Vibration measuring systems

Data Acquisition Analysis System Wave Stocker (VM-0330 /16)

For waveform data acquisition and analysis
By simultaneous sampling measurement of up to 16 channels, data collection and judgement is possible. It can be widely used for site measurement, monitoring and developmental study.
Data Acquisition Analysis System Wave Stocker (VM-0330 /16)

Features

■ Compact and light weight
■ Data transfer by USB 2.0
■ Easy to operate
■ Long term continuous data acquisition is possible

Functions

  • ■ Waveform acquisition

    Waveforms of up to 16 channels are displayed and data observation (as waveform only, FFT only, waveform plus FFT) is possible during measurement is proceeding. You can operate various setup, halt and stop etc. instinctively just like a home video recorder.

    Waveform acquisition

  • ■ Analysis function

    Data is saved as text files after various analysis such as inter-channel calculation, filtering, waveform edit, FFT (spectrum) analysis, differentiation, integration, and DC removal etc. The data is available with the commercialized software as Excel.

    Analysis function

  • Transportation vibration time history waveform screen
  • Swept original wave forms screen
  • Resonance graph screen

System Composition

Data aquisition and analysis system (Wave Stocker) is composed of Simultaneous sampling unit (VM-0330R/16), Charge amplifier (VM-1980/3) and Data record software (DS-0330).

Analysis Tool Function
Analysis 000 Data Recording Tool (standard)
Concept
This is a data saving tool to make a pre-processing as filing the simultanous sampling data from 16 ch A / D unit, waveform monitoring, regeneration, data extraction for analysis. It is also possible to monitor the original waveforms or FFT analysis in real time of 16 channels. This is an essential item to use other analysis tools.
