Monitoring Station SV 279 PRO
4
1. INTRODUCTION
SV
279 PRO
is an outdoor monitoring station
based on the
SVAN 979
Class 1 sound level
meter and
SA 279
outdoor microphone kit. The
solution is recommended for short term and
semi-permanent noise measurement in the
environment.
The IP 65-rated case contains a lead-acid
battery the operating time of which can be easily
extended by connecting an external battery or a
solar panel. The intelligent charging unit enables
the use of a solar panel without expensive
controllers or heavy batteries. The case is fitted
with very robust, waterproof connectors (military
standard).
The station provides broad-band results such as
Leq
,
Max
,
Min
and
Peak
with all standard
weighting filters together with an incredible time-
history logging feature with two adjustable
logging steps. The broad-band results can be
recorded in three acoustic profiles which enable
parallel measurements with 3 different filters
(e.g.
A
,
C
,
Z
) as well as 3 different detector time
constants (e.g.
Fast
,
Slow
,
Impulse
).
The SA 279 outdoor kit protects the SVAN 979
preamplifier and microphone from weather
conditions. The SA 279 is made of lightweight
materials and can be easily installed on a mast
with standard mounting threads.
SVAN 979 can be easily removed from the station case and used as a hand-held
sound level meter. The monitoring station uses a 3G modem for remote
communication with the Internet.
SvanNET
, a relay server, supports the connection
between PC and station. Thanks to SvanNET users may use a mobile phone or
tablet to check the status of the monitoring station.
