Digital In-place Inclinometer System

Geonor, Inc - Precision Instrumentation


Vertical In-place MEMS Inclinometer Systems are designed to measure lateral movement of soil and rock or deflection of man made structures such as piles or retaining walls, when remote and continuous monitoring is required.

In-place inclinometers consist of one or more MEMS inclinometer sensors housed in a 31.75 mm (1.25 in.) diameter, water-tight, stainless steel enclosure. Each sensor is separated from the next by stainless steel rods and wheel assemblies. Rod lengths can be varied to alter the gauge length and sensors can be concentrated in areas of expected movement.

Wheel assemblies are sized to fit 70 mm (2.75 in.) or 85 mm (3.34 in.) O.D. inclinometer casing. As movement occurs and the inclinometer casing deforms, each sensor can be automatically monitored and can be read at a remote readout location. If necessary, an alarm can be triggered when movement reaches a preset critical rate or magnitude.


  • Optional single cable digital BUS system.
  • Highly cost effective per sensor point.
  • On board electronics.
  • Removable.
  • High precision, wheeled probe.
  • Easily adaptable to datalogging.


  • Monitoring stability adjacent to excavations or underground workings.
  • Monitoring deflection of piles, piers, abutments or retaining walls.
  • Continuous, automated reading where early warning of movements is essential for protecting life and equipment.
  • Monitoring dams and embankments.
