The Enviko SK-SD vibrating wire surface strain gauge monitors strain on pipelines, steel structures, steel plates and bridges. Its two end blocks can be arc-welded or bolted to a steel surface. On concrete, the gauge is fixed with short anchor bars set in drilled holes. A built-in temperature sensor records ambient temperature.
