VWS type vibrating wire strain gaugeDetailed product description：

The VWS type vibrating wire strain gauge is suitable for long-term burial in hydraulic concrete structures or other concrete structures, measuring the internal strain of the structure and synchronously measuring the temperature at the burial point. Installing supporting accessories can form instruments for measuring strain, such as multi-directional strain gauges, stress gauges, and rock strain gauges.
