The portable data logger of the OM-SQ2020 Series combines high
performance, powerful features and universal inputs in a compact and
easy-to-use instrument. Using high accuracy 24-bit analogue
to digital converters, removable memory and Ethernet networking
(on the OM-SQ2020-2F8), the OM-SQ2020 Series is the ideal data
logger for industrial, scientific research and quality assurance
applications. Together with our comprehensive suite of software,
the OM-SQ2020 provides standalone data acquisition, realtime
metering and data analysis straight out-of-the-box.
Input Connections
The OM-SQ2020-1F8 data logger has a single analogue to digital
converter (A/D) which corresponds to inputs on blocks A through to D.
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-SQ2020-2F8 data logger
has two analogue to digital converters (A/D’s) which increases logging
flexibility over the OM-SQ2020-1F8 model. The first corresponds to
inputs on blocks A and B and the second corresponds to inputs on
blocks C and D. 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).
Concurrent Sampling
The OM-SQ2020 Series uses multiple analogue to digital converters
that enables true concurrent sampling and logging. This allows the user to
configure a channel to log at a rate of 100 Hz (20 Hz on OM-SQ2020-1F8)
while retaining different sample speeds on other channels. This
makes the OM-SQ2020 Series ideal for measuring dynamic parameters
that change at different rates such as temperature and pressure.
Communications
Ethernet (on OM-SQ2020-2F8), Wi-Fi (on OM-SQ2020-2F8-WIFI), USB and RS-232 serial ports are
built-in. This allows simple connection to either a PC based
TCP/IP network, a wireless to PC connection or to a GSM modem for
remote data downloading. This flexibility enables global data access
and retrieval as well as complete system integration of the
OM-SQ2020 series into complex and critical applications.
Multiple Configurations Stored in the Data 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-SQ2020 series
data loggers) allows logger configuration, data download and
data export while giving the user full control over the OM-SQ2020.
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-SQ2020 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 a
statistical summary of your data, set high and low
alarm thresholds and, using the calculation function,
you can create new virtual channels from existing
channels. 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.
