Four Channel Sound & Vibration Analyser- SVAN 958A
Stockcode:
SVAN 958A Four Channels Sound and Vibration Analyser with time domain signal recording. It is a fully digital, four channels 20 kHz signal analyser including Type 1 sound level meter (meeting IEC 61672) and vibration meter (meeting ISO 8041:2005).
Simultaneously to the meter mode, SVAN 958A can perform advanced frequency analysis including 1/1 or 1/3 octave analysis, FFT analysis including cross spectra’s and sound intensity measurements. Reverberation Time measurements, noise dose meter and rotation speed measurements are also available. Moreover, SVAN 958A has an exceptional feature of time domain signal recording to the USB memory stick.
SVAN 958A is an ideal choice for “Human Vibration” (according to the ISO 2631-1,2&5 and ISO 5349-1&2 standards). It is offered with all required weighting filters and comprehensive range of equipment for measuring hand-arm and whole-body vibration.
SVAN 958A uniquely does the analysis in four channels. Each of the four channels can work simultaneously with independently configured input (transducer type), filters and RMS detector time constants (e.g. simultaneous three axis measurement of the Whole-Body vibration and noise dose).
Recently SVAN 958A has been improved by implementation of the special KB filter for building vibration measurements meeting the DIN 45669-1 standard (DIN 4150 standard refers to this filter).
SVAN 958A can also perform noise measurement with accuracy of Type 1. Thanks to its four channels it can measure sound by the use of four independent microphones in the same time. What is more, in sound meter mode, each channel uses three independently defined profiles which means that SVAN 958 can perform “multidimensional” analysis of measured signal in every of four channels. In practice it gives a user the possibility to obtain Leq, LMax, LMin, LPeak, Spl, SEL with different weighing filters in the same time.
