Web1 x BOSCH GIM 120 Inclinometer. Measurement range. 0 – 360° (4 x 90°) Length. 120 cm. Electronics measurement accuracy 0°/90°. ± 0.05°. Electronics measuring accuracy at 1– 89°. ± 0.2°. WebSlope inclinometers are geotechnical instruments used to measure horizontal displacements along various points on a borehole. For this reason, sometimes they are also called borehole inclinometers or simply inclinometers. Slope inclinometers are the most important source of geotechnical data during construction (Erikson et. al., 1992).
How to Install Digital Inclinometer in a Borehole? Borehole Drilling Start by drilling a 125mm hole around 0.5m more than the planned depth of the inclinometer casing. (Try keeping the hole as vertical as possible) The diameter of the drill hole should facilitate grouting around outside of the casing. See more Casings must be grouted as directed by project authorities. Ideally, grout should be mixed to match the strength and deformation characteristics of material around the borehole. … See more Check installed access tubing by dummy probe (EAN-26) for smooth movement up to the bottom of the borehole. Figure 3: Checking Inclinometer … See more Mark casing grooves as ‘A+’, ’B+’, ’A-’, and ‘B-’ with a permanent ink marker pen. If the uppermost probe wheel is pointed in direction of major principle plane of movement, casing groove pointing in this direction is marked as … See more WebInclinometer Casing is suited to be installed in boreholes, piles, set into concrete or attached to structures. The casing serves as an access tube to guide a servo accelerometer based probe in the two orthogonal directions of measurement. …
