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 centre hole to accommodate anchors, rock bolts and tendons. 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.
