Gage Technique Accoustic Gauge Strain Meter GT1169

Acoustic strain gauge :
In an acoustic strain gauge the variation in length of a wire stretched between two gauge points is measured which alters the natural frequency of the wire.
The magnitude of frequency change for a strain gauge can be increased by decreasing the length of the wire or stress in wire.These gauges are highly accurate and long term reliable. Optical strain gauges are used to measure strains in concrete structure, concrete dams, rock, steel structures etc.
