1 INTRODUCTION
The EAN-26MH horizontal inclinometer system is designed for long term monitoring settlement profile of
structures like landfills, embankments, rafts or base slabs, storage tanks. The system is installed below
the structures to study the behavioural changes particularly during the testing stage and also during its
operating life, if required.
The horizontal inclinometer system provides significant quantitative data on magnitude of settlement and
its variation with time. It gives information on pattern of settlement and effectiveness of construction
control measures. It helps in monitoring behaviour after construction and indicates potentially dangerous
conditions that may adversely affect stability of the structure, its foundation and surrounding area. It also
provides basic data for design improvement that will promote safer and economical design and
construction.
The EAN-26MH digital inclinometer system is an accurate instrumentation system. Its readout has built-in
data storage facilities and capability of transferring stored data to a computer. The inclinometer probe
operates in an ABS plastic grooved casing which may be inserted into boreholes underneath the
structures. The inclinometer casing may be installed with fixed couplings as construction progresses
providing opportunity for settlement measurements.
1.1 EAN-26M Digital Inclinometer Overview
The Encardio-rite model EAN-26MH Digital Inclinometer uses an Android OS based mobile phone with a
Bluetooth wireless interface as a readout device. The recommended phone types have a large pixel with
colour display and a capacitive touch screen that makes it easy to read the display while logging bore
holes using Encardio-rite’s range of horizontal borehole inclinometers.
Few functional advantages can be listed as follows:
•
The readout unit can store readings from up to more than 1000 bore holes. The readings are not lost
even if the power is turned off.
•
Four readings are required for a uniaxial inclinometer survey for each depth level in a bore hole (as
will be explained in the manual). In case of any error during logging, the probe can be inserted back
to the distance with problem and logging can be continued without having to start afresh, thus saving
time.
•
A quick probe check mode allows verifying probe operation or calibration without having to configure
a dummy borehole log as is required by most other commercially available inclinometer data loggers.
•
The stored readings can be uploaded to a remote FTP server using GPRS/3G cellular network. The
uploaded data is in a format that allows the data to be easily imported in spread sheet program like
Microsoft Excel
.
Since readout unit is a mobile phone, most of the people are familiar with its operation. Working with a
mobile phone readout unit is very easy and user friendly.
