SV 200 Noise Monitoring Station is a fully integrated solution for unattended noise monitoring applications featuring an internal web server for system configuration, live data streaming, data management and battery powered operation providing true flexibility for both short and long term measurements. The measurement capabilities of the SV200 are optimized for noise monitoring applications. It measures and stores results suitable for automatic reports,detailed information for advanced post-processing analysis and streams live data stream for real time noise monitoring. Standard measurement functionality includes multi-profile data logging, real time 1/1 and 1/3-octave logging, audio event recording and statistical analysis. Measuring capabilities can be extended with real time audio streaming and weather condition monitoring. SV 200 can be used for both and 0° and 90° reference direction, typically used for aircraft and environmental noise. The reference direction is user selectable in the instrument configuration. The weatherproof housing protects SV 200 noise monitoring station against extreme weather conditions while fulfilling class 1 accuracy. Special attention was given to the highly efficient windscreen which reduces noise, even at high wind speeds. Internal heating and rugged a dual layer housing enables the SV 200 to operate from -30°C up to +60°C and humidity up to 99% RH. SV 200 has a 2,45 Ah internal Li-Ion battery and interface for connecting solar panels. A waterproof mains adapter for charging the battery and powering the station is also included. The system is specially designed for easy installation - SV 200 is small, light weight and easy to install by a single person. The SV 200 is available with an integrated low power 3G modem or Wi-Fi access point. The implementation of advanced and highly reliable communication protocol gives the user full control of the station, offers easy to use data transmission, real time data publication and live audio streaming. Station configuration and data management is done by using a web browser or the SvanPC++ RC server application. | Standards | Class 1: IEC 61672-1:2013, Class 1: IEC 61260:2002 | | Number of Profiles | 3 | | Weighting Filters | A, C, Z | | Time constants | Slow, Fast, Impulse | | RMS Detector | Digital True RMS detector with Peak detection, resolution 0.1 dB | | Microphone | Microtech Gefell MK 255, 50 mV/Pa, prepolarised 1/2" condenser microphone | | Preamplifier | Integrated | | Linear Operating Range | 25 dBA RMS ÷ 133 dBA Peak (in accordance to IEC 61672) | | Total Dynamic Measurement Range | 15 dBA RMS ÷ 133 dBA Peak (typical from noise floor to the maximum level) | | Internal Noise Level | less than 15 dBA RMS | | Dynamic Range | >115 dB | | Frequency Range | 3.5 Hz ÷ 20 kHz with GRAS 40AE microphone | | Meter Mode Results | SPL, Leq, SEL, Lden, Ltm3, Ltm5, LMax, LMin, LPeak
