VW ANCHOR LOAD CELLS VWLC-5000
The VWLC 5000 series Vibrating Wire Anchor Load Cells consist of a cylinder of high strength steel with 3 to 6 vibrating wire strain sensors (depending on capacity) mounted parallel to the longitudinal axis arranged equidistant around the circumference which measure the compression of the cylinder under load.
They are manufactured with a Center hole to accommodate anchors, rock bolts and tendons.
Description
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.
In multi-strand anchors it is therefore possible to tension the strands uniformly by monitoring the load in each sensor as appropriate.
The abutment plate (provided locally) is normally made to suit specific site requirements and load distribution plate pairs (supplied by Geosense) should be used to minimise eccentric loading and provide a smooth parallel bearing surface and evenly spread the load to the cell. These should be inserted between the load cell and the anchor head.

IPX IN-PLACE EXTENSOMETER
In stock
The In-Place Extensometer (IPX) offers automated monitoring of standard magnetic extensometer installations. The system is designed for a simple, adaptable installation with a single cable connection at the top of the borehole. Its large measurement range accommodates large levels of settlement or heave, and ease of adjustment means it can be reconfigured for changed site conditions such as embankment filling or cutting.
