Portable vibration analyzers

Portable vibration analyzers

Aesse Misure has selected the company Adash for the marketing of predictive maintenance and condition monitoring systems.

Thanks to the competence of its staff, Aesse Misure accompanies the customer in all the necessary steps so that the instrument purchased brings real savings on maintenance costs.


Vibration, Noise, Thermography, Ultrasound

The new vibration analyzer developed by Adash, the A4500 VA5 Pro, is a portable tool for the diagnosis of rotating machine faults, which represents the state of the art of the systems available on the market.
The A4500 is equipped with 4 inputs able to simultaneously acquire the vibration signals coming from the sensors directly connected to the instrument or using the dynamic outputs of the vibration protection systems installed, as permanent monitoring systems, on large machines.
The input channels can be coupled in AC and DC and it is therefore possible, in case, for example, signals from proximity sensors are acquired, to detect not only the vibration, but also the "gap" and therefore the position of the shaft inside the bearing and, more generally, to acquire "slow" signals, referable to process parameters.
The instrument is also equipped with an input for the survey of the rotational regime and the machine phase.
The A4500 is equipped with a camera and can be equipped with a thermal imaging camera capable of capturing infrared images. The system is also able to perform noise analysis, both in the audible and ultrasound range. This peculiarity makes it suitable to be used also for the search of possible leaks inside the system.

Below is a list of available functions:

  • FFT Frequency Analysis
  • Order tracking
  • Envelope analysis for bearing diagnosis
  • ACMT analysis for bearing diagnosis on slow machines
  • Bode and Nyquist Analysis (Amplitude and Phase)
  • Orbits analysis
  • FRF and Bump Test for structural resonance research
  • Field balancer on 1 and 2 floors
  • Data-Collector with the help of the DDS2019 software
  • FASIT expert system for diagnostic support
  • ODS (operational deflection shape) with the help of ADS software
  • Octave and 1/3-octave noise analysis
  • Diagnosis of electric motors with MCSA analysis
  • Infrared thermographic diagnosis
  • Ultrasound microphone leak detection
  • Recording the original signal with post-processing capability

Fully configurable vibration analyzer and data collector

The A4300 VA3 Pro is the new vibration analyzer developed by Adash.
It is equipped with 2 inputs for vibration detection and 1 tachometer input. The second input can also be connected to a triaxial accelerometer, for the simultaneous acquisition of vibrations in the three spatial directions. The A4300 VA3 Pro is also equipped with an integrated strobe lamp for speed evaluation and an infrared sensor for temperature reading.

The instrument that is born, in its basic version, as a vibrometer, is equipped with an expert system - FASIT - able to automatically detect machine anomalies, such as unbalance, misalignment, mechanical loosening and bearing wear.

The A4300 VA3 Pro can be configured as desired by selecting the functions of interest from those listed below:

  •  FFT Frequency Analyzer
  • Data Collector (with the help of DDS2016 software)
  • Balancer on 1 / 2 floors
  • Recorder ( Function that allows you to store the original signal and process it later with the free PC analysis software
  • Transient analyzer (run-up / coast-down)


Portable analyzer for vibrational diagnostics on rotating machines. The instrument is extremely easy to use and provides precise and immediate indications of the condition of the examined machine.
The new DDS 2022 software allows the A4900 Vibrio M to be used as a data collector and thus create measurement patrols, download data automatically, and create customized reports.
