Inclinometer Casing

Geonor, Inc - Precision Instrumentation

Overview

RST’s Inclinometer Casing is engineered to be assembled quickly and accurately for long and short term monitoring in the most adverse field conditions. RST Inclinometer Casing is suited to be installed in boreholes, embankments, piles, set into concrete or attached to structures. It’s compatible with all commercially available inclinometer probes, including RST’s MEMS Digital Inclinometer Probe. RST manufactures Inclinometer Casing with precision CNC technology.

The casing serves as an access tube to guide a MEMS-based inclinometer probe in the two orthogonal directions of measurement. Changes in the output of the probe caused by the deformation of the casing, is proportional to the sine of the angle of inclination of the long sensor axis from vertical. These displacements are incrementally summed to provide profiles of total displacement versus depth.

RST Instruments manufactures two sizes of Inclinometer Casing, with two integral coupling styles, to provide alignment and displacement measurements in numerous applications.
