Borehole Rod Extensometers
Design & Operation
The Rod Extensometer is isolated from the backfill material by a protective sleeve that ensures free movement. Displacement along the borehole axis from the anchor is recorded by measuring movement of the top of the rod relative to the reference head.
Product Features
Supplied in component form for on-site assembly with Stainless Steel or fibreglass rods and multiple anchor configurations.
Product Benefits
Suitable for installation at any orientation with manual or remote monitoring and adaptable rod lengths exceeding 100m.
Options
Configurable with automatic or manual reading, hydraulic or groutable anchors, and single or multiple point references.
Remote Monitoring
Remote monitoring options include Vibrating Wire and potentiometric displacement transducers with data logging compatibility.
Flexible Installation
Designed for borehole diameters up to 200mm with support for up to 8 anchors installed at different depths.
Operation
Measures relative movement using dial depth gauges or displacement transducers depending on project requirements.
Borehole Rod Extensometer Operation
Groutable anchors are suitable for rock installations, hydraulic anchors for soft soils, and packer anchors for jointed rock or flowing water conditions. Reference heads support up to eight measuring points per borehole.
