1. INTRODUCTION
SV 271 LITE
is an outdoor monitoring station
based on the
SVAN 971
Class 1 sound level
meter and
SA 271
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
using 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 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 271 outdoor kit protects the
SVAN 971
preamplifier and microphone from weather
conditions. The SA 271 is made of lightweight
materials and can be easily installed on a mast
with standard mounting threads.
SVAN 971 can be easily removed from the station case and used as a hand-held
sound level meter.
