The Enviko SK-GD general-purpose vibrating wire strain gauge monitors stress and strain in beams, piles and pile foundations, supports, hydraulic structures, linings, piers and bedrock of concrete structures. It is also used for strain monitoring of steel structures, steel plates and bridges. A built-in temperature sensor records ambient temperature.
