BOR-EX - Rod-Type Borehole Extensometer
<p>The BOR-EX allows for measurements of precise longitudinal dis-placements in rock, soil and concrete structures. Typically it is used for monitoring settlement in foundations, subsidence above tunnels, displacements of retaining structures, and deformations ...
Continuous Rod Extensometer
<p>The Continuous Rod Extensometer system accurately measures settlement and/or heave at single or multiple anchor points in a borehole and at its reference head. The system employs up to eight rods, anchored along the axis of a borehole, terminating in the ...
Flexible Rod Extensometer EXB0005F
<p>A low cost, convenient instrument for the monitoring of ground displacements. Designed to withstand severe field conditions and accommodate transverse shear. The unit is supplied completely assembled and sealed for grouting into the borehole. Rod displacement ...
Flexible Rod Extensometers - Model A6
<p>The Model A-6 Flexible Rod Extensometer uses continuous lengths of fiberglass rods (inside protective tubing), cut to customer-specified lengths, coiled at the factory and shipped ready for installation. The extensometer is lightweight, making it easier ...
Geosense Borehole Rod Extensometer
<p>The Geosense® GEO-XB2 borehole rod type extensometer range is used to measure and locate settlement, displacement and deformation in soil and rock.<br> <br>It consists of a reference head and one or more in-hole anchors each of which is placed at a known ...
INCREX
<p>INCREX consists of a mobile extensometer probe cabled to a readout unit via a cable reel. The probe is fitted with two high precision induction coils at its ends set at one metre apart. Special metal rings are fitted to the outside of the ABS inclinometer ...
MPBX Multipoint Borehole Extensometers
<p>Rod extensometers are installed in borehole to monitor displacements at various depths using rods of different material and lengths. A pre-set length of measuring rod is inserted into a nylon tube to avoid soil friction and its tip is fixed to a steel groutable ...
Multiple Point Rod Extensometers - Model A3
<p>The Model A-3 Multiple Point Rod Extensometer is the preferred design for installation in downward directed boreholes which are easily filled with cement grout. Up to eight anchors can be installed, at various depths, in a 76 mm diameter borehole providing ...
Multiple Point Rod Extensometers, Hydraulic Anchor - Model A5
<p>The Model A-5 Multiple Point Rod Extensometer with Hydraulic Anchors is recommended for use in soft ground and soils or in rock where the borehole may deteriorate. This anchor is very versatile and can be used in boreholes of varying diameter and roughness ...
Multiple Point Rod Extensometers, Snap-Ring Anchor - Model A4
<p>The Model A-4 Multiple Point Rod Extensometer with Snap-Ring Anchors is quickly and easily installed in boreholes in hard or competent rock. Anchors are pushed to the required depth on the end of setting rods and then a cord is pulled to remove the locking ...
