Automation of wind turbines.
To survive on the energy market, wind turbines need to be powerful
and efficient. Besides high uptime, suitability for all climatic zones is
absolutely necessary. Plant operators have special demands on the
components installed to ensure that they stand up to different environ-
mental conditions. Besides high temperature fluctuations they include
shock and vibration stress. The sensors and systems from ifm electronic
are optimised for these different demands on performance – at an
excellent price / performance ratio. Diverse approvals certify their
reliable operation. Test us!

Automation of solar tracking systems.
The solar panels of a photovoltaic system or the parabolic reflectors of
a solar thermal system are adjusted for maximum energy yield. UV rays,
sand, temperature fluctuations and humidity affect the sensors of the
tracking systems. ifm electronic is known for robust sensors for out-
door applications. Among them are various sensors for position detec-
tion. Once adjusted, they are maintenance and wear free. The sensors
from ifm stand out with their reliability, long life and quality.
