SAAV is the most advanced ShapeArray model to date. Inspired by direct feedback from clients, Measurand developed a new installation method unique to the SAAV that allows the ShapeArray to be installed directly into existing conventional inclinometer casings or narrow conduit.
SAAV is ideal for retrofitting ShapeArray instrumentation into existing conventional inclinometer casings or for new installations in ungrooved casings or conduit. SAAV’s off-the-reel cyclical installation system (patent-pending) inserts the ShapeArray in a zigzag pattern into casings from 47 mm to 100 mm internal diameter (ID). The SAAV is then locked into place with a custom-designed spring box assembly. However, with a simple conduit adapter, SAAV can also install into 27 mm ID conduit, giving the client the flexibility to install SAAV in a manner that suits the project requirements. For situations where the SAAV is not required to reach all the way to the bottom of the casing, we offer silent segments for SAAV. Silent segments have no sensors inside and are connected at the far, non-cable end of the SAAV to increase the total length of the array. This innovation is useful when SAAV is installed into existing casings where the shear zones are known to be well above the bottom of the hole or to accommodate for casing depths that are not well known at the time of order.
SAAV contains upgraded MEMS sensors that reduce power consumption and improve resolution.
SAAV is available with 500 mm segment length segments, up to 150 metres long.
Purpose-built with longer one metre segments for heavy duty horizontal installation: soil settlement, rail-line deformation, and pipeline monitoring.
Short and long term
Purpose-built for heavy duty horizontal measurement: soil settlement, rail-line deformation, and pipeline monitoring. SAAX1000’s watertight construction combines twist-resistant joints and thick-walled stainless steel segment tubes. The construction contains a compact array of MEMS accelerometers.
SAAX1000 delivers superior cost-benefit returns to project budgets. All ShapeArray installations are fast and low-cost, requiring far fewer people than traditional in-place inclinometers. SAAX1000 is rolled off a reel and set into user-installed conduit.
SAAX1000’s segment length is 1000 mm. SAAX1000 can can be manufactured to a maximum length of 150 m. All ShapeArrays are manufactured in an ISO 9001 certified facility.
DISCONTINUED: SAAF is a versatile ShapeArray with a range of available segment lengths that enable tailoring of spatial resolution and maximum curvature. Ideal for long-term monitoring horizontally, vertically, or in an arc.

The SAAF is one of the most versatile types of ShapeArray that Measurand manufactures. SAAF measures ground and structural deformation, settlement, and subsidence. SAAF’s design—rigid stainless steel sensorized segments connected by flexible joints—is durable. SAAF may be installed near vertical to track the magnitude and direction of lateral deformation, or near horizontal to track vertical deformation.
SAAF is configurable with smaller segments than other ShapeArray models. Smaller segments mean data is sampled at more points, providing much higher spatial resolution of measurement data. Smaller segments also allow for greater curvature tolerance, making SAAF perfect for cross-section installation to monitor convergence in tunnels.
ShapeArray installation and removal is fast and low-cost, typically requiring far fewer people than traditional in-place inclinometers. ShapeArray is rolled off a reel and set into a narrow diameter PVC casing (27 mm), which is grouted into a borehole.
SAAF is available in 200 mm, 305 mm, and 500 mm segment-length configurations. SAAF can be manufactured to a maximum length of 150 m. All ShapeArrays are manufactured in an ISO 9001 certified facility.
