Functionality and construction
The
SePem 100
and
SePem 150
loggers record sound. They
can gather and save data from water pipe networks. Data is ex-
changed with the
Master
by radio.
You will find an overview with the names of the logger parts inside
the front cover (Fig. 1).
Aerial
The only difference between the
SePem 100
and
SePem 150
loggers is their aerial. The aerial of the
SePem 100
logger is in-
tegrated in its housing. The aerial of the
SePem 150
logger can
be unscrewed.
Strap
A safety rope can be attached to the logger strap to make instal-
lation and removal at deep locations easier.
Mounting
The unit can be mounted on metal objects using magnets. If it
is necessary to monitor a plastic pipe then the logger must be
attached to the fittings.
Power supply
The power supply is provided by a permanently installed lithium
battery that has a guaranteed lifetime of several years under
normal operating conditions.
