SVAN 956
Advance Vibration Analyser with time domain signal recording

Vibration Meter & FFT Analyser with time domain signal recording

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 allows 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 (option) and can be easy downloaded to any PC using USB interface and SvanPC+ software.

 

  

SVAN 956 ORDERING INFORMATION

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 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 1/1 octave analysis, 1/3 octave analysis, FFT analysis, balancing of rotation mass and sophisticated enveloping analysis (all functions are available as an option). SVAN 956 offers also RPM measurement (option) parallel to the vibration measurement with Monarch laser tachometer.

The time domain signal recording on the external USB memory stick is also available as an option.

The measurement results can be also downloaded to any PC using the RS 232 interface (option) or IrDA interface (option).

Instrument is powered from four AA standard or rechargeable NiMH batteries (separate charger is required). The powering of the instrument from the External DC power source or USB interface is also provided.

Robust and light weight design accomplishes the exceptional features of this new generation instrument.
