Shape Accel Arrays GS-SAA02 Array Displacement Meter

The GS-SAA02 Array Displacement Meter delivers high-precision real-time displacement monitoring for hydraulic structures, slopes, and foundations. Featuring advanced MEMS technology, temperature compensation, and torsional correction, it provides reliable long-term performance in demanding environments.

A flexible segmented modular construction allows onsite length configuration and reuse across multiple projects, with section options of 0.3 m, 0.5 m, or 1 m and customisable total sensor length. 200 m underwater (2 MPa) waterproofing and a −40 °C to 60 °C operating envelope suit harsh installations including dams, deep boreholes, and tunnels.
