Scaling enables fiber-optic measurement in every rotor blade
Munich, May 2, 2018 – fos4X introduces the new generation of measuring devices – the Blackbird OECD – into the fos4Blade sensor platform. Thus, a significant increase in the number of units is achieved while increasing the range of functions and even more attractive prices.
Advantages of Blackbird OECD
The Blackbird OECD (opto electronic converter device) is a fiber-optic measuring device, which was developed especially for use in the hub of wind turbines and therefore forms the heart of the fos4Blade sensor platform.
The advantages of the new generation are:
- cost-effective – cheaper than conventional electrical sensors
- optimally adapted to the requirements of wind power
- the same form factor for up to 5 measuring channels per rotor blade
- Integrated signal preprocessing including sensor data fusion
- Open interfaces (fieldbuses and OPC-UA)
“The Blackbird simplifies the necessary scaling of our production. We are now able to produce very large quantities and be even more cost competitive. This brings us a big step closer to our goal of integrating fiber-optic sensors into every new rotor blade.”
says Dr. Lars Hoffmann, CEO of fos4X.
fos4Blade sensor platform
The fos4Blade sensor platform is designed to be the new standard for rotor blade sensing. It consists of several fiber optic strain sensors and fiber optic vibration sensors per rotor blade, as well as the fiber optic measuring device Blackbird OECD.
The sensors are monitored by the measurement device. The fiber-optic measured variables are finally translated by the Blade Physics Library into easy-to-use parameters of the rotor and are provided by Fieldbus or IIoT interfaces.
Future higher functionality
Due to the higher computing power of the measuring device, important calculations for the optimization of wind turbines or wind farms can be calculated directly in the measuring device in the future.
The Blackbird OECD replaces the previous measuring device fos4Test as a new measuring device generation in the field of series products. Since also the fos4Test (of Test & Measurement) always had the internal working name “Redhawk”, also the new measuring device of this tradition should remain faithful to the use of bird names. The choice finally fell on Blackbird.
“With the Blackbird, we want to advance the scalability of our measuring system and come closer to our goal of integrating sensor technology into every new rotor blade. The small, agile and widespread blackbird is a perfectly adapted to their environment bird species and therefore a very appropriate eponym.”
says Markus Schmid, CTO of fos4X.
