Svan 957
Sound & Vibration Analyser
Type 1
|
 |
OVERVIEW
The SVAN 957 is all digital, Type 1 sound & vibration level meter along
with analyser.
Instrument is intended to general acoustic and vibration measurements,
environmental
monitoring, occupational health and safety monitoring.
Three acoustic or vibration profiles allow parallel measurements with
independently
defined filters and RMS detector time constants. Each profile provides
significant number
of results (e.g. for sound: Leq, LMax, LMin, LPeak, Spl, SEL or RMS, PEAK,
VDV, MTVV
in the case of vibration measurements). Advanced time history logging for
each profile
provides complete information about measured signal in non-volatile 32 MB
internal
memory or external USB Memory Stick and can be easy downloaded to any PC
using USB
interface and SvanPC+ software.
All required weighting filters (e.g.: A, C, Wk, Wc, Wh) including the latest
ISO 2631-1&2
standard are available with this instrument. RMQ detector enables direct
measurement
of the Vibration Dose Value (VDV). Using computational power of its digital
signal processor
the SVAN 957 instrument can, simultaneously to the meter mode, perform real
time
1/1 or 1/3 octave analysis including statistical calculations, acoustic dose
measurements,
FFT analysis and Reverberation Time measurements. The time history logging
of 1/1 octave, 1/3 octave and FFT analysis is provided. The time domain
signal recording
on the external USB memory stick is also available.
Fast USB 1.1 interface (12 MHz) creates real time link for the PC
“front-end” application
of the SVAN 957 instrument. Instrument can be remotely controlled and
measurement
results can be downloaded to a PC using the RS 232 or IrDA interfaces.
Instrument is powered from four AA standard or rechargeable batteries
(separate charger is required). The External DC power source or
USB interface can be also used for powering the instrument.
Robust, hand held case and light weight design accomplish
the exceptional features of this new unusual instrument.
