The Model 4000 Rod Extensometer is a simple to install unit consisting of up to 6 spring steel rods anchored at measurement points within the borehole. As the anchors move the displacement variation is measured with respect to the instrument head. The measurement rods are sleeved in polyethylene tubing. ...
Manufactured by:Durham Geo Slope Indicator (DGSI) - part of Nova Metrix LLC based inTucker, GEORGIA (US) (USA)
The Rod Extensometer consists of anchors set at specified depths, rods inside protective tubing, and a reference head. Measurements are taken at the reference head by micrometer or by an electric sensor. Advantages: Can be automated, can be read remotely, works in any orientation, can measure multiple points. ...
Manufactured by:Soil Instruments Ltd - part of Nova Metrix LLC based inUckfield, UNITED KINGDOM
The Rod Extensometer system accurately measures settlement and/or heave at single or multiple anchor points in a borehole relative to it’s reference head. The system employs up to eight rods, anchored along the axis of a borehole with a diameter from 50mm up to 200mm, terminating in the reference head at the borehole entrance. The ...
