Svantek SV 258 PRO Vibration & Noise Monitoring Station
The new SV 258 PRO is dedicated for building vibration measurement that use methods based on Peak
Particle Velocity and Dominant Frequency. The measurement of human vibration in buildings is possible
as the program 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.
Users can use predifined settings compatible with commonly used standards such as DIN 4150-3 or BS
7385-2 or configure a criterion curve based on FFT or 1/3 Octave analysis in accordance with local
standards.
The vibration time history in the form of WAV is stored for all three channels and is used for verification
of vibration sources. Accurate post-analysis of the frequency content of the signal is available in the
SvanPC ++ program.
The built-in GSM modem transmits measurement data to the SvanNET server where the user has
access to current data, files with historical data and can also generate a measurement report. The
system generates SMS and Email notifications as well as visual and audible alarms. In addition to simple
triggers from PPV or LEQ values, the you can configure alarms from standard curves (e.g. DIN 4150-3)
or custom curves based on FFT or 1/3 octaves. It is possible to move the criterion curve up or down the
scale so that the alarm is generated earlier or later. The time and value of the alarm are saved together
to the memory of the meter.
SV 258 PRO is an outdoor monitoring system based on SVAN 958A Class 1 sound level meter. 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 small solar panel. The
intelligent charging unit enables use of a solar panel without expensive controllers and heavy batteries.
The 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.
