Fan blades inspired
from nature
Taking inspiration from
humpback whales, the company,
Ziehl-Abegg is developing its
new radial fan, that allows for
energy savings of up to 10 %. To
improve further, it was essential
to optimize the angle of
incidence between the air flow
and fan blade, which in turn
depends on the flow volume. The
movement of the whale fins
causes the angle to constantly
change. If its pectoral fins were at
an angle too steep to the flow this
would produce a lot of turbulence
as the water passes over
them. Changes in the fan blade
design, create an optimum angle
of flow over the entire span,
hence keeping the turbulence in
control and minimising the
losses. The bionic design of the
blade surfaces reduces the noise
level and its corrugated shape
gives additional strength and
optimises the weight.
Unique technology for stroke measurement in hydraulic
cylinders
Measuring the stroke of a hydraulic cylinders used in mobile machines
is an important task, as this enables the monitoring of the motions
further to be carried out. The company, Siko has developed a unique
system SGH10, for direct stroke measurement in hydraulic cylinders.
Other systems in the market are based on magneto-restrictive, inductive,
or hall based technology. In contrast to these systems, a wire-actuated
mechanism installed directly in the piston head is used to measure
the stroke. This means the entire system is built into the cylinder and cannot be influenced by the
environment. Another advantage is the reduction in costs as this does not need the sensor rods to be
integrated into the piston over the entire measuring path. In the SGH10, just one small thread is
needed in the piston to mount the cable. This allows the system to offer major potential cost savings
for hydraulic cylinders. Another highlight is that, this can even be used in telescopic ylinders.

Saving time during
assembly
Layher AG is expanding its
product line with the addition
of pressure switches with
integrated plugs. With types 471
and 472, Layher AG adds to the
previous models with integrated
plug, now with two and
three-pin Deutsch plug. This
eliminates the need for
connecting the cable. The
electrical contact is made
reliably and without complications,
simply by bringing
together the mating connectors.
Plug variants such as
M12x1, bayonet plug DIN72585
and Deutsch plugs 2P and 3P
are now available. Depending
on the plug variant, protection
classes up to IP67 or IP6K9K
can be achieved. The pressure
switches are available as
normally open, normally closed
or changeover contacts. They
are also available as a membrane
or piston switch in the
range from 0.5 bar to 350 bar.
