Svantek SV 958A
Four Channels Sound & Vibration Meter

The standard kit includes SVAN 958A 4-channel sound & vibration level meter with an USB cable, set of 4x AA batteries, SC 61 TNC/BNC adapter and the user manual on a pendrive disk. Each SVAN 958A has its factory calibration certificate and a 36-MONTH WARRANTY upon product registration. The standard kit also includes license for PC software.

Svantek SV 958A Four Channels Sound & Vibration Meter

SVAN 958A Class 1 Four-channel Sound & Vibration Analyser is dedicated for all applications that require simultaneous class 1 sound and vibration assessment. Each of four input channels can be independently configured for sound or vibration detection with different filters and RMS detector time constants giving users an enormous measurement flexibility. The real advantage of SVAN 958A is the capability to perform advanced analysis simultaneously to the level meter mode. In practise this allows the user to obtain broad-band results such as Leq, RMS, LMax, LMin, LPeak together with four-channel analysis like FFT or octave band analysis.

List of available analyser functions includes FFT, 1/1 or 1/3 octave, cross spectra, sound intensity, RT 60 and more. The 4-channel time-domain signal recording to .wav format is available as well as an exceptional feature! All measurement results are stored in non-volatile 32 MB internal memory or USB memory stick and can be easily downloaded to a PC with SvanPC++ software. SVAN 958A with RS 232 interface (SV 55) can be offered with GPRS modem or LAN & WLAN connection module. Together with SvanPC++_RC remote communication software, these interfaces provide easy remote access to instrument settings & data over Internet and local area network. Instrument is powered from four AA standard or rechargeable batteries as well as from the external DC power source or USB interface. Robust case and light weight design accomplish the exceptional features of this new generation instrument.

 

SVAN958A Four Channels Meter is an unique instrument offering 20 kHz-band sound & vibration analysis. It is a perfect choice for all applications that require simultaneous Class 1 noise measurements & triaxial vibration assessment. Each of four input channels can be independently configured for sound or vibration mode with different filters and RMS detector time constants giving users an enormous measurement flexibility.

 

Building and ground vibration

DIN 4150-3 and VC curves measurements

The most recognizable standards for structure vibration measurements are ISO 4866, British BS 7385-2, and German DIN 4150-3. All these three standards use Peak Particle Velocity (PPV) method and FFT to define the Dominant Frequency. The BUILDING VIBRATION mode in SVAN 958A offers simultaneous VELOCITY and ACCELERATION measurements with the automatic indication of a DOMINANT FREQUENCY.
