BSIL - Model BSIL-ST2/ST2X/ST3 VW -Surface Mount Strain Gauge
The Vibrating Wire Strain Gauge measures strain in steel members. The gauge consists of a coil assembly, Vibrating Wire element and two weldable anchors.The strain gauge incorporates O-ring seals to provide waterproofing, and allows the tube to remain unstressed. A factory fitted, four core screened cable connects the coil to the readout unit.

- 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.
