ADASH Ltd. Adash 4700 – Vibration Recorder
A4700 - Vibration Recorder - 61171 Device description:
The ADASH 4700- Vibration Recorder is designed for measurement in inaccessible places. It has been developed as individual unit with its own built-in power supply. The instrument can be mounted directly to a machine by bolts or other fixtures. This feature enables the 4700 to take measurements from points with difficult or no access (e.g. moving parts of machines, dangerous areas, etc.). It is possible to measure a standard time signal (40kHz sampling freq.) or a long-duration trend of wideband static values (True RMS, True Peak or Envelope modulation). The setup of instrument is created on a PC and is saved as a file to the memory card. The measurement configuration in the memory card is automatically read after the 4700 is switched on. The 4700 will continue to take the required data automatically and free of human operation until either the battery is discharged, the memory is full or it is switched off by the user. Standard flash card (MMC or RS-MMS) with capacity from 128MB to 1GB is used for data storage. The continuous measurement of a time signal is saving approx. 10MB of data per minute. The time capacity of memory can therefore be from 12 to 100 minutes. Static, trend, measurements have lower memory consumption, so the time capacity of the memory is much larger. After the measurements are completed, the data is transferred to PC (by standard memory reader/writer). Data analysis can then be made by other software, e.g. Adash DDS, SigView, etc. The internal power supply (rechargeable battery) enables up to 8 hours of continuous measurement. By using an external power supply the monitoring time is only limited by memory size.
