Innovations
Next-generation machine
visualization solution
differentiates OEM
systems, improves
user operations
Machine builders in any industrial
application can now use Emerson's PACSystems™
RXi HMI (FIG. 2), a next-generation
machine visualization solution
designed to help set its systems apart
for customers. The new system easily
helps users overcome the limitations of
lower budgets, fewer people and higher
productivity demands. This highly intuitive
human-machine interface (HMI)
addresses the needs of today's industrial
workforce with easy-to-use, smartphonelike
graphical displays without sacrificing
rugged, industrial performance.
Unlike traditional resistive displays,
PACSystems RXi HMI is designed with
projective capacitive touchscreen technology
that allows users to interact with
the visual display with 10-point multitouch
capabilities like swipe, pinch or
zoom to move to the next screen or expand
a chart, enabling easy operation by
a wide range of personnel with varying
levels of training and experience.
PACSystems RXi HMI comes preloaded
and pre-licensed with the advanced
Movicon™ WebHMI software,
so the device is conveniently ready to
operate out of the box, saving customers
time. PACSystems RXi HMI is HTML5ready,
which allows users to collaborate
from anywhere so operations, management
and maintenance teams can all
view the same screen at the same time,
no matter the distance. This immediate
sharing of information and access to expertise
reduces maintenance costs and
improves productivity.
In addition, customers will value the
faster access to data-based operational
insights to maximize overall equipment
effectiveness. The PACSystems RXi
HMI, with Movicon WebHMI at its core,
is IIoT-ready for data analysis, troubleshooting
and diagnostics, placing the operational
insights customers need at their
fingertips. A data trending tool provides a
clear snapshot of productivity and quality.
The SQLite database tool and PAC analyzer
help users troubleshoot problems
and minimize downtime. In addition,
it provides extensive protocol support
with OPC UA for better data contextualization
and MQTT for easy cloud connectivity-the
solution goes far beyond
visualization.
PACSystems RXi HMI protects
against both physical and digital risks. It
offers protection in wet applications with
certifications for both high-pressure water
jets and marine use with an IP66 water
resistance rating, and is approved for
use in a wide range of temperatures from
-20°C-65°C. In addition, the device is
resistant to chemicals, impact, scratches
and dust. It is also designed in accordance
with IEC 62443 Global Automation Cybersecurity
Standards to support end users'
overall digital security strategy.
General duty single
cartridge seal
Chesterton, a global leader in equipment
sealing and reliability, has released its
newest mechanical seal product: the 1510
general duty single cartridge seal (FIG. 3).
Accompanying the recently released
1810/2810 high-performance seals, this
seal represents another foundational
component for Chesterton's cartridge
seal portfolio and future mechanical seal
business. Designed with a compact cartridge
profile and utilizing the Chesterton
T.A.B.S. (Tapered Adjustable Bolting
System) field proven on the 155 and
442 split seals, the 1510 is designed to fit
and install easily on process equipment
throughout industry. The unique resettable
centering strap allows for impeller
adjustments even after the seal has been
fitted. Incorporating Chesterton's five
key features of good mechanical seal design,
the 1510 sets the new standard for
general duty cartridge seals.
Rupture disk improves
process performance
and efficiency
OsecoElfab has launched the technically
advanced LoKr reverse rupture disk
for chemical process and petrochemical
plants. The new disk design delivers a
best-in-class flow resistance factor, or KR,
to maximize pressure-relieving performance
while delivering superior reliability
and extraordinary service life.
The LoKr represents the next generation
of design and engineering in pressure
relief technology. The disk's architecture

has been refined and optimized to improve
performance in three key areas:
keeping pressure drops in relief lines to
an absolute minimum, providing maximum
reliability and accuracy, and being
suitable for the widest range of pressures,
temperatures and line sizes possible.
The reverse-buckling disk combines
a dimple on the disk with an innovative
knuckle on the holder to offer full-bore
opening with exceptionally accurate burst
ratings. This enables a higher flowrate on
burst than previously possible, demonstrated
by the disk's low KR value of 0.22.
This makes it easier to keep pressure drops
across the relief line below 3%, when the
LoKr is used in relief valve isolation. Process
plants can continue to use smaller
piping diameters with no loss of performance
or efficiency, even at low flowrates.
LoKr offers superior reliability, a wider
size range, a lower KR and improved safety
compared to other designs currently available,
according to the company. Designed
to ASME XIII standards and certified with
a UD stamp at a best-in-class KR value of
0.22, the LoKr is now available.
