Deformation of the structure under load produces relative movement between the two mounting blocks causing a change in the wire tension and a corresponding change in its frequency of vibration. Once installed, changes in strain are monitored by the coil assembly mounted on the gauge. The gauges can be read individually or remotely/automatically as part of a data collection system.
BSIL-ST2 Vibrating Wire Arc Weldable Strain Gauge basically consists of a length of steel wire tensioned between two
mounting blocks that are arc welded to the surface of a structural steel member.
BSIL-S2X Vibrating Wire Arc Weldable Strain Gauge is designed as a one-piece structure for measuring strains in steel members and incorporate the excellent waterproof performance (can be customized) and techniques to allow these gauges to work in hostile conditions.
BSIL-ST3 Vibrating Wire Strain Gauge contains two groutable anchors to be embed the unit in the materials such as wood, rock or concrete.
