ShapeArray that grows with your monitoring strategy
SAAV Extend will always have a sensorized length that is right for your needs. Individual sensor segments are 500 mm each, and can be combined up to a total sensorized length of 200 m.
Simple installation in the field
SAAV Extend's hand-tight threaded connectors allow clients to easily add sections of lift extension segments without additional tools. Adding new lift extension segments is as simple as twisting, while keyed alignment marks on the connectors maintain the ShapeArray’s azimuth.
Durable, connectable design
Designed specifically for the rigors of tailings dam safety monitoring, SAAV Extend is submersible up to a depth of 200 m. SAAV Extend has the same 38-year MTTF as any ShapeArray that Measurand manufactures. It also has the same temperature tolerances and tensile strength, so clients can trust SAAV Extend in as wide a range of environments as existing SAAV models.
Real-time measurements in real-world conditions
You cannot guarantee pristine conditions in the field when you need to perform your ShapeArray installation. That’s why SAAV Extend's connectors have a 300-psi open-face pressure rating. You can connect segments in the rain without worrying about damaging your instruments.
Total control to monitor the zone of interest
Clients can use silent segments first introduced with SAAV, in addition to SAAV Extend's lift extension segments to target the total sensorized length towards the geologic zone of interest
Patented cyclical installation
SAAV Extend's patented cyclical installation system enables a stable fit into either new or distorted casings.

SAAV Extend
Your project site is not static, so you need geotechnical instrumentation that can adapt to new conditions. That’s why Measurand developed SAAV Extend to allow you to easily increase the length of your ShapeArray in the field as your needs change. This is ideal for situations such as increasing the height of a tailings dam. While a fixed-length instrument would have to be replaced entirely to accommodate the borehole’s increased length, SAAV Extend’s modular, connective design means that adapting your instruments is simple and more cost-effective.
SAAV Extend makes it possible for clients to add sensorized lift extension segments between a top assembly and the existing sensorized segments from the initial installation, known as the base array.
Clients don’t have to haul up the entire ShapeArray when to increase the total sensorized length. Just add the lift extension segments to the initial installation’s base array, along with the desired length of inclinometer casing. Re-attach the top assembly and the SAAV Extend is ready to continuously monitor deformation as the casing is back-filled.
SAAV Extend’s innovative, connectable design means clients can add or remove lift extension segments without ever needing to re-calibrate their ShapeArray.
Anatomy of SAAV Extend
SAAV Extend Top Assembly
The top assembly is the brain of the SAAV Extend that locks the instrument into standard inclinometer casing with Measurand’s patented cyclical installation method.
SAAV Extend Base Array
The base array refers to the sensorized segments at the bottom of the borehole after the initial installation.
SAAV Extend Lift Extension Segments
Lift extension segments added between the top assembly and base array connect to form the SAAV Extend’s total sensorized length.
