Vibrating Wire Settlement Cell

Vibrating Wire Settlement Cell Overview

The Vibrating Wire Settlement Cell is used for the measurement & control of settlement in soil at a single point.

The Vibrating Wire Settlement Cell measures settlement and heave in soil and rockfill. Using measurement data from the settlement cell can help to control further displacement.

The cell consists of a Vibrating Wire pressure transducer connected via a pair of water-filled nylon tubes to a hydraulic datum pot located on stable ground.

Vertical movement of the cell relative to its readout location results in a change in liquid pressure within the chamber, which is recorded in metres of water and is translated into the amount of settlement or heave.

The Vibrating Wire Settlement Cell can take measurements beneath concrete and earth structures at locations that are inaccessible to other types of instruments.

Product Features

  • Uses proven Vibrating Wire technology
  • 15m and 30m ranges available
  • Borehole, trench and low profile types available
  • No vertical rods or tubes to interfere with construction
  • Twin liquid lines allow for recirculation of water through the system after installation
  • Does not require access above sensor to acquire data

Product Benefits

  • Over 30 years of expertise in the design and manufacture of Vibrating Wire instrument technology
  • Accurate, repeatable readings over long cable lengths
  • Long working life, longterm stability and reliability
  • Over-voltage surge arrestor protects against electrical damage
  • Connecting cable is strong, armoured and flexible
  • Measurements unaffected by lateral movements

Operation

The cell is installed in a borehole or trench. Vertical displacement of the cell relative to the datum location results in a liquid pressure change at the transducer.

To measure the pressure change and hence the amount of displacement, a Vibrating Wire readout or data logger provides a direct reading of fluid pressure acting on the cell. The pressure is displayed in metres of water and can be recorded for comparison with previously recorded data.

Application

The Settlement Cell is used for monitoring settlement in soil and rockfill.

Typical monitoring applications include:
  • Measuring vertical displacement beneath and within embankments, earth and rockfill dams
  • Measuring vertical displacement of oil tanks and building foundations
  • Subsidence

Technical Rating

As the correct installation of any monitoring sensor or system is vital to maximise performance and accuracy, Geomotion makes the following recommendations for the skill level of the installation contractor.

Technical Rating for this Product:  BASIC

As a minimum the installer has read and fully comprehends the manual, and if possible has observed these instruments or systems being installed by others.

Geomotion offer installation and monitoring services to support this system. For more information please contact us.
