VW Load Cell VWLC-5050

The VWLC 5050 series of Vibrating Wire Load Cells consist of a solid cylinder of high strength steel with 3 vibrating wire strain sensors mounted parallel to the longitudinal axis arranged equidistant around the circumference which measure the compression of the cylinder under load.



With the multi sensor configuration it is possible to obtain accurate readings under mildly eccentric loading conditions as the sensors are read individually.
The readings from the individual sensors are averaged and when used in conjunction with a calibration factor, supplied with each cell, allow the applied load to be calculated.
The VWLC 5050 series is typically used to measure and monitor compressive load or force in structural members, struts and piles.
Connection to the load cell is via a heavy-duty multi-core sheathed cable which can be connected to a direct portable readout, data logging or Wi-SOS 400 system.

Case Studies

Gardemobanen Venjar – Eidsvoll Rail Track

In 2018, NCC won a contract with Bane NOR to build a stretch of double track on the rail line from Venjar to north of Eidsvoll station in Akershus, Norway. The new double track is due to be operational by autumn 2022 and the contract work fully completed by summer 2023.
Around four kilometers of new double track will also be built north of Eidsvoll. In addition, there will be a 380m soft-ground tunnel, several rail bridges and culverts and rail engineering upgrades at Eidsvoll station. In total, over a million cubic meters of earth will have to be excavated from the site.
The project involved the following challenges:

  •  Extensive soft ground & clay deposits.
  •  Existing track operated as normal a few meters from the construction area.
  •  Important historic buildings (Eidsvoll church and rectory) close to the site.
  •  Important environmental and nature (wildlife and agricultural) area close by.
