Vibrating Wire Strain Gauges(Surface)
Type VWS-SM vibrating wire surface strain gauge is mainly used for strain monitoring of bridges, highways, railways, subways,tunnels, pile foundations and other structures. It can be welded on the surface of steel structures or bolted on the surface of various structures for long-term automatic monitoring and regular detection. The built-in temperature sensor of the strain gauge can monitor the ambient temperature at the same time. Advantages of vibrating wire strain gages are that the frequency output is immune to electrical noise, is tolerant of wet wiring commonly found in geotechnical applications,and can transmit signals over many kilometers without loss of signal.
