Magnet extensometer (BRS)


Magnet extensometer is a system, based on British Building Research techniques, for either settlement or heave at various depths in soil, embankments, earthfill dams and dikes.
The system consists of an access tube with external corrugate pipe, magnet rings, as well as a telescopic bottom section with datum ring and suspension head. Magnet rings (targets) are positioned externally to the access tube, and then placed in the ground where movements may occur. Magnet rings move together with surrounding soil along the axis of the access tube.
Readings are obtained with a portable unit linked to the reed switch that is lowered down the access tube. Comparison of data taken, over time provides profiles of ground settlement or heave.
