Strain gauges are used to determine deformations caused by compressive or tensile stresses on steel construction elements or on/in concrete construction elements. We exclusively use sensors by the worldwide renowned manufacturer Geokon with Vibrating Wire (VW) technology for these applications. As shotcrete can absorb larger deformations than concrete, transducers with a measuring range of 10,000 µε are available. VW sensors are characterized by their long-term stability and loss-free signal transmission, even with long cable lengths. Depending on the application, a large number of different types can be selected for installation in concrete or shotcrete, for dribbling instrumentation or for assembly on concrete or steel components.
Pressure load cells are used to determine the stress within concrete or shotcrete elements, dams and embankments or at the contact surfaces between an embankment and the ground or the shotcrete lining and the rock. The data obtained this way provide information about the stress state within individual components or the forces prevailing at the contact surfaces between the different materials. We offer transducers with conventional pressure sensors or with VW technology. If there is a potential danger of falsification of the measured value due to shrinkage of the concrete, a version with a retensioning device can be selected. We will be happy to help you select a suitable sensor type.
