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.
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).
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.
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.
For technical specifications, see the spec sheet in the "Downloads" section.
If you are interested in temperature calibration, also select the appropriate temperature probes for the required number of channels.
Technically speaking, a data logger is any device that can be used to store data. This includes many data acquisition devices such as plug-in boards or serial communication systems which use a computer as a real time data recording system. Most instrument manufacturers, however, consider a datalogger a stand alone device that can read various types of electrical signals and store the data in internal memory for later download to a computer.
The advantage of data loggers is that they can operate independently of a computer, unlike many other types of data acquisition devices. Data loggers are available in various shapes and sizes...
