Portable Vibration Meter
NEW
VW-3100

The VW-3100 is a Portable Vibration Meter that realizes "listening", "measuring", and "judging" necessary for on-site vibration measurement in one device.
It solves problems with vibration sensing technology and signal processing technology provided by Ono Sokki, a manufacturer of measuring instruments.

Four points of the VW-3100

1. Never miss machine abnormalities
Simultaneous display of acceleration, speed, and displacement.
Prevents oversight and maximizes inspection efficiency.

2. Be the "ear" of the expert
Accurately identify abnormal sounds with a variable filter.
Helps in the transmission of diagnostic techniques using a stethoscope.

3. Bring back the "evidence" from the field
Simultaneously perform vibration measurement and recording.
Enables precise diagnosis in the office.

4. Supports ISO evaluation, route inspection, and trend management
Strongly assists vibration measurement with various functions such as ISO 20816 evaluation and trend management.

List of Functions

Standard Functions

Vibrometer mode

In addition to four types of display modes (Single, Triple, Trend, List), it is equipped with a listening function and a band-pass filter as standard.

  • Vibrometer mode

Measure three vibration values simultaneously.

Issue :
Despite regular inspections, the machines still break down.
The machine's malfunction hasn't been detected.

Solution :
To identify machine malfunctions, it's necessary to measure three vibration values (acceleration, velocity, and displacement). These values can be calculated and displayed simultaneously using the V3 band. This allows for accurate identification of abnormalities and improves work efficiency.

Can extract abnormal sounds and signs of deterioration.

Issue :
I can't tell which one is the strange noise.
There is no difference in vibration values between normal and abnormal conditions.

Solution :
A variable bandpass filter allows you to freely set the frequency range and extract only specific frequency bands.

Can hear the vibrating sound.

Issue :
The experience of skilled professionals and the sounds heard with a stethoscope
It cannot be shared or passed on to other workers.

Solution :
The sensor signal can be converted into sound and listened to. By narrowing the frequency range with a variable filter, it becomes easier to detect abnormal noises.
It can also be used as a tool to listen to "vibrational sounds" instead of a stethoscope.

Easily switch between four measurement screens.

By changing perspectives in measurement, understanding of phenomena advances, leading to increased measurement efficiency.

  • Single: Check vibration value, rotation speed, and equipment name.

  • Trend: Understanding the fluctuations of vibration values.

  • Triple: simultaneously measuring three vibration values.

  • List: Grasp measurement values at once.

  • Easily switch between four measurement screens.

Optional Functions

VW-0310 Equalizing Function (options)
VW-0310 Equalizing Function (options)

Issue :
It's difficult to distinguish between different sounds from a variety of other sounds, like a skilled professional can.

Solution :
The vibration sound can be increased or decreased in 1/1 octave band increments. By emphasizing unwanted sounds and reducing them, you can recreate the "hearing" of an expert and share key nuances.

VW-0320 Recording and Comparison Function (options)
Just press REC→START for detailed analysis in the office.
Just press REC→START for detailed analysis in the office.
Recording function

Issue :
Bringing a data recorder is a hassle. Gathering people on-site to check for unusual noises is also troublesome.

Solution :
You can record while taking measurements and performing inspections. You can then take the recordings back to the office, listen to the vibration sounds again, and perform detailed analysis using software like O-Solution. It can also be used for technology transfer.

Register recorded data

Comparison Function

Issue :
I can't tell if the vibration sound has changed.
I want to compare it to the sound when an abnormality occurs.

Solution :
You can switch between vibration sounds measured on-site and pre-recorded vibration sounds and compare them in real time.
Furthermore, using the V3 band makes it easier to determine whether or not there is an abnormality.

VW-0330 Filter Expansion Function (options)
HPF/LPF cutoff frequency [Hz] (the shaded area is expanded)
HPF/LPF cutoff frequency [Hz] (the shaded area is expanded)

Issue :
We want to accurately capture the abnormal phenomena.
I want to take measurements without being affected by noise.

Solution :
In addition to the standard bandpass filter, you can select even finer frequency ranges.

VW-0340 ISO Evaluation and Judgment Function (options)
You can immediately tell if the threshold has been exceeded.
You can immediately tell if the threshold has been exceeded.

Issue :
I want to move away from maintenance that relies solely on experience.
I want to make appropriate decisions while monitoring vibration values.

Solution :
You can choose between absolute value evaluation and relative value evaluation as your evaluation method.
The equipment's condition can be assessed using evaluation criteria that comply with ISO and JIS standards.

Vibration Diagnosis Assist Tool

VW-0360 Vibration Diagnosis Assist Tool (options)

This is software that manages the measurement conditions and acquired data of the vibration meter.
By creating measurement conditions and evaluation criteria on the software and sending them to the Portable Vibration Meter, the efficiency of inspection work can be improved. Furthermore, by smoothly visualizing the trends of vibration values and comparing them with evaluation criteria, it leads to the efficiency of maintenance work.
