Innovations
made of numerous different components
that are often not exactly matched to each
other and require a lot of space and installation effort.
Schubert & Salzer Control Systems
has now developed an out-of-the-box
solution (FIG. 2) for this specific application. In this case, the cooling and lubrication of the shaft seals in centrifugal
pumps with the operating fluid is controlled via a compact manifold. The adjustable 7010 angle-seat shutoff valve integrated into the block allows a flowrate
of 10 l/hr-50 l/hr to be set.
When the pump is started, the pneumatic valve opens simultaneously, so that
cooling and lubrication are ensured immediately. The liquid sensor integrated
in the manifold permanently checks that
coolant always flows when the pump is
running. If there is no cooling, the pump
is switched off to prevent damage to the
shaft seal and to prevent it from getting
stuck. The switch-off and switch-on
functions can be carried out via the pump
control or can be taken over by a PLC.
As a complete solution, the new system is not only more compact than solutions commonly used in industry, but
also significantly reduces installation and
maintenance costs.
The manifold is suitable for all centrifugal pumps within the specified performance range, and can be extended with
manometer connections, pressure and
temperature sensors, etc. Further options
and intelligent, specific, modular solutions are also possible.

Multi-gas detector
Concentrations of hazardous substances in the ambient air at the workplace
should not exceed specified limit values.
Monitoring these sometimes very low values is a demanding task. The focus of the
Dräger X- act 7000, in combination with
the Dräger MicroTubes for different gases
and vapors, is to measure carcinogenic
and toxic substances in the lower-ppb
range. The range of gases to be measured
is being constantly expanded. The measurement-sensitive system of the X-act
7000 is based on colorimetric chemical
sensor technology and measures even the
lowest ppb concentrations. It can replace
conventional laboratory analysis and delivers exact reliable results directly onsite.
False-positive measurement results and
false alarms can be largely reduced.
The RFID tags applied to the Dräger
MicroTubes contain all the calibration
data that is valid for the typical period of
use of one year. Complex functional tests
and manual calibration procedures are no
longer necessary. All possible temperature and humidity influences are already
considered during factory calibration.
The analyzer is explosion-proof and certified in accordance with ATEX/IECEx for
zone 0 and CSA Class I, Zone 0. In addition, the system is IP54 protected against
dust and splash water. It also meets the
requirements of electromagnetic compatibility according to EN 61326-1.
After an automatic self-test, the X-act
7000 analysis system is immediately ready
for use. The user controls the measurement task via the 3-button operation unit
and the 2.4-in. color display. The measurement result, location and time can be
stored in the internal data logger and read
out with the Dräger CC Vision software.
Power is supplied by five easily replaceable
batteries. The battery capacity is sufficient
for more than 10 hr of measuring and is
indicated on the display. The Dräger X-act
7000 can be used with the Dräger X-am
pump by connecting to it with a small
connecting adapter. This makes it possible
to measure carcinogenic and toxic substances in the ppb range possible even in
inaccessible locations such as canals, ducts
or tank facilities up to a distance of 147 ft.
Since the X-am pump also has explosion
protection certification for zone 0, it is ideally suited for these applications.
The X-act 7000 is manufactured by
Dräger Safety AG & Co. KGaA.

Process visualization
and reporting platform
AIS Software's Version 8.2 release of
the Universal Tag Locator (UTL) is an
enterprise-level process visualization and
reporting platform that aggregates realtime alarm, instrument, target, lab and
exceedance information across a facility's
stand-alone data silos into site-specific
shift reports, operator dashboards and
worker communications. Positive client
experience has proven the value of leveraging one central communication tool
for displaying operational data, reducing
critical alarm floods, targeting key process
values and removing the subtle barriers to
process optimization.
Version 8.2 enhancement highlights
include:
* Image manager
° Insert user-captured images
directly into shift reports, logs and
operator instructions
° Share images with other users
° Link images to specific units,
areas, systems or groups
* Alarm module improvements
° Export alarm metrics data into
new formats
° Create custom line, bar and
pie charts of tabular alarm data
° Option to bulk enter external
alarms
* Schedule target changes and
IOW/DOW off-limit overrides
° Schedule future target changes
and overrides
* Register module expansion
° Create blank paper forms that
can be completed in Class I
Div I environments
° Improve register searches
to capture more results over
longer time intervals
° Delete and archive registers
in bulk.
More than 150 enhancements have
been incorporated into the UTL platform. These include improvements to
register field logging and column formatting, expanding status change email notifications, better support for setting targets
based on PI tags, and custom handovers
embedded in shift reports.
