The SV 200A is a unique Noise Monitoring Terminal (NMT) which includes in
a single portable housing: outdoor microphone, sound level meter and 1/1 &
1/3-octave analyser, advanced logger, sound direction detector and
communication systems (3G modem, Bluetooth, LAN and WLAN). This
system can be easily transported and installed by one person in the field
conditions.
The instrument is an ideal choice for an unattended permanent and semi-
permanent environmental noise and weather monitoring. Instrument can be
used for community and airport noise monitoring.
The system enables easy communication, data download and configuration
using PC or mobile device over the Internet or local network.
SV 200A meets Class 1 requirements of IEC 61672-1:2013 standard and
provides broad band results with all required weighting filters, 1/1 octave &
1/3-octave spectra with complete statistical analysis.
Instrument can be easily calibrated in-field using sound calibrator. Built-in
electrostatic actuator can be activated remotely or periodically in automated
mode for self-testing.
SV 200A enables great logging capability which includes time history of broad
band results and spectra with two selectable logging steps down to
2 milliseconds and audio recording on trigger of different types. Data are stored
in the instrument’s memory and can be transferred over the internet on demand
or in automatic mode.
Remote communication option for the SvanPC++ software and the SvanNET
web-server provides advanced communication with files downloading, data
visualization and measurement results exporting. Environmental monitoring
option for the SvanPC++ software is dedicated for measurement data
management, advanced data processing, analysis, visualization and reporting.
Thanks to robust casing, protection against overheating & humidity
condensation, built-in rechargeable battery, this instrument is excellent for
permanent installation in all environmental conditions.
Thanks to four MEMS microphones built into the body of SV 200A you can
detect the source of the dominant energy occurs in two planes - horizontal "XY"
and vertical "Z".
