1 INTRODUCTION
SV 258 PRO
is an outdoor monitoring system based on the
SVAN 958A class 1 vibration and sound four-channel level
meter dedicated for ground and building vibration
applications. The portable and battery powered station can
be used for a variety of monitoring applications including
construction site monitoring, tunnelling and blasting. The
IP 65 rated case contains a lead-acid battery which
operating time can be easily extended by connecting an
external battery or a solar panel. The intelligent charging
unit allows to use a solar panel without expensive
controllers and heavy batteries.
The station case is fitted with very robust, waterproof
connectors (military standard) and comes with an IP 65
external power supply. The system uses a low-noise,
hermetically sealed tri-axial piezoelectric accelerometer
enabling the outdoor use without additional enclosures.
The accelerometers' signal ground is insulated from the
mounting surface and outer case to prevent ground loops.
All accessories fit conveniently into a second carrying case.
The special firmware (SVAN 958AG) is dedicated for building vibration measurements and uses methods
based on Peak Particle Velocity and Dominant Frequency. Measurements of human vibration in buildings are
also possible as the instrument allows simultaneous measurement of velocity and acceleration of vibrations
with two independent steps of recording. In addition, it is possible to enrich the measurement with Class 1
sound results.
The monitoring station uses the 3G modem for the remote communication with the Internet. SvanNET, the relay
server, supports the connection between PC and the station allowing the usage of all types of SIM cards,
regardless if they have public or private IP. The use of SvanNET gives access to the status of the monitoring
station also via mobile phone or tablet.
