Inclinometers measure underground lateral displacements within soil and rock. Adequate ground support is essential for almost any major construction, whether it be a dam, retaining wall, pit mine, or other load-bearing structure. Careful monitoring of ground stability is necessary both during construction and as an ongoing measure to ensure the safety and long-term stability of the structure.
RST Instruments’ various inclinometer tools allow for lateral ground displacement monitoring in a variety of geotechnical applications. Displacement measurements from inclinometers can be used to determine the stability of a slope, the rate of ground creep, or shear zone movement, and allow assessment of the adequacy of ground supports before embarking on a major construction project.
The RST Digital Inclinometer System consists of a lightweight digital inclinometer probe at the end of a heavy-duty cable that is read with an Ultra-Rugged Field PC Data Logger allowing to visualize inclinometer profiles on site.
Inclinometer casings can be installed vertically in boreholes, embankments, and piles, and can be set into concrete or attached to structures, allowing for repeated measurements over time using the digital inclinometer probe. As the probe moves vertically through the casing, it measures lateral displacement against a reference value taken at the initial installation, thereby providing a detailed view of any and all lateral displacement that has occurred beneath the ground surface over time.
For projects where ongoing or remote monitoring is required, the next-generation MEMS Digital In-Place MEMS Inclinometer System is a long-term installation available in four different configurations to accommodate the specific needs of your project within the installation environment. MEMS Digital In-Place Inclinometer Systems are typically used to monitor embankments and landslide areas and are read automatically with the DT2485 RSTAR Data Logger node.
The Digital Horizontal Inclinometer System can be used to measure ground settlement under structures or embankments in much the same way by running the Digital Horizontal Inclinometer probe through an inclinometer casing that has been installed horizontally beneath the ground surface.
