CGEO-LC Vibrating Wire Load Cell

Description

CGEO-LC Vibrating Wire Load Cell is designed for monitoring the loads on anchor cables, anchor bolts, rock bolts, and arch supports, as well as other heavy loads. The load cell is made of high-strength alloy steel cylinder and is equipped with 3 to 6 vibrating wire sensors that can monitor the total load acting on the load cell. By measuring the data from each sensor, uneven or eccentric loads can be obtained.

Applications

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

Operation

The Model CGEO-LC Load Cell is designed primarily for use on tiebacks and rockbolts and particularly where long term monitoring is required. They may also be used during pile load tests and for monitoring loads in struts, tunnel supports, etc. In practically all cases, the load cells are used in conjunction with bearing plates positioned on either side of the load 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. To minimize eccentric and uneven loading, the use of the 

thick machined-flat bearing plates and centralizer bushings (where necessary) are recommended.

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 CGEO-HH-VW readout. Alternatively, cells can be wired to a datalogger.
