Convergence extensometer
<p>Convergence Extensometers allow to monitor the changes in the distance between two anchor points.<br>Typical applications include convergence monitoring in tunnels, caverns, underground mining and structural health monitoring. <br>The convergence Extensometer ...
DBS Measuring Anchors
<p>Sisgeo measuring anchors are designed as an instrumented rockbolt; they are composed by four iron rods anchored every 1/4 of the grouted instrument length, a 38mm OD tube and a measuring head.<br />Replacement of typical working anchors with measuring anchors ...
Embankment Extensometers
<p>Embankment extensometers are used to measure soil strains in large earth structures. Embankment extensometers are usually incorporated in the filling material, chained together by means of extension rod.<br>The system consists of several measuring units ...
ERI Fill Extensometer
<p>The ERI is a fill extensometer designed to monitor longitudinal displacements between two points inside any type of man-made fill. It is usually installed horizontally in trenches. It may also be installed vertically to measure settlement at the point of ...
Fixed Extensometers
<p>Fixed extensometer is usually defined as device placed in embankment fill or inside borehole for monitoring of settlement or heave between two points without use of a removable probe.<br>Either the Settlement Platform and the Tell-Tale extensometer are ...
MEXID Miniaturized MPBX
<p>MEXID extensometers are used to monitor displacements of measuring points deeply positioned in grounds or rocks, with reference to the instrument head.<br>The main strength of MEXID is the small drilling diameter: only 50mm (75mm first meter only).<br>MEXID ...
Multiple Point, Retrievable-Model 1300 (A-9)
<p>The Model A-9 Retrievable Extensometer (Patent No. 5,585,555) is designed to measure deformations in boreholes in rock, concrete, and other construction materials. The device can be used in pile load test studies, plate jacking tests and virtually any application ...
Single Point, Rod, Mechanical-Model 1050 (A-1)
<p>The Model A-1 Single Position Rod Extensometer is a very simple, rugged and reliable instrument, easily installed and completely recessed within the borehole for optimum protection. The Model A-1 is a natural first choice for monitoring the safety in and ...
SMART Cable Bolt
<p>By combining the support capabilities of a standard 7-strand cable bolt with a miniature 6-wire extensometer, the SMART (Stretch Measurement to Assess Reinforcement Tension) Cable was born.<br />The stretch in the cable is determined via the integrated ...
SMART Cable-SP
<p>Built on our industry standard SMART Cable technology, the SMART Cable- SP has a completely redesigned head to allow it to be spun into the borehole, rather than grouted using standard practices. More mines are using Maclean bolters to install cable bolts ...
