Magnetic extensometers are precision measurement systems developed to monitor vertical ground movements. This system detects settlement and heave movements in the soil, providing reliable data for long-term stability analyses. Magnetic extensometers are widely used in projects involving dams, tunnels, mining sites, deep excavations, embankments, and slope stability monitoring.
The system consists of magnetic targets embedded in the soil, an access casing, and a specialized probe lowered into the casing. As the magnetic targets move with the soil, the probe takes periodic measurements and records the depths of the targets. This allows for a detailed analysis of soil deformation over time. Regular measurements help track ground settlement or heave movements and enable early identification of potential risks.
Magnetic extensometers are manufactured using durable and long-lasting materials, ensuring maximum resistance to harsh field conditions. Thanks to their easy installation, they can be integrated into existing boreholes or wells. Additionally sensors can be placed within the material during the filling process eliminating the need for drilling.
