Strain Gauge Model SS-2405 basically consists of a steel wire tensioned inside a stainless-steel tube between two mounting blocks with groutable anchor embedded into concrete. The relative movement between the two mounting blocks causing a change in the steel wire tension and a corresponding change in its frequency of vibration produces the deformation of the structure under load. The tension in the wire is measured by plucking the wire using an electromagnetic coil connected through a signal cable to a readout, which also measures the resonant frequency and display the strain in the wire directly in microstrain.
