CAS DataLoggers has supplied a dataTaker DT80 Intelligent Universal Input Data Logger to an open-cut coalmine for monitoring the quality of high salinity water before being released into the river system.
The coal mine manages its high salinity water runoff in local retaining dams. This water can be released into the river only if its quality does not affect the irrigation in the surrounding areas. This made the management to look out for a versatile data logging solution to monitor multiple parameters.
A dataTaker DT80 Intelligent Universal Input Data Logger was installed and connected to various sensors capable of measuring water levels, turbidity, pH, salinity, and thermocouples for air and water temperature. The dataTaker was mounted in weatherproof enclosures and a solar panel was used to provide power to the DT80 device.
The wireless facility allows users to connect and monitor the changes in water quality. The data was stored in the mine’s office in a central PC. The FREE dEX software allows users to view real-time data and perform analysis. The data logger allowed the coalmine to monitor the various water quality parameters through a single device constantly in real-time.
The datalogger can be expanded to more channels and analog inputs. It can scale and log values from strain gauges, resistance, current, voltage, temperature and frequency. It has a built-in display and Ethernet, USB memory stick, USB and RS232 with modem support ports. The device features Modbus slave and master functionality, and FTP server and web enabled remote access.
