ADASH A4900 Vibrio M – A Compact Vibration Measurement Solution for Condition Monitoring

In Predictive Maintenance, regular vibration data collection helps technicians monitor equipment condition and identify early signs of abnormal operation.

The ADASH A4900 Vibrio M is designed as an all-in-one solution that combines a Vibration Meter, Analyzer, and Data Collector in a compact handheld device. It provides a range of essential vibration measurements together with tools for machine condition analysis and diagnostics.

1. Multi-Parameter Vibration Measurement

The A4900 Vibrio M supports various vibration measurements and data formats, including:

• Overall Values – RMS and Peak
• Velocity
• Acceleration
• Displacement
• FFT Spectrum
• Time Waveform
• Frequency Bands
• Demodulation / Envelope

Velocity can be used to evaluate overall machine vibration, while acceleration is particularly useful for monitoring vibration associated with bearing condition. Automatic speed detection is also available as part of the Overall Values measurements.

2. FFT Spectrum – Vibration Spectrum Analysis

The A4900 Vibrio M features FFT Spectrum Analysis, allowing technicians to examine the frequency components of vibration signals.

The device can identify up to 3 maximum spectral peaks, helping users quickly identify the most prominent vibration components during machine inspection.

3. Time Waveform – Time-Domain Signal Analysis

The Time Waveform function allows users to observe vibration signals in the time domain. This can be particularly useful for examining impacts, impulses, and other vibration patterns associated with bearing condition.

The Vibrio M also supports Demodulation / Envelope Analysis, providing additional information for analyzing characteristic vibration signals.

4. FASIT – Fault Source Identification

One of the key features of the Vibrio M is FASIT – Fault Source Identification Tool.

FASIT supports the identification of common machine faults, including:

• Unbalance
• Looseness
• Misalignment
• Bearing Condition

This function makes field inspections more intuitive and provides additional support for routine Condition Monitoring activities.

5. Non-Contact Temperature Measurement

In addition to vibration measurement, the A4900 Vibrio M features an integrated IR thermometer for non-contact temperature measurement.

With a measurement range of -70°C to +380°C, the device can be used for quick temperature checks of machine components during inspection and maintenance activities.

6. Data Collection and Monitoring

The Vibrio M features internal memory for storing measurement data and supports data transfer via USB-C.

The device is supplied with a free version of DDS – Digital Diagnostics System, allowing users to collect measurement data with the Vibrio M, transfer the data to the software, and monitor machine vibration trends over time.

This provides a foundation for implementing Condition Monitoring programs and supporting the development of Predictive Maintenance strategies.

7. Compact Design for Field Inspection

The A4900 Vibrio M is designed for practical use in the field and routine machine inspections. Key features include:

• Durable aluminum housing with rubber protection
• Outdoor-readable TFT color display
• Integrated LED light
• LED stroboscope
• Stethoscope for listening to machine and bearing noise
• USB-C connectivity
• Li-Ion battery with up to 16 hours of continuous operation
• Approx. 380 g weight, excluding cable, sensor, and magnet
• IP54 protection rating

8. A Practical Solution for Predictive Maintenance

With its combination of vibration measurement → signal analysis → fault identification → data storage and trend monitoring, the ADASH A4900 Vibrio M can support a wide range of maintenance and machine inspection activities, including:

• Condition Monitoring
• Predictive Maintenance
• Preventive Maintenance
• Machine Diagnostics
• Vibration Measurement
• Rotating Machinery Inspection

The Vibrio M is suitable for routine inspection of rotating machinery such as motors, pumps, fans, gearboxes, compressors, and other industrial equipment.
