The Enviko SK-CS vibrating wire surface strain gauge measures stress and strain on the surface of concrete structures over the long term. It consists of a sensor, strain body, protective sleeve and mounting base, and its built-in temperature sensor records ambient temperature for temperature compensation. A smart chip can be added on request.
