An Overview: VIBRAS-7003 Vibration Measurement System
|The Vibras-7003 is the latest compact and modular
system with which all manner of man-made vibrations can be measured, such as from
blasting, pile driving, dynamic compaction, machinery, traffic, etc.
The system operates
on a principle using microcomputers and is built according to the standard DIN 45669. It
consists of the evaluation instrument and the sensors. Up to 12 digital sensors may be
connected to a single evaluation instrument. The system enables therefore simultaneous
monitoring of vibration at up to 12 independent locations, each in three orthogonal
directions, i.e. 36 channels.
The VIBRAS-7003 can
also be used for monitoring the levels of noise, which can be performed simultaneously
with vibration measurement.
Due to digital
transmission of data it is possible to have sensors located at considerable distances from
evaluation instrument, (e.g. a single digital sensor can be located at a distance of up to
1500 metres using a standard cable). However, if for a practical reason the cables cannot
be accommodated, some or all the sensors can be controlled by a radio signal. Figure 1 is a block diagram of the many connections and
interconnections which are possible.
The VIBRAS system is
designed for registration of single and/or continuous events. The system is ideal for
unattended monitoring of vibration over extended periods of time especially when used with
the remote control facility. During monitoring in the ramming or traffic mode the current
levels of vibration at each sensor are constantly displayed on LCD. Furthermore, the last
120 events stored in the memory can be reviewed at any time. The clear presentation of
measurement data in tabular and/or graphical formats on the printer allows initial
analysis on the spot, so that any necessary measures can be implemented immediately.
Vibration Measurement System provides the following:
WITH DIGITAL SENSORS AND A NOISE METER
The VIBRAS instruments are manufactured by WALESCH
Electronic GmbH of Switzerland.
