In Place Inclinometer-Extensometer

he In Place Inclinometer–Extensometer (IPI-EX) combines two powerful monitoring technologies into one integrated solution: tilt measurement and axial displacement measurement. This dual-sensor configuration enables engineers to capture both lateral and vertical movement within the same borehole system.

Because ground deformation is often multi-directional, the IPI-EX provides a more complete picture of subsurface behavior compared to traditional systems. As a result, it is particularly valuable for monitoring tailings dams, deep excavations, embankments, underground openings, landslides, and mining operations.

The instrument delivers continuous, automated data with high stability and long-term reliability. Furthermore, when integrated with real-time data acquisition units, the system supports threshold-based alerting, making it ideal for early-warning applications in critical geotechnical environments.
