1. INTRODUCTION
SV
277 PRO
is an outdoor monitoring station
based on the
SVAN 977
Class 1 sound level
meter and
SA 277
outdoor microphone kit. The
solution is recommended for short term and semi-
permanent
noise
measurement
in
the
environment.
The IP
67 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 allows you to measure results, such
as Leq, Max, Min and Peak, with all standard
weight filters and with history recording with two
registration steps. The results can be obtained for
three profiles - virtual sound level meters, allowing
parallel measurements with three different filters
(for example, A, C, Z), as well as with three
different RMS detector time constants (for
example, Fast, Slow, Impulse).
The SA 277 outdoor microphone kit protects the
SVAN 977 preamplifier and microphone from
weather conditions. SA 277 is made of lightweight
materials and can be easily installed on a mast
with standard mounting threads.
SVAN 977 can be easily removed from the station case and used as a hand-held sound
level meter. The monitoring station uses a mobile 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.
