Description

Intelligent Data Logger with Integrated Cellular Modem

The new Series 4 version has increased sampling speed, measurement range and programmable analog output.

The dataTaker DT82EM intelligent data logger is a fully featured low-powered logging platform with an integrated cellular modem, making it perfect for remote applications. The rugged design and wide operating temperature range of the DT82EM provides reliable operation in virtually any environment.

The DT82EM’s perfect balance of performance with low-power also allows you to use a smaller solar panel without compromising on functionality.

Versatile Measurement

Connect an array of sensors through the versatile analog and digital channels, high-speed counter inputs, phase encoder inputs and programmable serial sensor channels.

Temperature, voltage, current, 4-20mA loops, resistance, bridges, strain gauges, frequency, digital, serial and calculated measurements can all be scaled, logged and returned in engineering units or within statistical reporting.

Set up sampling, logging, alarm and control tasks to suit your own requirements while interfaces for smart sensors, GPS and other intelligent devices expand the DT82EM flexibility.

Automatic Data Delivery

Forget traveling long distances to get your data. Utilize the DT82EM’s automatic data delivery features to schedule your data to be automatically emailed to your inbox every day, week, month or other time interval.

More sophisticated systems can make use of the automatic data delivery features to send logged data to an FTP server. Alarm conditions can also trigger data delivery in addition to sending alarm messages to multiple email addresses or mobile phones.

Easy to Configure

The DT82EM is confi gured directly in your web browser using dataTaker’s dEX graphical interface. dEX takes you through the configuration of your logger, showing you wiring diagrams and allowing you to decide – in as much or as little detail – how you want the system to work, suiting both novice or advanced users.

Using the internal modem you can even re-configure your system remotely over the internet if required.

Software

dEX data logger software is an intuitive graphical interface that allows you to configure your data logger, view real-time data in mimics, trend charts or tables and retrieve your historical data for analysis.

Browser-based Solution

dEX comes pre-installed on every logger in the DT80 range. The software loads in your web browser so there is no need to install cumbersome applications on your computer. Being browser-based, dEX will work on all major operating systems including Windows, Mac and Linux.

Configuration Editor

The configuration editor allows you to view, edit and save logger configurations in an easy-to-use Windows Explorer style user interface. The configuration tree view allows definition of measurement schedules and measurements.

Wiring diagrams show available wiring configurations for each sensor type. Configuration can be stored and retrieved on either the logger or a local computer.

Mimics and Charts

Mimics are organized into panels which can be modified to highlight custom alarm conditions or data grouping. Mimics include dials, bar graphs, thermometers, etc. Real-time chart recorder mimic allows you to view trends and historical data over a custom time/date range. Up to 16 mimics can be displayed on up to 5 mimic pages.
