ShapeArray SAAX

Description

Purpose-built for heavy-duty horizontal measurement: soil settlement, rail-line deformation, and pipeline monitoring. SAAX’s watertight construction combines twist-resistant joints and thick-walled stainless steel segment tubes. The construction contains a compact array of MEMS accelerometers.

SAAX 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. SAAX is rolled off a reel and set into user-installed conduit.

SAAX’s segment length is 1000 mm. SAAX can be manufactured to a maximum length of 150 m. All ShapeArrays are manufactured in an ISO 9001 certified facility.
