Inclined Digital Inclinometer System Overview

The Geomotion Digital Bluetooth Uniaxial Inclined Inclinometer System has been specially developed for monitoring lateral movements and deformations of soil, rock including retaining structures.

The Inclined Digital Inclinometer System is used to manually monitor lateral deformations within an inclined borehole.

The system comprises a uniaxial probe, cable reel and a rugged Field PC supplied with ‘In-Port’ data logging software.

The probe, fitted with spring loaded guide wheels, is inserted into specially installed inclinometer casing which is either embedded in fill or secured to the structure to be monitored. A Kevlar reinforced graduated cable connects the probe to the cable reel and hub.

Readings are transmitted quickly and efficiently to a rugged Field PC via a Bluetooth link.

Operation
The inclinometer probe is inserted into inclinometer casing in 0.5metre increments. This is measured by metal markers crimped around the cable (also at 0.5m increments) and controlled by a notch in the cable gate. This ensures accurate and repeatable data when taking multiple readings.

Each increment of data is read by means of a key fob. The key fob is activated by the user to transmit instructions for the data to be read by the probe; the data is then sent to the hub and transmitted via Bluetooth to the Field PC which saves the data using itmsoil ‘In-Port’ software.

An initial or base set of readings are obtained at each increment determined by the casing position. Subsequent readings are taken at identical positions; the comparison of all subsequent readings indicates the location, direction, magnitude and rate of change of movement.

The data can be saved to the Field PC SD card in RPP format. Using a Windows PC, the data can be further analysed using itmsoil ‘In-Site’ software.

Application
Inclined Inclinometer Systems can be used to provide settlement profiles and monitoring of heave in projects such as:
  • Embankments
  • Dams, particularly monitoring downstream faces of concrete-faced rockfill dams
  • Structures
