Designed primarily to measure strains on the surface of steel structures.

Consists of two end blocks with a tensioned steel wire between. As the surface undergoes strain the blocks move changing tension in the wire. A VW readout generates voltage pulses and measures the resonant frequency of vibration.

Available in two versions:

Gauge with integral coil housing
Gauge only with separate coil housing

Applications:

Struts and support systems
Pipelines
Bridges & Dams; Buildings
Tunnel linings
Piles & Mass Concrete
