curate level control and significantly
reduces process disturbance, resulting
in more stable froth conditions
and therefore improvements
in the flotation cell's metallurgical
performance. CellStation has
plug-and-play connectivity with the
FrothSense sensor system, which
measures the essential properties
of froth, including speed, direction,
bubble size, stability and color, and
provides statistical data related to
these variables. - Outotec Oyj,

A level transmitter for powders
and dusty atmospheres
The Optiwave 6500C (photo) is a
radar level transmitter that delivers
continuous measurement in silos,
hoppers and containers. The Optiwave
6500C is an optimal product
for bulk storage in the mining,
minerals, chemicals, power, paper,
food and beverage industries. The
radar offers several advanced technological
features, including an 80GHz
(FMCW) bandwidth radar and
a 70-mm lens antenna, making it
suitable for environments with lowreflective
media. With a measuring
range extending over 100 m, the
Optiwave 6500C handles uneven
surfaces or tanks with obstacles.
Other advanced features include
a large backlit LCD screen with a
four-button keypad, ensuring flexibility
for different radar usage. -

Accurate level detection -
regardless of media
The CleverLevel PL20 level
switches (photo) utilize frequency
sweep technology, which ensures
accuracy and consistency regardless
of the type of process medium
being measured. The switches provide
reliable limit detection without
the need for parameterization to a
specific medium, so regardless of
whether the process medium is liquid,
paste-like, sticky or granular,
the CleverLevel PL20 recognizes
them. As a consequence, they are
ideal for industrial and hygienic applications,
because the switches
also distinguish foam and liquid as
well as detecting separating layers.
The device is approved to both 3A
and EHEDG standards. - Baumer

GWR transmitter operates in
harsh processing conditions
The new Eclipse Model 700 guided
wave radar (GWR) transmitter is designed
to be virtually unaffected by
changing media conditions, including
turbulence, foaming, boiling
and flashing. Proactive diagnostics,
like the Model 700's buildup
detection feature, minimize
maintenance costs by allowing
engineers to proactively schedule
shutdowns and maximize uptime.
Eclipse GWR solutions, including
the new Model 700, are designed
to handle any level of complexity
and are equipped for overfill protection
through the probe design,
which allows for level measurement
across the entire probe length with
a smaller dead zone than alternatives.
The instrument has a reference
accuracy of ±0.1 in. or 0.1%
of the probe length, whichever is
larger. - Magnetrol, Aurora, Ill.

Level switches for
packed powder applications
The GJ level switch (photo) can operate
as high or low point level indicators
for bulk solids that tend to
pack or bridge easily. The GJ Detector
operates successfully with consistent
results on chemical powders,
minerals and many other granulated
materials. These level switches measure
dry bulk solids ranging from less
than 15.0 to greater than 60 lb/ft3.
The level detectors are factory calibrated
and do not require any field
calibration before installation. There
are no moving parts and no gaskets
or seals to deteriorate, providing
superior performance in dusty
environments. The GJ level detector
relies on mechanical oscillations to
determine if the probe is covered or
uncovered. When combined with the
EC-501A Control Unit, signals from
the detector operates a single-pole
double-throw relay within the control
unit and users can actuate process
control equipment, level alarms or
indicator lights. - Automation Products,
