TECNOPENTA MEASURING GEOTECNICA CEOLOGIA IDROGEOLOGIA METEOROLOGIA Rigid bar extensometers allow for the monitoring of rock or soil movement caused by sliding, fracturing, or settling through precise displacement measurements. They consist of a rigid rod, which is inserted into a borehole and used to measure the relative displacements occurring between the anchoring point and the surface. The measuring head, located at the surface, can support multiple rigid rods of different lengths. These rods have bottom anchors that terminate at different depths, allowing the detection of differential displacements between soil or rock layers. TECNOPENTA S.r.l. Via G. Galilei, 7A/2 35037 TEOLO (PD) The measuring bases are enclosed in protective tubes with an internal diameter slightly larger than the external diameter of the bases. This allows the bases to slide with minimal friction, helping to prevent bar bending caused by gravitational forces.

TECNOPENTA Stainless Steel Bar Measuring Base: The measuring base consists of stainless steel rods measuring 2 or 3 meters in length, which are joined together during borehole installation using stainless steel threaded couplings. The protective casing, typically made of PVC, is composed of 2-3 meter sections, either threaded or fitted with sleeves that allow the segments to be connected. The PVC provides an effective seal against water and grout, which is injected into the bottom part of the borehole upon completion of the extensometer installation. Bar extensometers are preferable to wire extensometers...
