<p>The Geosense® In-Place Inclinometer System (IPI) measures tilt and is used to calculate rotation and/or displacement in a vertical, inclined, or horizontal orientation. It is available in either a Uniaxial or Biaxial version.</p><p>The system consists of ...
<p>The Vibrating Wire Liquid Settlement System model SSVW105 is developed to monitor settlement or heave in soils and different types of man made structures such as embankments, and earth and rockfil dams. The system consists of a fluid body, reservoir, flexible ...
<p>The NIVOLIC SG is a high-precision liquid level system designed to measure relative settlement in a multipoint system. It consists of a series of chambers connected together by a liquid line. In each chamber, a weight is suspended to a vibrating wire transducer.</p><div ...
<p>Wire deformometers allows to monitor the changes in the distance between two anchor points.<br>Typical applications include measurements of small cracks, convergence monitoring in tunnel and structural deformations.<br>The USB wire deformometer consist ...
<p>In late 2009 the U.S. Geological Survey (USGS) and National Park Service (NPS) joined into a collaborative research project to investigate the deformation of large, vertically-oriented, granite slabs in response to thermal heating and solar radiation. The ...
<p>The Model 4415 3-Dimensional Crackmeter is a simple and rugged instrument designed to manually measure the displacement across cracks and/or expansion joints in three directions.<br><br>Mechanical Range 0-12.5 mm, in each X, Y, Z axis <br>Distance Between ...
<p>The 3DeMoN laser is an optical system that measures the flight time of a Class II visible red laser light beam, thus precisely calculating the distance between the module and any kind of surface.</p><p>For distances above 50 – 65m, the use of a reflective ...
<p>Analog Extensometer is a sensor of electric current output type to measure displacement on the ground surface. The displacement is measured by change of the wire length between two (2) points that one is at a fixed site and another is at a moving area. ...
<p>Borros Type Hydraulic Anchor: For use in soft soils and clays, especially in augered boreholes. Can also be driven directly through soft ground without a borehole being required (please see the Model 1950 data sheet).<br /><br />Groutable Anchor: The preferred ...
The BCS monitors movement of reference points that are mounted on the tunnel lining. The points are aligned to a plane that is normal to the axis of the tunnel. A system of articulated arms links each reference point to the next, and forms a series of virtual ...
