Vibrating Wire Load Cells

The Vibrating Wire Load Cells are ideally suited for measuring loads in rock bolts, cable anchors and tendons, structural beams, piles, loads between tunnel supports, and loads in pull-out tests on trial anchors.

The load cell comprises a set of up to six Vibrating Wire gauges mounted parallel to the cell axis and spaced equidistant radially in a cylindrical housing. It can be wired directly to a data logger, or connected via a sheathed cable and a switched terminal unit to a readout unit.

Vibrating wire load cells are manufactured with a centre hole to accommodate rock bolts, tendons, or anchor cables, but can be supplied with top and bottom load plates for use as a solid centre cell.

A bearing plate is placed beneath the Load Cell to spread the load and take up any residual non alignment. Another bearing plate is placed between the cell and the anchor bolt or tensioning device.

The readings from up to six gauges are averaged to produce the total load for the cell.

Calibration factors are provided to enable direct reading in engineering units when using itmsoil VWnote readout. Alternatively, cells can be wired to a datalogger.


Vibrating Wire Load Cells can be used to measure general or specific loads.

Typical applications include:
  • Rock bolts
  • Tensions in cable anchors and tendons
  • Structural beams
  • Piles
  • Tunnel supports
  • Loading and pull-out tests on trial anchors
  • Loads during pile testing
  • Loads in arch tunnel supports
  • Long term loads in concrete dams
