SV 258 PRO Vibration & Noise Monitoring Station

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, tunneling 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.
The system provides broad-band vibration results such as RMS and Peak or Peak-Peak. Optionally it can use FFT analysis for determination of dominant frequency used for comparison with the BS and DIN norm curves. The broad-band noise results can be recorded simultaneously in three acoustic profiles, which enable measurements to be taken with 3 different filters (e.g. A, C, Z) as well as 3 different detector time constants (e.g. Fast, Slow, Impulse).
The SVAN 958A can be easily removed from the case and used as hand-held vibration and sound level meter. The monitoring station uses the 3G modem for the remote communication with Internet. SvanNET, the relay server, supports the connection between PC and station allowing the usage of all types of SIM cards with the system, regardless if they have public or private IP. The connection over the SvanNET gives access to the status of the noise monitoring station via mobile phone or tablet.
