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.
To monitor a zone, you can attach as many noise level loggers along the pipe as you
wish. They then perform regular noise measurements within a certain time window. The
user can set the exact measurement time window and other parameters before
measuring begins. The level and frequency of the individual measurements are saved in
the logger. Even the quietest noise is saved as an audio recording.
After measuring, you can collect the loggers, call up the readings and check for leak
noises, and then put them back in a new zone, for example. This allows all the zones in
a pipe system to be checked in succession for leaks.
However, the loggers can also be left in the same zone to monitor it permanently. The
measurements from the individual loggers are then read out on site. Just approaching
the installed loggers with the Commander or another reader will suffice. Wireless data
transfer takes place automatically. Ideally, all you have to do is drive by where the
loggers are being used.
The Sebalog N-3 system has the following features:
• Loggers can be used temporarily, permanently or in the network
• Wireless communication between all components
• Audio data recorded directly in the logger
• “Commander-3” with colour display, USB port, large memory capacity, and
much more.
• Complete group/logger management without a PC
• History function
• Extended wireless range using repeater
• Logger available as TNC version with external antenna
