are also growing in popularity.
" These devices can
be set so that an alarm is
sent to the control system
and at the same time an emergency
text can be sent to the field
tech or plant manager to notify them
of a problem with level, " he says. The
technology is also advancing to the
Figure 3. This ultrasonic technology
calculates tank level or volume while
the network or Internet communications
capability provides access to data from
virtually anywhere
ment independent of density, temperature
and dust and can also be used
with foam on the surface. The Pulscon
TLC is usable as a single measuring
cell or can be integrated into a Profibus
PA system.
Using the data
Similar to P+F, other device providers
are making advances in their technologies
that help deal with data, but
there's more than one way to skin the
data management cat. " The idea of
improving level measurement devices
around the information side of things
versus making the sensors themselves
more proficient at measuring level is
gaining in popularity, " says Jon Cox,
applications engineer with Automation
Products Group (Logan, Utah).
" As a result we are seeing more products
that provide information through
cell networks or the Internet or the
dispersion of information directly
through the sensor. "
His company, for example, recently
launched the LOE network/
Web enabled ultrasonic sensor. The
ultrasonic technology calculates tank
level or volume while the network- or
Internet-communications capability
provides access to data from virtually
anywhere. There are two programmable
solid-state relays for pump and
alarm point control and email, and
text message alerts are sent whenever
user-defined values are reached.
Adjustments can be made via built-in
web pages so that no programming
software is required.
Siemens' Boisvert adds that wireless
continuous-measurement devices
point where it can perform self diagnostics
via a sensor check or complete
check within the electronics or sensor
itself and send alerts or alarms, allowing
someone to make changes via
the control system rather than sending
out a technician to determine the
problem, Boisvert adds.

The link to progress
KMPT is now a part of ANDRITZ
Two international technology leaders have joined forces
With immediate effect, KMPT has become part of the ENVIRONMENT & PROCESS
business unit of the international ANDRITZ technology group. This is also to your
advantage because in the field of solids-and-liquids separation you will now be able
to benefit from the know-how and experience of both companies and their networks.
The tried-and-tested Krauss-Maffei centrifuges, filters, dryers and systems are now
being supplied by ANDRITZ KMPT.
