Probe Style In-place MEMS Inclinometer

Geonor, Inc - Precision Instrumentation


Standard in-place inclinometers may not be able to track in casings deformed by active ground movement. The Probe Style In-place MEMS Digital Bus Inclinometer has tracking equal to the best standard probe inclinometers.

The Probe Style In-place MEMS Digital Bus Inclinometer is designed to remotely monitor, and continuously measure, underground vertical movement as a result of construction and excavation and any settlement that may occur around tunnels, dams, embankments and landfills.
In-place inclinometers consist of one or more MEMS inclinometer sensors housed in a 25 mm (1.0 in.) diameter, water-tight, stainless steel enclosure. Each sensor is separated from the next by Kevlar® cable assemblies. Cable lengths can be varied so sensors can be concentrated in areas of expected movement.
Wheel assemblies are sized to fit both 70 mm (2.75 in.) and 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.
