The Vibrating Wire Embedment Strain Gauge is used for measuring strain in mass concrete. The 150mm long gauge, which is made from stainless steel, may be pre-attached to rebar or by attachment to a 2, 3 or 4 directional rosette, thereby measuring strain in several directions. The gauge comprises a sealed tube containing a wire held in tension between two circular stainless steel pads, one at each end. Deformation to these pads alters the tension of the wire and the resulting readings are used to measure strain. The changes in strain are monitored by the coil assembly mounted on the gauge. The gauges can also read temperature if required. The gauges can be read individually or remotely/automatically as part of a data collection system.
