Vertical Digital Inclinometer System Overview
|
The Geomotion Digital Bluetooth Biaxial Vertical Inclinometer System has been specially developed for monitoring lateral movements and deformations of soil, rock including retaining structures.
The Vertical Digital Inclinometer System comprises a biaxial probe, cable reel and a rugged field PC supplied with ‘Inport’ data logging software. The Digital Inclinometer System takes highly accurate readings of lateral deflections. A Bluetooth connection between the instrument and the field PC makes taking readings fast, simple and allows for winding of the cable reel as you take readings without having to disconnect datalogging equipment. The Kevlar reinforced cable provides strength but yields significant weight reductions. |

Operation |
The inclinometer probe is inserted into the inclinometer casing and lowered to depth, ensuring the probe wheels are correctly aligned and slotted within the keyways of the casing. The probe is connected by a graduated cable to the cable reel.
Displacement readings are taken at regular intervals of 0.5m within the casing (the gauge length between the probe wheels). This is measured and controlled by metal markers crimped around the cable that pass through a notch in the cable gate, giving an exact position for each reading. A ‘key fob’ activates the saving of readings from the MEMS sensors, which are transmitted to the field PC from the cable reel via Bluetooth transmission and saved. An initial or ‘base’ set of inclinometer readings are obtained at each increment within the casing. The summation of each incremental reading provides a profile of horizontal displacement of the casing as a function of depth. When you take all subsequent readings at identical depths the comparison of successive casing profiles indicates the depth, direction, magnitude and the rate of change of movement. You can see the clearest indication of movement by plotting the change in displacement of the casing against depth using ‘In-Site’ Inclinometer Data Management Package. |
Application |
Inclinometer systems measure lateral movement in the ground or in a structure. They are useful for determining the depth, direction, magnitude, and also rate of movement.
For example, they can be used to ascertain the stability of retaining walls by measuring bending and rotation in the retaining wall. They can also reveal ground movement that could affect other buildings. Inclinometer systems can be used to detect and monitor deformation of upstream slabs of concrete-faced rock-fill dams, to monitor the up and downstream displacements of embankment and concrete dams and to define and monitor shear zones in the foundations of all dams. The measurements of recorded movement can be utlised to check that the deflections are within the design assumptions. Continue monitoring to establish any long term effects after works have finished. Use inclinometer casing in boreholes, embedded in fill material, cast into concrete or attached to structures for the following typical applications:
