Siemens decides to HAUBER-Elektronik Type 663 to monitor sugar centrifuges
Intermittent Batch Process sugar centrifuges are usually
subjected to very high fluctuating loads / stresses as a
result of their cyclic operation with varying RPMs and
varying mash / slurry loads.
Improper mash / slurry inputs or even sugar deposits
in the centrifuge drum could, upon acceleration of the
centrifuge, lead to dangerous vibration levels resulting
in machine fatigue and damage.
Hence, such abnormal vibration levels must be instantly
recognized, so as to immediately shut-off the centrifuge,
in order to protect against machine damage & human harm.
In the process of modernizing the Intermittent Batch Process
sugar centrifuges Type ARO-1250 of the sugar refinery “Studen-Agrana“ in Bosnia Herzegovina, the complete
sensor, drive and automation systems – excluding the
DC motors - have been renewed by SIEMENS Erlangen in 2009.
Respectively for the important task of vibration monitoring,
SIEMENS chose HAUBER-Elektronik technology and
applied for this specific industrial process the compact
HAUBER-Elektronik vibration sensor Type 663.
This said vibration velocity sensor measures the absolute
bearing oscillation / mechanical vibration in accordance
with DIN ISO 10816 and in compliance with the SIL2 norm.
Its distinguishing characteristics of signal evaluation by
means of two integrated relays and an analogue output
that delivers a 4…20mA current proportional to the
measured value, as well as that both relay contacts are
free-programmable and serve as pre-alarm & main alarm,
make it an excellent choice for the vibration monitoring
of various centrifuge systems, as has already been
recognized and applied by SIEMENS Erlangen.
