Ono Sokki Co., Ltd. (President: Yuji Okoshi) will announce its new product, the "Portable Vibration Meter VW-3100," on May 21, 2025. This product is a new type of vibration meter designed to perform a series of tasks required in equipment maintenance, inspection, and product testing, all with a single unit: "listening," "measuring," and "judging." The product is scheduled to be released in August 2025.

Portable Vibration Meter VW-3100
In the plant and manufacturing industries, equipment is aging, while the hurdles to new construction and replacement are high. Therefore, the importance of maintenance systems to keep existing equipment running for as long as possible is increasing. While vibration measurement has long been used for equipment diagnosis to monitor the condition of rotating machinery, stethoscopes are still widely used on-site. Judgment based on the intuition and experience of workers is highly valued, but this presents challenges such as individual variability and the difficulty of passing on know-how. This product, using our proprietary signal processing technology, extracts and quantifies abnormal components, thereby increasing the accuracy of detecting signs of abnormality. This allows for a shift from experience-based diagnosis to data-driven methods, and can be effectively used as a tool to improve the accuracy of judgments in design and maintenance departments and support the transfer of know-how.
Four key features of the new product
- V3 band allows simultaneous measurement and display of three vibration values (our proprietary function) / Enables accurate detection of abnormalities and improves work efficiency.
- The auditory function, which utilizes a variable bandpass filter, captures abnormal sounds and is used for sharing information with workers and for knowledge transfer.
- Recording is possible simultaneously with inspection (ORF/WAV) * / Post-analysis tools such as O-Solution can be used to perform a precise diagnosis.
- We offer a wide range of options to assist with on-site measurements and evaluations.
*Recording is an optional feature.
Target market and main applications
- Equipment diagnostics for rotating machinery in manufacturing sites across various industries.
- pass/fail judgment in production and inspection lines for motors, compressors, etc., in the automotive and home appliance industries.
Features
V3 band simultaneously measures and displays three vibration values.
The "V3 Band (Variable Three Band)" is a unique feature Ono Sokki that allows simultaneous measurement of different frequency bands using three variable bandpass filters. Each band allows selection of a physical quantity (acceleration, velocity, or displacement), and calculations such as RMS and peak values can be performed simultaneously. While conventional vibration meters have fixed frequency bands for each physical quantity, the "V3 Band" allows for flexible band setting according to abnormal vibrations. This enables more accurate extraction, listening, and quantitative detection and evaluation of abnormal sounds.
Auditory function using a variable bandpass filter
This product converts vibration signals acquired by a sensor into sound, allowing you to listen to them. By arbitrarily changing the frequency range with the V3 band, abnormal sounds can be detected more clearly, making it an effective alternative tool to a stethoscope.
It is also useful for identifying abnormal noises on-site, facilitating information sharing among workers, and supporting the transfer of technical skills.
Recording function and comparison function (optional: VW-0320)
Recording (ORF/WAV) can be done immediately while measuring and inspecting. The data can then be taken back to the office and used with post-analysis tools such as O-Solution for detailed analysis and listening tests, leading to a more precise diagnosis. Furthermore, the ability to switch between the three recorded data sets and the vibration sounds measured on-site makes it easier to determine the presence or absence of abnormalities.
A wide range of options to assist with on-site measurement and evaluation.
Equalizing function VW-0310
The vibration sound can be increased or decreased in 1/1 octave band increments. This allows you to replicate the listening habits of experienced musicians and share their key nuances.
Filter extension VW-0330
In addition to the standard built-in bandpass filter, you can select even finer frequency ranges.
ISO evaluation and judgment function VW-0340
It supports the evaluation of vibration severity, an index indicating the intensity of vibration in rotating machinery. Equipped with a filter compliant with ISO 2954:2012, it enables A/B/C/D evaluation according to ISO 20816-3:2022, 20816-1:2016, etc. It is also possible to set arbitrary thresholds to match the characteristics of the machine.
Vibration diagnostic assist tool VW-0350/VW-0360
This is a PC application function that supports measurement and data management for this product. By registering measurement conditions and equipment information in advance and sending it to the main unit, it eliminates the need to set conditions for each machine on-site, enabling efficient inspections. In addition, data acquired by the main unit can be imported to the PC, and trend management graphs and vibration sound playback can be performed. This supports the establishment of a system that allows for equipment diagnosis using several machines and accurate maintenance decisions through regular trend management.
