Vibrating wire strain gauges are used to monitor strain in steel or in reinforced concrete and mass concrete structures. Arc-weldable vibrating wire strain-gauges are designed for arc welding to steel structures such as tunnel linings, piles and bridges. The gauge is supplied with end mounting blocks. Embedment vibrating wire strain-gauges are directly embedded in concrete for strain measurements of piles, foundations, dams, tunnels linings, etc.

Vibrating wire strain-gauges are particularly durable and thermally-aged to minimize long-term drift and changes calibration. Thermistor is incorporated in the soil housing. The standard gauge length is 150mm with a nominal range of 3000µƐ.
