Vertical Array Structure

The Vertical Array Structure is an automatic inclinometer designed and optimised to monitor deformations in geotechnical structures (bulkheads, diaphragms, piles and micropiles) or viaducts. It consists of a sequence of IP69 hermetic nodes joined by a fibreglass rod, which preserves their alignment, and connected by a four-pole signal cable. Each node contains a high-resolution 3D MEMS sensor and a thermometer. The number of measuring sensors, the spacing and the length of the instrument can be defined according to the project requirements. It can be operated via the G802, G301 or any other data logger that is compatible with the RS485 Modbus RTU protocol.

INSTALLATION
The Vertical Array Structure can be installed in different ways. For example, it can be cemented directly into the structure during the construction phase or it can be placed on the external surface of the structure being monitored using special connection devices. If the monitoring requires a retrievable instrument, please refer to the Vertical Array R page.

PRINCIPLE OF OPERATION
Knowing the distance between the nodes, the position in space of the sensors calculated using the data recorded by the MEMS, and the orientation with respect to north using the data from the magnetometer, it is possible to identify the relative position of the instrument in space and consequently the displacements of the slope using special algorithms.
