New technologies for
centrifugal separation
This company's new centrifugal separator
for industrial fermentation applications
combines high separation area
with continuous solids discharge, making
it suitable for high-density broths.
Its hermetic design ensures very gentle
product handling, high separation efficiency
and low energy consumption.
The new centrifugal separator is suitable
for medium-sized batches. The company
has also developed new UniDisc
discs for its Culturefuge range (photo)
of centrifugal separators for harvesting
mammalian cells. The discs serve to
improve hygienic operations by minimizing
the number of deadlegs in a system.
The Unidisc design also makes it
possible to increase the total separation
area and improve separation efficiency,
says the company. Hall 4.0, Stand

Measure flow of conductive
materials with low pressure drop
The Flowmid series of electromagnetic
flowmeters (photo) is designed for measuring
conductive liquids in applications
where low pressure drop and infrequent
maintenance are required. There
are no moving parts or obstructing
elements in the instrument, allowing for
the passage of solids without retention.
The flowmeters can be assembled and
mounted in any position, provided that
the pipe is always full. Flowmid devices
provide good chemical resistance and
low power consumption. Available in
compact and remote versions, the devices
are configurable using a PC and
a USB cable using software provided
by this company. HART and Modbus
communication protocols are available
upon request. Hall 11.1, Stand A68 -

Instrumentation shelters with
a hybrid cooling system
This company is introducing a new
style of outdoor shelter for process
plant applications, the Peri Shelter
(photo), which features a cooling system
based on a hybrid combination of
unpowered passive and active powered
technologies. This shelter provides
a reliable operating environment
for control, analyzer and instrumentation
electronics. All system components
that are required for normal operation
are accessible via the building's
exterior.
Panel-mounting
enclosures
on the exterior provide access to electrical
connection and I/O termination
points, as well as cooling systems.
Touchscreen panels can also be fitted
to external walls, allowing operators
on the ground to monitor a control
element, such as a PLC, or make adjustments
to control programs locally
via an inspection door. The shelters
employ
glass-reinforced
polyester
(GRP) materials that are very insulating
and provide surface protection in
extreme environments, including those
with very high levels of ultraviolet (UV)
light and abrasion from sand or dust.

This dissolved-oxygen sensor
avoids bubble-induced errors
The OptaProbe (photo) is a smart optical
dissolved-oxygen (DO) sensor for
use in bioprocess applications with autoclave
or steam-in-place (SIP) requirements.
OptaProbe sensors feature this
company's DeflectorCap with a 45deg
angled sensing surface, which deflects
sparge bubbles in any insertion
orientation and SpargeSafe firmware,
which eliminates bubble errors. The
OptaProbe has a sophisticated, builtin
signal-filter system that recognizes
measurement noise caused by bubbles
and filters it out of the signal. This
significantly
increases measurement
precision in challenging bubble-filled
aeration environments. Measurement
errors caused by bubbles striking the
