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.

Overview

Segment Length:
200, 305, and 500 mm

Installation:
Horizontal/Vertical/Convergence

Applications:
All-purpose shape monitoring

Project Duration:
Short and long term

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.

SPEAK WITH TECHNICAL SERVICES

"After several installations, we were really satisfied that SAA provided continuous deformation profiles and reliable data in our pile lateral loading tests."
