MEXID Miniaturized MPBX
The MEXID Miniaturized MPBX is a small-diameter Multi-Point Borehole Extensometer (MPBX) designed for 50mm (2") boreholes. The MEXID is ready to monitor up to four points. The system incorporates steel anchors, fiberglass rods, dedicated grouting tubes, and vibrating wire or 4-20mA
displacement transducers. The stainless steel extensometer head installs flush with the surface, minimizing any obstruction of the work area.
