Inclinometer casing is a special grooved tube, generally installed into a borehole, used in cinjuctions with inclinometer system to determine sub-surface ground or horizontal soil movements.
The inclinometer casing performs the following main functions:
-it reflects deformations of soil or rock into which it is installed or in structures to which it is attached;
- it provides a precise casing for the operation of the inclinometer probe in the determination of inclination changes;
Its internal grooves provide orientation reference for the inclinometer probe.
Inclinometer casing is produced in different materials as aluminium, fiberglass and ABS (acrylonitrile-Butadiene-Styrene).
