This product line has been discontinued, a replacement will soon be introduced into the Omega catalog. As a potential alternate available now, please see OM-CP-OCTPRO as an alternative
Please check out Newest Released 24 plus channel Ethernet Data Logger OM-240 Series for more advanced features.
The OM-SQ2040 Series combines a higher channel count with the same
high performance, comprehensive features and universal inputs as the
OM-SQ2020 in a neat compact and portable instrument.
Using multiple 24-bit analog to digital convertors, twin processors and
removable memory options provide great flexibility to handle a wide range
of complex and demanding multichannel applications.
The OM-SQ2040 series are the ideal data loggers for industrial,
scientific research and quality assurance applications.
The OM-SQ2040 provides standalone data acquisition, advanced
networked solutions and data analysis straight out-of-the-box.
The OM-SQ2040-2F16 data logger has two analog to digital converters
(A/D’s) which increases logging flexibility over the OM-2020-1F8
model. The first corresponds to inputs on blocks A, B, C and D and
the second corresponds to inputs on blocks G, H, J and K.
Each connection block will accept up to 2 differential inputs or up
to 4 single-ended inputs (it is not possible to mix single ended and
differential inputs on a block).
The OM-SQ2040-4F16 data logger has four analog to digital converters
(A/D’s) which increases logging flexibility over the other OM-SQ2020
and OM-SQ2040 models. The first corresponds to inputs on blocks A
and B, the second corresponds to inputs on blocks C and D, the third
corresponds to inputs on blocks G and H and the fourth corresponds
to inputs on blocks J and K. Each connection block will accept
up to 2 differential inputs or up to 4 single— ended inputs (it is not
possible to mix single-ended and differential inputs on a block).
The OM-SQ2040 series uses |multiple analog to digital converters
that enables true concurrent sampling and logging. This allows the user to
configure up to 4 channels to log at a rate of 100 Hz while retaining different
sample speeds on other channels. This makes the OM-SQ2040 ideal for
measuring dynamic parameters that change at different rates such as
temperature and pressure.
Ethernet, Wi-Fi (on the OM-SQ2040-2F16-WIFI and OM-SQ2040-4F16-WIFI)
USB and RS-232 serial ports are built-in.
This allows quick connection to either a PC based TCP/IP network,
a wireless to PC connection or to a modem for remote data downloading.
This flexibility enables global data access and retrieval as well as
complete system integration of the OM-SQ2040 series into complex
and critical applications.
Multiple Configurations Stored in the Logger:
Up to six logger configurations (channel type,
names, logging speeds, triggers, etc.), together
with the current configuration, can be held in the
logger’s internal memory. Additional configuration
settings can also be loaded from the external
MMC/SD memory card. This allows the operator to quickly and easily
switch between logger configurations without
the need for a PC.
Comprehensive Software Configuration
The OM-SQ-SOFT software (supplied with the OM-SQ2040
series data loggers) allows logger
configuration, data download and data export while
giving the user full control over the OM-SQ2040.
The optional OM-SQ-SOFT-PLUS software gives the
user access to many advanced data analysis and data
archiving/transfer features. The optional OM-SQ-SOFT-PLUS
software lets you
quickly and easily analyze the data from your
OM-SQ2040 data logger in a familiar Explorer style
interface. Data can be displayed with 2 different auto
scaling Y-axis. This is particularly useful when
displaying widely varying data from different sensors on one graph.
You can also zoom in on areas of interest, use a
cursor to pick out exact values, times and dates, get
astatistical summary of your data, set high and low
alarm thresholds and, using the calculation function,
you can create new virtual channels from existing
The OM-SQ-SOFT-PLUS software also incorporates a
report generation facility, which allows you to create
custom report templates consisting of a title page with
descriptive text, headers and footers, graphs, tabular
list of data, statistics and data logger setup
information. Templates can be setup with any of these
combinations and saves time when preparing similar
presentations of data.
