  • Page 7: Technical Description

    Technical description Technical description Function Sebalog N-3 is a system for acoustically monitoring pipe systems. It has Log N-3 noise level loggers and the Commander-3 as its basis. The Commander is used for programming the loggers as well as reading out and analysing the recorded measurements.
  • Page 8 Technical description Components The Sebalog N-3 system consists of the following components: Component Log N-3 measures regularly the volume level and frequency of the noise in noise loggers the pipe during the programmed measuring window. Commander-3 is the portable device for programming the loggers before measuring, and for reading out and analysing the recorded data after measuring.
