The Geo-technical Logger
Supporting vibrating wire sensors the new dataTaker DT80G GeoLogger is ideal for all geotechnical data logging applications. The dataTaker GeoLoggers have built-in vibrating wire support providing ideal data acquisition and monitoring solution for the engineer working in the geotechnical environment.
The dataTaker GeoLoggers can monitor a wide variety of geotechnical datalogging applications including slope stability, subsidence, dam wall monitoring, tunnel and mining excavation, ground water, tunnel wall monitoring and site assessment.
The advanced new dataTaker DT80G range Geologgers are compatible with all major brands of geotechnical instrumentation including Slope Indicator, RST Instruments, Geokon, Soil Instruments, Roctest, AGI - Applied Geomechanics Inc.
Communication Features
The low cost, low power dataTaker DT80G is extremely versatile and easy to configure for communications, data capture and data analysis. View the data in real time or store up to 5 million data points. Data storage and retrieval can be achieved via USB memory stick, FTP, cell phone, Modbus for SCADA, Ethernet or Web.
Universal & Configurable
The dataTaker DT80G has 5 analog channels capable of measuring up to 5 vibrating wire strain gauges with thermistors or 15 vibrating wire strain gauges without thermistors. If additional channels are required the dataTaker DT85G has 16/48 vibrating wire channels. The DT80G and DT85G can be expanded simply by connecting dataTaker Channel Expansion Modules (CEM20) to provide 100 to 300 vibrating wire channels with thermistors.
dEX Software
dEX 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.
dEX runs directly from your web browser and can be accessed either locally or remotely, anywhere that a TCP/IP connection is available including worldwide over the Internet. You can use any of the logger’s built-in communications ports to view dEX including Ethernet, USB and RS-232.
- Built-in software - no application to install
- Runs directly from your web browser
- Accessible by Ethernet or USB connection
- Intuitive graphical interface
- Easy-to-use configuration editor
- Access live and historical data
- View data charts, mimics and tables
Real Time Trending
Real-time trending for sensors, calculations or other data. Supports up-to 5 traces per chart and up-to 2 Y-axes. Backfills with historical data stored in logger.
Real Time Displays
dEX displays real-time sensor measurements, calculations and diagnostic information, including mimics, tables and trend charts
Configuration Made Easy
The configuration editor allows you to view, edit and save logger configurations in an easy-to-use Windows Explorer style user interface. Tree view of configuration allows definition of measurement schedules and measurements.
Wiring diagrams show possible wiring configuration for selected sensor type. Configuration can be stored and retrieved on either the logger or a local computer
