WiFi Geotechnical Data Logger - dataTaker DT85GW

The DT85GW WiFi Geotechnical Data Logger has been designed based on 25 years of geotechnical expertise as well as advanced design and technology. It is a versatile, robust, low power and cost-effective logger.

It supports vibrating wire and other geotechnical sensors such as RST Instruments, Roctest, Geokon, Slope Indicator, Soil Instruments, AGI–Applied Geomechanics Inc. The DT85GW can also test sensor integrity via audible frequency.

With temperature compensation (thermistor), 16 analog channels are capable of reading up to 16 vibrating wire sensors. If temperature compensation is not needed, this logger is designed to read up to 48 vibrating wire sensors.

Additional expansion of up to 960 sensors (without temperature compensation) or 320 sensors (with temperature compensation) is possible.

  • Vibrating wire support
  • Strain gauge support
  • Carlson, Electro Level and LVDT support
  • Up to 48 Analog (± 50V) sensor inputs
  • Expandable to 960 analog inputs
  • Dual Channel Isolation Technology
  • Programmable analog output
  • Integrated WiFi
  • Web and FTP client/server
  • Modbus for SCADA connection
  • Automatic data transfer via email or FTP
  • USB memory for easy data and program transfer

Local Wireless Access

With wireless access, there is no need to have a physical connection to the logger. Transfer the program, view and download the data, or even alter the setting on adjacent PC or Tablet wirelessly either as a Master (Access Point mode) or Slave (Client).

Automatic Data Delivery

On Client mode the dataTaker can have access to a local router, and if the router has internet access it can make use of the DT85GW’s automatic data delivery features to schedule the user’s data to be automatically emailed to personal inbox daily, weekly, monthly, or at other time intervals.

More advanced systems can utilize the automatic data delivery features to transfer logged data to an FTP server.

Superior Data Storage and Communications

With the basic unit capable of storing up to 10 million data points (expandable), users can log as much or as little as they need. Overwrite or stop logging once allocated memory is filled up, archive data on alarm event, copy to USB memory, or transfer via FTP/Email—the choice lies with the user.

Communications features include USB, RS232, and Ethernet, connect to the DT85GW locally, remotely over the Internet or via a modem. The web interface enables users to configure the DT85GW, access logged data, and view present measurements as mimics or in a list with a web browser.

FTP/Email provides data to the user’s office over the wireless network or internet, without the need for  particular host software or polling.
