can be used to monitor cracks in 3D.
Each sensor is autonomous; it does not need another box or a sending station
Applications
Monitoring in buildings, bridges, pipelines, dams.
