VW SOIL EXTENSOMETER
The GEO-XS VW Soil Extensometer monitors lateral and longitudinal deformation of soil and different types of embankments and embankment dams.
It comprises a displacement transducer connected to an extension rod and fixed between a pair of anchor beams.
Description
The assembly is housed in and protected by an external telescopic sleeve. To form a ‘Chain Extensometer’, Soil Extensometers are linked together, in series, using the anchor beams as connectors.
The internal sensing element is housed within an outer PVC sleeve which is sealed by O-rings at each end. The sleeve, with telescopic sections with O- ring seals, is extended along the whole length of the rod to the next anchor.
As structural movement occurs, the rod is moved within the housing. The shaft movement changes the tension in the sensor spring which, in turn, changes the tension in the Vibrating Wire.
Different combinations of anchor spacing (Gauge Length) and sensor range can we used to provide an optimum sensing accuracy and range. i.e. for maximum strain resolution, a shorter transducer length will provide the best results. For maximum deformation, use a longer transducer or a shorter gauge length.

MEMS Tilt Beams are designed for attachment to structures, on either a vertical or horizontal surface, for the measurement of tilt or differential settlement.
They consist of a highly accurate MEMS sensor housed in a fully sealed enclosure which is mounted on a lightweight rigid GRP beam. This can be mounted onto the structure using special anchors. The GRP beam has a very low coefficient of thermal expansion meaning that thermal affects are minimised.
PENDULUM SYSTEM
In stock
HPS-3500 (Hanging) and IPS-3000 (Inverted) Pendulums are used to measure the tilt or rotation by measuring the relative internal horizontal displacement of points along a true vertical line. Each has a tensioned, stainless steel wire and the effects of the earth gravitational forces to guarantee a perfectly vertical line between a fixed point and a tensioning mechanism. Typical applications include concrete dams, bridges and high rise buildings.

The GEO-XM settlement system is a magnet extensometer system used typically to monitor settlement and heave in foundations, excavations and embankments.
Data received identifies the depth and position where settlement has occurred as well as the total amount of settlement.
It can also be installed behind retaining structures, such as sheet piles and slurry walls, and above underground openings, such as tunnels and shafts.
