DT85G - Intelligent Geotechnical Data Logger
Product Description
Supporting vibrating wire sensors the dataTaker DT85G 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 low cost, low power dataTaker DT85G is extremely versatile and easy to configure for communications, data capture and data analysis. View the data in real time or store up to 10 million data points. Data storage and retrieval can be achieved via USB memory stick, FTP, cellphone, Modbus for SCADA, Ethernet or Web.
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.
