Wind turbines play an important role in the energy transition as they have an energy payback time of only a few months. Pepperl+Fuchs offers the right automation technology for both new construction and retrofitting of existing plants. Signal conditioners ensure interference-free signal transmission, while surge protectors safeguard wind turbines from overvoltage, for example caused by lightning. In this way, the Pepperl+Fuchs products guarantee safe and reliable processes in wind energy.
Frequency converters from Pepperl+Fuchs, in combination with inductive sensors, enable reliable detection of the rotational speed. This ensures that the speed of the generator does not exceed certain limits.
Pepperl+Fuchs signal converters transmit analog signals to the controller via galvanic isolation. In wind turbines, for example, temperature converters record the values from temperature sensors and transmit them safely. This makes it possible to monitor that oils or oil films on the drive shaft of the generator do not become too hot.
Transmitter power supplies from Pepperl+Fuchs are used in wind turbines for pressure measurement. They transmit signals from pressure transducers to monitor the oil pressure of the generator shaft.
Wind turbines are up to 200 meters high and therefore very susceptible to lightning. Pepperl+Fuchs offers a complete product portfolio designed for surge protection: The modules reliably discharge surges via grounding, therefore protecting people and equipment. Suitable devices are available for signal and supply lines as well as for fieldbus infrastructure.
The new LB/FB PROFINET gateways from Pepperl+Fuchs open the door for IIoT 4.0 applications in process industries.
