Shape Accel Array (SAA)

Getec use the Shape Accel Array  manufactured by Measure and  for accurately monitoring retaining walls, large slab movements , sewer deformation and drilling inclination monitoring.

The SAA can also be used for vibration monitoring. SAA is a string of rigid segments separated by joints that can move in any direction but cannot twist. MEMS gravity sensors measure tilt in two directions. Processors transform the position (e.g. X,Y & Z) of each sensor to produce shape and change of shape. The SAA data can be used directly in the  gtcVisual monitoring software and with our SAA Viewer app that is integrated into gtcVisual , standalone PC , I phone, I Pad and all android platforms.
Getec have successfully used the SAA to measure retaining wall movement, slab heave and settlement , tank base movement , sewer movement , and drill positioning.
