The Enviko SK-SP vibrating wire steel plate strain gauge monitors strain on steel structures such as pipelines, steel frames, steel sheet piles and bridges. It is fixed to the steel with welded mounting bases and measures strain as the stress in the steel changes. A built-in temperature sensor records ambient temperature, and a smart chip can be added on request.
