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

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