Efficient:
The Unilog is especially characterised by its low energy consumption as well as by its intelligent power management. The power can be supplied (depending on the infrastructure) with a 12 V battery, solar panel or an external 230 V/ 12 V DC power supply unit.

Variable:
Depending on the measurement task, up to 32 logical channels can be managed by the logger. So, for example, it is possible to connect 16 digital DS(T) 22 type SEBA-pressure / temperature probes, or three MPS-D8 multiparameter sensors via the internal RS485 interface. Using an external A/D converter, up to 32 analog sensors can be connected.

Smart:
An alarm management system in Unilog monitors all of the channels. When exceeding predefined thresholds, (for instance during a flood) the measurement intervals can be automatically shortened. Furthermore, when combined with an external modem, shorter transmission intervals (Dynamic Push) are possible. Additionally, upon request, short messages (SMS Alert) can be sent to up to eight receivers.

User-friendly:
Two APPs are available for configuration and data readout of UniLog. Operating software ConfigPC (Windows) for beginners has an intuitive user interface (Wizard) for various routine tasks. SEBAConfigApp (Android) and BlueCon (our Bluetooth module) are combined to facilitate configuration and data read-out wirelessly with a smartphone or tablet, directly from a data logger.

  • Level measurement in watercourses, lakes, reservoirs
  • Filling level measurement in flood control reservoirs
  • Monitoring of thermal plumes, discharge monitoring
  • Supervision of landfill and waste disposal sites in connection with multi-parameter sensors
  • Groundwater monitoring in wells, at field measurement and construction sites
  • Acquisition of meteorological parameters from weather stations
