SVAN 956
Vibration Meter & Analyzer
 |
OVERVIEW
The SVAN 956 is all
digital, Type 1 vibration level meter along with analyser. Instrument is
intended to general vibration measurements, machinery condition monitoring,
occupational health and safety monitoring. It can be used by consultants,
maintenance services and industry R&D departments etc.
Instrument provides parallel acceleration, velocity and displacement
measurements. Three vibration profiles allow parallel measurements with
independently defined filters and RMS detector time constants. Each profile
provides significant number
of results (like RMS, Peak, Peak-Peak, VDV, MTVV or MAX). 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.: Wk , Wc , Wh for Human Vibration
measurements or VelMF for machine diagnostic measurements) including the
latest ISO 2631-1&2 and ISO 10816 standards are available with this
instrument. RMQ detector enables direct measurement of the Vibration Dose
Value (VDV).
For machine condition maintaining application the SVAN 956 instrument
provides programmable "route" of the measuring points.
Using computational power of its digital signal processor the SVAN 956
instrument can additionally perform real time FFT analysis, 1/1 octave
analysis, 1/3 octave analysis, balancing of rotation mass and sophisticated
enveloping analysis.
The SVAN 956 offers also RPM measurement with Monarch laser tachometer
parallel to the vibration measurement.
The time domain signal recording on the external USB memory stick is
available.
The instrument can be controlled and the measurement results can be also
downloaded to any PC using the RS 232 or IrDA interfaces.
Instrument is powered from 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.
