Blasting: Vibration Meters


Despite modern technology, vibrations are inevitable during construction, blasting or demolition.  In order to avoid unintentional damage and not to endanger people, those vibrations need to be measured and evaluated.
ZEB vibration meters offer great performance in all areas for a great price.
Measuring and analysis are possible for both transient vibrations
(e.g. during blasting) and lasting vibrations (e.g. traffic).
 
 

ZEB/SM-3E

This vibration meter are a good option that will help any company related to these industries to keep track of the vibration levels reached in any construction or blasting operation.

ZEB/SM-3C

The three-channel vibration meter meets the standard requirements in all of the highest accuracy class and is thus fully suitable for self-monitoring, vibration analysis as well as to preserve evidence.
No. 2740


 

VibraZEB VM-7D+

The vibration meter ZEB/VM-7D is available in two variants:
- a BASIC version with 3 channels (can be subsequently extended to 6 channels)
- a PRO version with 6 channels

By the data transfer to an external USB-Disk the data can be recorded without a computer.
Data can be downloaded and setup commands can be uploaded directly or remotely by modem (optional). Recorded vibrations can be documented directly at the measuring point by a printer (optional).
The graphical presentation of the vibration data as well as a clear
recording of the measuring data is possible by the delivered software (from WIN NT/XP).
The functioning of the entire measuring system is documented
by an automatic review before each measurement.
- Friendly and easy functionality
- Designed to work under rough conditions
- Pre- adjustable recording parameter
- Documentation of self-test
- Remote access / WEB and FTP servers (optional)
- Record print for documentation (optional)
- Channel for sound microphone (optional)
- Main supply and battery operated (approx. 20 hours)
- Measuring data evaluation and recording with the easy to use software
- Reports: Record, Analysis FFT
- Regressions anaysis (charge/distance tabl)
No. 2780 (BASIC version with 3 channels)
No. 2790 (PRO version with 6 channels)                         more informations
