Connect sensorized segments in the field for a continuous deformation profile.
SAAV Extend—our latest innovation addresses the challenges of continual deformation monitoring during the raising of tailings dams. Inspired by direct feedback from clients in the tailings and mine waste sectors, SAAV Extend provides a continual deformation profile throughout multiple dam raises with unparalleled ease of installation and data interpretation.
SAAV Extend is a modular ShapeArray™ system that scales along with your project’s scope. SAAV Extend includes a top assembly that connects to a base assembly that creates a continuous deformation profile of a borehole. When it is time to raise the tailings dam, SAAV Extend Lift Extension segments can be added between the top and base assemblies to increase the total sensorized length. SAAV Extend’s connectors are keyed to ensure azimuth is maintained as Lift Extension segments are added in the field.
SAAV Extend is designed for the field. Our toolless connectors ensure that SAAV Extend produces continuous and reliable, long-term data while submerged in water-logged environments.
SAAV Extend can be installed into existing casings, even those that are too distorted for conventional use, which eliminates the need to drill new boreholes when converting from manual to automated monitoring. SAAV’s patented cyclical installation method means it can be directly inserted into a range of casing sizes and widths, including both standard grooved inclinometer casings and smooth casing types, without assembly in the field. Measurand’s software tracks the medial axis in the centre of the casing in 3D to produce traditional inclinometer plots.
All ShapeArray instruments are manufactured in a high-capacity ISO 9001:2015 certified facility.
