Svan 958
Four Channels
Sound & Vibration Analyzer
Type 1
|
 |
OVERVIEW
The SVAN 958 is all digital, four channels 20 kHz signal analyser
including Type 1
sound level meter (meeting IEC 61672) and vibration meter (meeting ISO
8041).
It is an ideal choice for the "Human Vibration" (according to the ISO
2631-1,2&5
and ISO 5349-1&2 standards) and noise measurements in the occupational
health and safety monitoring tasks. All required weighting filters, along
with the
necessarry accessories for triaxial Whole-Body and triaxial Hand-Arm
vibration
measurements are available with this instrument.
Each of 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).
Three profiles allow parallel measurements with independently defined
filters and
RMS detector time constants in each sound channel. Each profile/channel
provides
"multidimensional" analysis of measured signal (like Leq, LMax, LMin, LPeak,
SPL, SEL in the case of sound measurements or RMS, Peak, Peak-Peak, VDV,
MTVV in the case of vibration measurements). Advanced time history logging,
in non-volatile 32 MB
internal memory, provides very powerful measurement capability. USB Memory
Stick extends this facility almost unlimitedly. Results can be easy
downloaded to
any PC using standard USB (or RS 232 or IrDA) interface and SvanPC+
software.
Using computational power of its digital signal processor the SVAN 958
instrument
can perform advanced frequency analysis simultaneously to the meter mode:
 | Real time four channels 1/1 octave or 1/3 octave analysis including
statistical calculations |
| Four channels FFT analysis including cross spectra |
| Sound intensity measurements. |
Reverberation Time measurements, noise dose meter and rotation speed
measurements are also available for SVAN 958.
The time domain signal recording on the external USB memory stick is also
available as an exceptional feature!
Fast USB 1.1 interface (12 MHz) creates real time link for the PC
"front-end"
application of the SVAN 958. Instrument can be fully remotely controlled.
Instrument is powered by four AA standard or rechargeable batteries
(separate
charger is required). The powering of the instrument from the External DC
power
source or USB interface is also provided.
Robust case and light weight design accomplish the exceptional features of
this
new generation instrument.
