Solexperts - Reverse Head / Chain Extensometer - Brochure

With the Reverse Head Extensometer, deformations can be continuously observed during excavation in front of the tunnel face or during the removal of slopes or the excavation of excavation pits. The modular design based on a chain of single extensometers provides a large number of measuring points in small diameter boreholes. The big advantage compared to other extrusion measuring systems is the continuous measurement of deformations during tunnelling or excavation. The manual readout of the stored measurements is done in a few minutes with a portable PC or PDA. The recording rate for the measured values of the individual displacement transducers is freely selectable.
