- Rion General-Purpose Vibration Meter VM-82A
Three measurement modes: acceleration, velocity and displacement Internal memory stores up to 1000 data
The general-purpose vibration meter VM-82A is designed mainly for maintenance and inspection of industrial machinery, with particular emphasis on rotational machinery. Acceleration, velocity, and displacement can be easily measured using a suitable frequency range, allowing comprehensive and precise evaluation of machine vibrations.

Use
Wide range of possible applications
Using the standard accelerometer PV-57ｴ supplied with the unit, the measurement range of the VM-82A is as indicated by the Orange colored section in the table. Selecting a different accelerometer makes it possible to perform a wide range of other measurements.
Accelerometer sensitivity, measurement full-scale range, and frequency range can be set to achieve the measurement configurations shown in the table.
| Measurement mode |
Accelerometer sensitivity mV/(m/s2) (pC/(m/s2)) |
Measurement full-scale range |
Frequency range |
| ACC (m/s2) Acceleration | 0.1 to 0.99 | 10 to 10 000 | 3 Hz to 1 kHz, 3 Hz to 5 kHz, 3 Hz to 20 kHz, 1 Hz to 100 Hz |
| 1.0 to 9.9 | 1 to 1 000 | ||
| 10 to 99 | 0.1 to 100 | ||
| VEL (mm/s) Velocity | 0.1 to 0.99 | 100 to 10 000 | 3 Hz to 1 kHz ＊10 Hz to 1 kHz |
| 1.0 to 9.9 | 10 to 1 000 | ||
| 10 to 99 | 1 to 100 | ||
| DISP (mm) Displacement |
0.1 to 0.99 | 1 to 1 000 | 3 Hz to 500 Hz, 10 Hz to 500 Hz |
| 1.0 to 9.9 | 0.1 to 100 | ||
| 10 to 99 | 0.01 to 10 |
＊Electrical characteristics for velocity from 10 Hz to 1 kHz are compliant with the frequency range requirements of JIS B 0907 “Mechanical vibration of rotating and reciprocating machinery – Requirements for instruments for measuring vibration severity”.
Data store capability
The internal memory of the VM-82A can hold up to 1 000 data. In recall mode, any of the stored data can be easily redisplayed by specifying the desired address. Stored data can also be transferred to a computer. ＊Bar graph indication and remaining battery capacity indication are not stored. (Transfer software can be downloaded free of charge from the Rion web site.)
Easy-to-read display
The large LCD panel displays the bar graph meter and numeric reading at the same time, making it easy to visually evaluate any changes immediately. The display also shows the frequency range setting and other useful information. Backlighting can be turned on if required, allowing use of the unit also in dark locations. In case of overload, the indication “OVER” appears, and the entire display color changes to red.
