The measurement of displacement vectors along measurement lines (boreholes) provides information about the deformation behaviour of hard rock and unconsolidated rock in the area of the monitored terrain or structure and about the interaction between the structure and the ground.

With the Trivec, displacement and deformation profiles in soil, rock or structures are precisely recorded metre by metre along vertical measurement lines. The measuring accuracy in horizontal direction ΔX and ΔY is +/-0.04 mm/m and in vertical direction ΔZ +/-0.002 mm/m. The measuring range is +/-10 mm/m in Z and +/- 10° in X and Y from the vertical line.
