It is VITAL that personnel responsible for the
installation and use of the In

Place Inclinometers
READ and UNDERSTAND the manual, prior to
working with the equipment.
1.1 General Description
The
Geosense
®
In
-
Place Inclinometer (IPI)
equipment is an environmentally sealed
assembly that is used to register changes of inclination within specialist inclinometer
casing. The assemblies are commonly interlinked and intended to remain static
within the inclinometer casing.
In
-
Place Inclinometers can be installed or included in many types of monitoring
regime and can be linked to various types of readout and recording equipment.
The primary uses of IPI
’
s are :
-
Measurement of Rotation within a vertical installation.
Measurement of Rotation within an inclined or horizontal installation.
With applications such as, but not limited to, the following :
-
Embankment stability and safety monitoring
Stability of retaining walls
Dam monitoring
Horizontal pile testing
Slope stability monitoring
Particular features of
Geosense
®
IPI
’
s are:
-
Reliable long term performance.
Ruggedness; suitable for demanding environments.
Simple, cable free interconnection.
High accuracy.
Digital output, therefore insensitive to long cable lengths and joints
The
Geosense
®
IPI is based upon Micro Electro Mechanical Systems technology
(MEMS). The MEMS sensors employed in the IPI is an accelerometer that is
configured to measure changes in rotation (tilt or inclination). IPI sensor modules an
be configured to include a Uni

axial sensor or a Bi
-
axial sensor, where the two
sensors detect inclination in perpendicular directions (A axis and B axis).
Electronic circuitry within each IPI module interrogates its sensor and the
corresponding output is converted from an Analogue to a Digital signal, making it
