Essential tools for empirical structural verification, they allow for comprehensive tension control, collapse prevention, and design optimization in engineering projects. Their use is imperative in monitoring post-tensioned anchors, rock bolts, steel struts, deep excavations, pile testing, and tunnels.
They are available in various technical configurations: resistive cells with ultra-rigid distribution plates, annular plates filled with de-aired oil for hydraulic measurement, compact blocks, and vibrating wire cylinders in a solid structure. Additionally, they include clamping devices to measure pure tensile stress and transducers designed to capture dynamic events and sudden load peaks, managed via multi-channel dataloggers.
