Profound Vibration Monitoring
Profound VIBRA geophone
The Profound geophone for the VIBRA range
has been designed for high-performance
vibration monitoring.
Advanced mounting
The ball joint in combination with the wall
bracket facilitates precise orientation of the
geophone in the correct x-, y- or z-direction,
as well as enabling fine tuning of the vial.
Digital ID
The geophone has an electronic datasheet,
which also includes the serial number.
Therefore, the source of measurement data
can always be traced.
High-performance
Besides continuously monitoring the x-, y-
and z-direction, the VIBRA also automatically
corrects the measurement data for the
individual sensitivity of each geophone
channel.
This
guarantees
measurements and performance.
Plus
The VIBRA geophone in combination with the
+
VIBRA
offers the following extras:
Digital measurement of the geophone's
-
inclination, assuring that measurements
are
carried
out
positioned geophone.
-
Based on data from the electronic
datasheet, the VIBRA
the sensitivity, but also the resonance
frequency and the quality factor with the
help of digital correction filters.
More information about the Profound VIBRA
range can be found in the technical
specifications of the VIBRA.
