VM-56 | Tri-axial Groundborne Vibration Meter


Simultaneous PPV, VDV, Dominant Frequency & Displacement

The VM-56 is a groundborne vibration meter capable of simultaneously calculating the measurement quantities defined by
DIN 45669-1, ISO 8041 and other national measurement standards. Like other Rion products, it is characterized by excellent
build-quality and exceptional ease of use. It is suitable for a wide range of applications including attended measurements,
unattended surveys and live-to-web monitoring.

Applicable standards

・DIN 45669-1 : 2010-09

   (Measurement of vibration immission -Part 1:Vibration meters – Requirements and tests)

 *Measurement range, measurement frequency range only

・ISO 8041 : 2005, ISO 8041-1 : 2017

   (Human response to vibration – Measuring instrumentation)

Option programs

Waveform Recording Program VX-56WR

vm-56 Allows recording vibration waveforms on SD card as WAV files.

The recording process is carried out simultaneously with the standard VM-56 functions.

 *2 kHz sampling with 24 bit or 16 bit can be selected

Max. recording time (at 16 bit)

・512MB:Approx. 6 hours

・2GB:Approx. 27 hours

・32GB:Approx. 470 hours

1/3 Octave Band Analysis Program VX-56RT Coming soon

vm-56 Enables measurement and logging of 1/3 octave acceleration levels simultaneously with broadband
parameters (e.g. PPV, dominant frequency, VDV, MTVV). Can be used concurrently with VX-56WR.

 *User definable weighting -enables compliance with ISO 2631-2:1989/RD1367


Software / Report Creation

Waveform Analysis software for Groundborne Vibration AS-70GV Coming soon

Allows use of WAV files recorded with VM-56 + VX-56WR for graph display, level processing,
frequency analysis (octave band analysis / FFT analysis), recalculation (PPV, KB, VDV) , and file output.


Excel macro for report output(free of charge)

Facilitates the creation of reports from measurement data.
