connected to the Internet, from any location in the world.

It also allows multiple authorized users at different

locations to view any data or report from the same project

site simultaneously. The graphs & reports can be viewed

using popular web browsers like Microsoft internet

explorer or Mozilla Fire fox amongst others.

The server for the above WDMS services is located at the

Encardio-rite premises and is maintained 24 x 7.

Model EVDV software is a powerful data base application

which provides a complete package for data storage,

Multilogger software

Mode l EDAS-10 automat ic data

acquisition system

Multilogger software is a Windows based software for

downloading and analysing data from CR-1000 based

EDAS-10 data acquisition system. Each measurement

channel can be configured for instrument type and

Model EAM-416 multiplexer

Multiplexer allows a number of sensors to be monitored by

a single data logger measurement and control module.

Wherever it is possible to house the data logger

measurement and control module and the multiplexer in a

single cabinet/housing, EAM-416 multiplexer is used. Each

EAM-416 multiplexer can connect up to 16 x 4-wire or 32 x

2-wire sensors sequentially to the measurement and

control module. Compatible sensors include vibrating wire

sensors, thermistors, potentiometers, resistive strain

gage type load cells, tilt sensors with voltage output, soil

moisture blocks etc.

The input lines to the multiplexer can be protected against

lightning induced high voltage transients using the ESP-

216 surge protector card. Each ESP-216 card can protect

up to 16 differential channels.

The complete system includes datalogger, multiplexers,

surge protectors, signal conditioners for vibrating wire

sensors, interface cables, power supply, transfer

softwares, etc. Units are available for up to

16/32/48/64/80/96/192 channels in different size

consoles

Surge protection is built into the BuxMux input and output lines; so

an additional surge protection card is not required.

In the SDI-12 networking system the sensors, multiplexers and

dataloggers are equipped with SDI-12 interface so that they can all

be connected together using a three conductor cable in a bus

arrangement. The SDI-12 system allows a huge reduction in

cabling costs as only a single three conductor cable is required to

interconnect the sensors, multiplexers and dataloggers in a

network that can be spread over a wide area.

Of the three conductors in a SDI-12 bus cable, one conductor acts

as the reference ground (or signal and power supply common), one

conductor is used for transferring the actual digital signal (0-5V

signaling level) and the third conductor is used to carry 12 V DC

power from the datalogger to the SDI-12 interface equipped

sensors and multiplexers.

The SDI-12 sensor networking system components include

Datalogger with SDI-12 interface - CR-1000 or CR-200

Vibrating wire SDI-12 interface (with surge protection) -

model EVM-108 8 channel (8 x 4 wire, 16 x 2 wire) or model

EVM-101 single-channel used with EAM-416 multiplexer to

connect 16 x 4 wire or 32 x 2 wire sensors.

Model EAM-405B BusMux based system

The EAM-405B BusMux multiplexer can be spread out over a

distance of hundreds of meters from the datalogger and requires

only a single 8 core cable for interconnection in a daisy chain

pattern. This results in a lot of saving in cable cost as wire from

individual sensors are terminated at the nearest BusMux and does

not have to be individually carried to the central datalogger

especially when in a project remotest sensors are some hundreds

of metres from the central datalogger.

BusMux can sequentially multiplex up to 5 x 4-wire or 10 x 2-wire

sensors. These can be field mounted, thus eliminating use of

junction box/switch box. Another advantage is that by using

BusMux it becomes easy to add more sensors to network that had

not been planned for earlier. As the bus multipliers are connected in

a daisy chain fashion one only needs to split or extend the bus cable

to make connection to the additional bus multiplexers (with some

extra cabling and editing in datalogger programming).

ER InclinoView software has been

designed to process borehole data from

Encardio-rite's EAN-26M digital

inclinometer. It is suitable for plotting

mean deviations, absolute borehole

profile, cumulative deviation against

depth and time vs deviation and vector

plots at each depth. It can also plot

checksums for assessment of quality of

data. Plots can be easily switched

between top or bottom reference. The

plots can be viewed along inclinometer

casing grooves or along a skew angle.

Spiral correction can also be applied if

such data is available.

InclinoView allows inclinometer data for

the same borehole to be automatically

correlated for excavation or fills and

benchmark elevation or fill levels with

date can be annotated on the plots. Sub

soil stratigraphy layers can also be

marked on the plots together with user

comments.

InclinoView allows data from a large

number of boreholes from different sites

to be organized and stored on the users'

PC. InclinoView can run on both

Microsoft Windows (XP and later

operating systems) and Linux platforms.

Model EAN-51M/52M vertical in-placeinclinometer system

EAN-51M is used for real time

monitoring of lateral movement and

deformation of earth works or a

fitted with a pair of pivoted sprung

wheels. A string of sensors can be

positioned inside a casing for a complete

deflection profile, using a suspension kit

and placement tube. A suspension wire

rope is also available in case deflection

profile of only part of casing is to be

monitored

EDI-52M in-place inclinometer system

provides a solution in which each

sensor is equipped with SDI-12 interface.

A single 3 conductor bus cable therefore

needs to be threaded in a daisy chain

fashion, connecting each sensor to its

next immediate neighbour and finally to

the top of the borehole and directly to

the da ta l ogge r (w i thou t any

multiplexer).

Several strings of EAN-52M in-place

inclinometer sensors in different

boreholes can be terminated in a single

Data Acquisition System with CR-1000

measurement and control module.

Consult factory as conditions apply.

For IPIs using a large number of sensors,

SDI-12 equipped in-place sensors are a

good choice as it will not be possible to

accommodate a large number of

individual signal cables inside the

borehole.
