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 reference head at the borehole entrance. Displacement along the axis of the borehole from the anchor is recorded by measuring movement of the top of the rod relative to the reference head. The Continous Rod Extensometer is pre-assembled to specified lengths. A versatile range of options are available for Continuous Rod Extensometers:
- Automatic or manual reading
- Hydraulic anchoring for soil
- Groutable anchoring for rock
- Multiple or single point rod reference
