Vibrating Wire Load Cell

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

The Vibrating Wire Load Cell is designed to directly measure load in piles, rock bolts and between tunnel supports, as well as tension in cable 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.

The load cell can be wired directly to a data logger, or connected via sheathed cable and a switched terminal unit to a readout unit.

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.

Product Features:

• Uses proven Vibrating Wire technology
• Accurate readings over long cable lengths
• Robust and with long term stability
• Fast response time
• Suitable for remote reading and datalogging
• Negligible temperature effects compared to oil-filled load cells

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

Operation:

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 ITM Soil VWnote readout.
