Operation
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.
CGEO-SG2 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.
