Wireless Geotechnical data Logger

Geotechnical Logger

Advanced design and technology plus 25 years of geotechnical expertise have produced the dataTaker DT80GW GeoLogger – A versatile, powerful – yet low power & cost effective data logger.

It support vibrating wire and other geotechnical sensors such as Slope Indicator, RST Instruments, Geokon, Soil Instruments, Roctest, AGI – Applied Geomechanics Inc. DT80GW is also capable to test sensor integrity through audible frequency

With temperature compensation (thermistor), 5 analog channels are capable to read up to 5 vibrating wire sensors. If temperature compensation is not required this logger can read up to 15 vibrating wire sensors.

Further expansion up to 100 sensors (with temperature compensation) or 300 sensors(without temperature compensation) is possible.

  • Land slide prevention
  • Structural strength diagnosis
  • Dam-wall monitoring
  • Tunnel monitoring
  • Concrete curing
  • Mining exploration
  • Pipelines monitoring
  • Earthquake early detection

Local Wireless Access

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

Superior Data Storage and Communications

With the standard unit able to store up to 10 million data points (expandable) you can log as much or as little as you need. Overwrite or stop logging once allocated memory is full,archive data on alarm event, copy to USB memory or transfer via FTP/ Email, the choice is yours.

Communications features include RS232, USB and Ethernet, connect to the DT80GW locally, remotely through a modem or over the Internet. The web interface allows users to configure the DT80GW, access logged data and see current measurements as mimics or in a list using a web browser.

FTP/ Email provides data to your office over the internet or wireless network, without the need for polling or specific host software.

Central Market Abu Dhabi

The Central Market in Abu Dhabi is a huge construction project which is due for completion in 2011. It consists of three towers, the Residential Tower, the Commercial Tower and the Hotel Tower. The tallest will be the Residential Tower which will stand 381 metres tall with 88 floors. It is imperative that certain parameters identifying the structural integrity be monitored and logged during construction. The diaphragm walls also require monitoring during the construction period to ensure the safety of the people and equipment on-site…
