Vibration Meter

The VM-82A multifunctional vibration meter is primarily designed for the maintenance and testing of industrial machinery, with a particular focus on rotating machinery. Acceleration, velocity, and displacement can be easily measured using the appropriate frequency range, allowing for comprehensive and accurate assessment of the machine's vibrations.

Specification

- Frequency Range of Rion VM-82A

• Acceleration: 3 Hz to 1 kHz, 3 Hz to 5 kHz, 1 Hz to 100 Hz, 3 Hz to 20 kHz
• Velocity: 10 Hz to 1 kHz, 3 Hz to 1 kHz
• Displacement: 10 Hz to 500 Hz, 3 Hz to 500 Hz

The values representing the measurement range are subject to approximately 10% attenuation due to high-pass or low-pass filter action. Electrical characteristics for velocity from 10 Hz to 1 kHz comply with the frequency range requirements of JIS B 0907 "Mechanical Vibration of Rotating and Reciprocating Machinery – Requirements for Instruments for Measuring Vibration Severity."
