Data Loggers
Powerful Data Logger and Flexible Data Acquisition and Data Logging Systems

Networking dataTakers

>> Equipment
• dataTaker 515 data loggers
• Channel Expansion Modules
• Full Bridge Extensometers
• Hollow Inclusion Cells

>> Customer Requirement
To monitor ground movement or subsidence around a copper mine which is generally unstable, for the safety of miners and machinery. Early warning of danger situations is essential.

>> dataTaker Solution
dataTaker 515 data loggers with two Channel Expansion Modules were arranged in three groups, giving a total of 90 differential channels. The three groups are spread out through the mine, and are linked together by the dataTaker's builtin network.

The data loggers collect information from an array of extensometers and Hollow inclusion cells, and periodically transmit the data to a PC on the surface for analysis by custom software.

The PC is located 3 km from the installation, and so a RS485 communications link from the dataTaker network was installed.
