Particularly suitable for the long-term monitoring of concrete structures.
Consists of two end flanges with a tensioned steel wire between them. As concrete undergoes strain, the end blocks will move and the tension in the wire changes. A vibrating wire readout generates voltage pulses in the magnet/coil at the centre of the gauge and measures the resonant frequency of vibration.
