sensor and the PP20H pressure sensor
(photo), work both in conventional
control topologies and digital IO-Link
control environments. In process automation,
an analog interface is helpful
for sensor integration into existing control
concepts. For sensor commissioning,
IO-Link provides advantages, such
as easy and fast parameterization or
access to secondary data. For process
control, a parallel readout of conductivity
or pressure is enabled via 4-20-mA
analog output. IO-Link provides access
to valuable secondary data, such as
process and sensor temperature. Such
information can detect, for instance,
unusual temperature rise in containers
or pipes for predictive maintenance
purposes. - Baumer MDS GmbH,

A new check valve with
redundant sealing
The new Model CV check valve
(photo) features a sealing system with
a self-centering piston, which reliably
prevents backflow of liquid and gaseous
media. The reliability of the new
instrumentation valve is mainly due to
its redundant sealing, consisting of an
O-ring and a metal cone. Its leak-tightness
has been tested in accordance
with BS6755/ISO 5208 leakage rate
A. The solid-machined, robust design
of the Model CV ensures high repeatability
and a long service life, even in
heavy-duty applications. An application-specific
assembly with a measuring
instrument is offered. Such an
instrument hook-up is delivered readyto-install
and leak tested. - WIKA

Transform buildings into
high-performing assets
The new generation of building automation
controllers, Desigo PXC4 and
PXC5 (photo), offers a wide range of
benefits for automating small- and
medium-sized buildings. Thanks to
the new, license-free Desigo Engineering
Framework, devices can now
be seamlessly integrated in the same
framework. Both controllers were designed
to expand and strengthen the
Desigo portfolio and focus on one
specific automation element - the
Desigo PXC4 for heating, ventilation,
air-conditioning (HVAC) plants; and
the Desigo PXC5 for system functions
and integration. The new controllers
were simultaneously released with
the Desigo Engineering Framework,
which consists of the HIT Portal, a
web-based planning and selection
tool; the engineering and commissioning
tool ABT Site for PC users; and the
commissioning tool ABT Go application
(app) for mobile use. - Siemens

New hollow-socket shaft design
for coupling-free installations
Couplings are a common failure point
within drive systems. Keeping shafts
aligned not only eliminates vibrations,
but also prevents additional load and
wear-and-tear on drive units. Unfortunately,
this presents several challenges,
and even the most seasoned
technicians are required to adjust and
shim, sometimes for hours, to get as
close to perfect alignment as possible,
knowing that even the slightest
misalignment will ultimately shorten
the lifecycle of the gear unit. The new
hollow-socket shaft design for Nordbloc.1
single-reduction gear units
(photo) features a shaft design that
mounts directly to a pump without
the need for couplings. This significantly
reduces installation time and
maintenance, greatly extends the
operating life of the unit, and drastically
reduces revenue loss as a result
of unexpected downtime, says the
manufacturer. - NORD Gear Corp.,

PLC with direct cloud connection
and multiprotocol ethernet
The TBEN-L programmable logic controller
(PLC; photo, p. 22) is said to
be the world's first IP67 controller for
industrial
applications. The TBEN-L
PLC not only offers an onboard Codesys
PLC, but also enables a cloud
connection and communication with
different Ethernet protocols at the
same time, thanks to its multiprotocol
technology. The new Dual MAC mode
enables the module to establish a connection
to the automation network via
