Borehole Rod Extensometer Geo-XB2 Series
The Geo-XB2 Borehole Rod Extensometer is a high-precision instrument designed to measure ground and rock mass deformation at various depths within a borehole. Built for long-term geotechnical monitoring, this system provides accurate displacement measurements that help engineers understand subsurface movement, structural stability, and the behavior of geological formations over time.
The Geo-XB2 uses rigid fiberglass or stainless-steel rods connected to anchor points installed at selected depths. Any displacement—whether settlement, heave, bending, or shear movement—is transferred directly to the surface readout, allowing engineers to track both incremental and cumulative changes. Because of its robust design and mechanical simplicity, the system delivers stable, drift-free performance even in harsh environments.
This extensometer is widely used in tunnels, deep excavations, slopes, mines, dams, and infrastructure construction projects. It supports continuous monitoring through automated dataloggers or manual measurement using portable readout devices. The Geo-XB2 system is compatible with multi-point configurations, enabling simultaneous measurement of deformation profiles across different layers.
Built to meet global geotechnical monitoring standards, the Geo-XB2 Series offers long service life, excellent corrosion resistance, and reliable operation under variable geological conditions. It delivers the clarity and consistency required to support data-driven engineering decisions, ensuring safer and more predictable project outcomes.
