Product Code: SV 258 Pro

SV 258 Pro Building Vibration and Noise

The SV 258 Pro is an outdoor monitoring system based on the SVAN 958A Class 1 level meter. The IP 65-rated case contains a lead-acid battery which operating time can be easily extended by connecting an external battery or solar panel, The system uses a low-noise, hermetically sealed tri-axial piezoelectric accelerometer. It provides broad-band vibration results such as RMS and Peak or Peak-Peak.

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 (optional alarm lamp). 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.

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.

  • Linearity range: 26dBA RMS divided by 140 dBA Peak (IEC 61672)
  • Meter modes: RMS, VDV, MTVV or Max, Peak, Peak-Peak, Vector, A (8), Dose, ELV, EAV
  • Detector constants: Fast, Slow, Impulse
  • Weighting: A, C, Z G
  • Detectors: Digital true RMS and RMQ detectors with Peak detection, resolution 0.1 dB
  • Battery life: 3 days (continuous modem) or 7 days (modem off)
