Inclinometer Casing
RST’s Inclinometer Casing is engineered to be assembled quickly and accurately for long and short term monitoring in the most adverse field conditions, and is available in 2 connection types depending on the installation depth requirements.

Overview
RST’s Inclinometer Casing is suitable for installation in boreholes, embankments, piles, set into concrete or attached to structures.
The casing serves as an access tube to guide a MEMS-based Inclinometer probe or Digital In-Place Inclinometer Systems in the two orthogonal directions of measurement.
Key to quality Inclinometer Casing is not only the material, but the quality and shape of the grooves. The grooves are machined rather than using extruded methods to ensure tight tolerances of twist deviation over length. The Inclinometer probe utilizes these grooves in the casing to control the azimuth.
RST Inclinometer Casing is manufactured from non-recycled virgin ABS resin. While more costly than common PVC resin, ABS is preferred due to superior flexibility, stability and low temperature impact resistance. Using recycled resin degrades the performance of casing.
Product features
- High precision, machined guide grooves
- Groove Spiral tolerance ≤ 0.3 deg./10 ft (3m)
- Easy assembly
- Self-aligning, water and grout tight couplings
