The data logger has now b

come the indispensable tool for anyone r

quiring to monitor and record factory pr

cesses or environmental conditions automatically. Stand

lone data logger systems are now

sed throughout the manufacturing, chemical, oil and g

s, water and power generation industries. D

ta logger units are also commonly

sed for industrial R and D, m

dical research, and environmental monitoring.

However, whilst it is v

ry useful to use a data l

gger to record a process, or

nvironmental conditions. The data is no use

nside the data logger, it has to be d

wnloaded to a PC to be v

ewed by the relevant users. Typically a

ser will take a laptop PC to the s

te and connect directly to the d

ta logger to download the data. Th

s is OK where the site is n

arby and data does not need to be d

wnloaded very often, but for remote s

tes, or where the data logger n

eds to be downloaded often this is not v

ry practical.

Many types of data logger now

ncorporate various means of remote communication to

nable the data to be collected w

thout a site visit. These can be s

mmarized as follows:

Data logger remote communication via GSM.
The d

ta logger is fitted with a GSM m

dem so that the host PC can c

nnect over the worldwide GSM network.

Data l

gger remote communication via GPRS
The data l

gger is fitted with a GPRS m

dem and data is transferred via the

nternet utilizing the worldwide GPRS network

Data l

gger remote communications via SMS text m

ssaging
The data logger sends it’s data at r

gular intervals or on alarm via SMS t

xt message. This is ideal for sm

ll amounts of data, such a d

ily totals from water meters, gas m

ters or electricity meters.

Data logger remote c

mmunications via Ethernet
The data logger connects d

rectly via Ethernet TCP/IP to a h

st PC or network. Some data l

gger models are also able to p

blish web pages directly to the

nternet

Data logger remote communications via low p

wer radio
The data logger connects to the h

st PC using license free low p

wer radio. Ranges up to 10 KM can be

chieved with this method.

Using remote data

cquisition solutions such as these OEM m

nufacturers have the option to monitor

quipment for fault conditions almost anywhere in the w

rld. A typical example is of a m

nufacturer of steel mill equipment based in the UK b

ing able to monitor faults in

t’s equipment installed in a mill in Ch

na. Where once an engineer would h

ve been sent from the UK to Ch

na to investigate a potential fault, now the

nitial diagnoses and remedial action can be c

rried out remotely saving time and c

nsiderable expense. Portable systems with built in GPRS are now

vailable as turnkey products, with the

bility to email logged data direct to a

ser’s inbox.

Omni Instruments has many years

xperience in providing remote data logging s

lutions for both machine and environmental m

nitoring together with relevant sensors for pr

cess measurement and also weather monitoring.
