Digital Tape Extensometer
<p>Stainless steel reference points are permanently installed at measurement stations along the tunnel or structure. To obtain a measurement, the operator stretches the tape between two reference points, hooking the free end of the tape to one point and the ...
EL Tiltmeters
<p>EL tiltmeters are narrow-angle, high-resolution sensors used to monitor changes in the inclination of a structure. They can provide an accurate history of movement and early warning of potential structural damage. An EL tiltmeter consists of an electrolytic ...
Goodman Jack
<p>The Goodman Jack is a borehole tool used for estimating the deformability of rock masses in-situ. It is designed to be used in 3"" (76 mm) boreholes. The Goodman Jack consists of a hydraulic jack with curved bearing plates, LVDT sensors, a displacement ...
Inclinometer Casing
<p>Inclinometer casing is a special purpose pipe used in inclinometer installations. It performs three functions: a) It maintains access for the inclinometer probe, allowing it to obtain subsurface measurements. b) It controls the orientation of the probe ...
Magnet Extensometer
<p>The magnet extensometer is used to monitor settlement and heave in excavations, foundations, dams, and embankments. It can also be installed behind retaining structures, such as sheet piles and slurry walls, and above underground openings, such as tunnels ...
Multi-Level VW Piezometer
<p>Multi-Level VW Piezometers are used to monitor pore-water pressure at different zones in the borehole. The multi-level system consists of VW piezometers in multi-level housings, as shown in the photograph at right, and PVC placement pipe. The piezometers ...
Pneumatic Piezometer
<p>Pneumatic piezometers are used to measure pore water pressure in saturated soils. Applications include: Monitoring pore pressures to determine safe rates of fill or excavation. Monitoring pore water pressures to determine slope stability. Monitoring the ...
Rod Extensometer
<p>The rod extensometer monitors changes in the distance between one or more downhole anchors and a reference head at the borehole collar. Components of a rod extensometer include anchors, rods with protective tubing, and a reference head. The anchors, with ...
Soil Strainmeter
<p>The soil strainmeter employs a potentiometer and a rod mounted between two anchors to monitor horizontal movements of the surrounding soil. These components are linked together so that movement of one anchor relative to the other causes a change in the ...
Sondex Settlement System
<p>The Sondex Settlement System is used to monitor settlement and heave in excavations, foundations, dams, and embankments. It can also be installed behind retaining structures, such as sheet piles and slurry walls, and above underground openings, such as ...
