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)

High Quality & Easy of Use

	Simultaneous measurement of multiple parameters including PPV and VDV.
	Simultaneous tri-axial measurement. Compact and lightweight design.
	Data stored as CSV files on an SD card.
	User definable PPV vs Frequency comparator output supports DIN 4150: Part 3 and other frequency-dependent PPV building damage criteria.
	Flexible product configuration with waveform recording function and 1/3 octave band analysis function available as optional programs.
	Suitable for use in a live-to-web system (please contact us for further details).

Configuration Example for Remote Continuous Monitoring

Measurement results and data from the VM-56 can be accessed by computers,
tablets or smartphones via a network connection for continuous remote monitoring.

Option programs

Waveform Recording Program VX-56WR

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

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)
