Geotechnical Inclinometer

Name: Geotechnical Inclinometer
Brand: Avans Tech

The geotechnical inclinometer is a traversing probe lowered through grooved casing to survey lateral movement with depth. The probe is IP68 at OD 25 mm by 758 mm long and reads plus minus 30 degrees at 0.001 degree resolution, with accuracy of plus minus 0.01 degrees between 0 and 12 degrees. It is supplied with 6.6 mm cable, 60 m as standard.

Product Overview

The geotechnical inclinometer is a traversing probe lowered through grooved casing to survey lateral movement with depth. The probe is IP68 at OD 25 mm by 758 mm long and reads plus minus 30 degrees at 0.001 degree resolution, with accuracy of plus minus 0.01 degrees between 0 and 12 degrees. It is supplied with 6.6 mm cable, 60 m as standard.

Materials

Stainless probe body with guide wheels
Marked survey cable

Key Benefits

Full displacement profile with depth from a single survey run
Resolution 0.001 degrees with repeatability of plus minus 0.003 degrees
IP68 probe for surveys in water-filled casing
One probe can serve many boreholes across a site, which keeps instrumentation cost down
Zero temperature drift of plus minus 0.002 degrees per degree C from minus 20 to 60 degrees C

Application Scenarios And Who It Is For

Application Scenarios

Periodic surveys of slope and landslide monitoring holes
Deep excavation and retaining wall movement checks
Embankment, dam and abutment monitoring
Pre and post construction deformation baselines

Who It Is For

Geotechnical monitoring contractors
Consultants running periodic survey programmes
Mining and slope stability teams
Contractors verifying retaining wall performance during excavation

Problems It Solves

Knowing that a wall moved but not at what depth
Instrumenting many holes where a permanent string in each is not affordable
Survey data that cannot be repeated reliably between visits
Probe seals failing in water-filled casing

Comparison With Other Products

Compared With	Why This Product
In Place Inclinometers	The traversing probe gives the full profile on each visit, the in place string gives continuous data at fixed levels
Manual surface survey	The probe survey resolves movement by depth rather than only at ground level

Use Guide

Check the casing is clear and the grooves are aligned before the first survey
Lower the probe to the bottom and take readings at fixed intervals on the way up
Repeat in the reversed orientation to cancel probe bias
Keep the same interval and datum on every survey so results compare
