Wind power HIGH-TECH POWER PLANTS WITH HIGH EFFICIENCY Modern wind power systems deliver extremely high efficiency. For example, today's plants produce approximately 20 times more electricity than plants 20 years ago – and at lower cost. Still, wind farms are a large investment that requires high availability of the parts. This can be achieved only if all components are extremely reliable and feature fail-safe performance. To this end, Balluff has long been working closely together with leading manufacturers. We offer you industry-specific know-how and ensure the highest level of quality – for...

ROTOR BLADE PITCH CONTROL With BTL magnetostrictive linear position sensors HOLD TOLERANCES With BAW inductive distance sensors MONITOR BRAKES With BAW inductive distance sensors MEASURE TOWER FLEX With BSI inclination sensors MONITOR LEVELS With BCS capacitive sensors Our magnetostrictive linear position sensors have been especially developed for use in the hydraulic cylinders of wind turbines. Using the systems' pitch adjustment, the rotor blade angles can be adjusted precisely to the wind speed to maximize power generation and ensure system reliability. Imbalances and wind loads shorten the...

DETECT ROTOR SPEED With BES inductive sensors MONITOR LOW SPEEDS With BML magnetic encoders ENSURE OPTIMAL CONTROL QUALITY With BML magnetic encoders DETERMINE POSITION With BHS pressure-rated inductive sensors DETECT AZIMUTH ADJUSTMENT With BES inductive sensors Inductive sensors from Balluff detect the rotor speed in your turbine with extreme reliability even at temperatures –40 °C. Two inductive sensors aimed at the rotor lock are all you need for detecting the speed and direction of rotation and protecting the plant from overspeed. Our magnetic encoders are also extremely precise at very...

Solar power plants THE SUN CAN PROVIDE MORE ENERGY THAN THE WORLD NEEDS Solar-thermal power plants can today deliver power outputs of 100 megawatts or more. To generate this energy, many thousands of mirrors need to be aligned precisely and continuously with the sun. This requires exceptionally precise sensors which can also withstand the extreme environmental conditions found, for example, in desert regions. We have developed measurement systems that allow you to reliably detect these movements and realize efficient plants.

POSITION HELIOSTATS With BML magnetic encoders POSITION PARABOLIC TROUGHS With BML magnetic encoders TRACK PARABOLIC TROUGHS With BSI inclination sensors ADJUST FRESNEL MIRRORS With BSI inclination sensors DETECT POSITIONS IN LINEAR DRIVES With BES inductive sensors Ensure the efficiency of the solar power plant by precisely positioning the heliostats. Here the sensors need to meet particularly strict requirements. With our highly precise magnetic encoder system you are ideally positioned even under the harsh conditions of desert regions. It operates contactlessly and is therefore very low-maintenance,...

INDISPENSABLE IN THE MIX OF RENEWABLE ENERGY SOURCES Hydroelectric power is indispensable among renewable energies these days and still harbors plenty of untapped potential. To reliably operate the enormous hydroelectric plants you need dependable, extremely precise working control and regulating systems. Balluff helps you with high-precision solutions using sensors and linear measurement systems.

CONTROL KAPLAN TURBINES With BTL magnetostrictive linear position sensors TRACK PRESSURE With BTL magnetostrictive linear position sensors MONITOR SHAFT POSITION AND SPEED With BML magnetic encoders SHUT OFF FLOW With BHS pressure-rated inductive sensors DETECT RAKE POSITION With BHS pressure-rated inductive sensors DETECT INTERMEDIATE POSITIONS With BSI inclination sensors For Kaplan turbines to run evenly, the position of the runner and guide vanes is adjusted to respond to need changes. With our magnetostrictive linear position sensors, you control your turbines efficiently and optimize their...

Conventional power plants ENERGY PROVIDERS THAT ARE STILL IMPORTANT Efficient and environmentally friendly combustion processes in conventional power plants require turbines and generators that can be controlled with great accuracy, for example in peak power stations. At the same time, the efficiency needs to be continually increased while ensuring availability. Your demands on the technology are extremely high here, and with good reason. By using extremely precise solutions from Balluff which were developed just for such applications, you can easily meet these demands.

USE QUICK CLOSING CHECK VALVES With BTL magnetostrictive linear position sensors Quick acting control valves are subject to the highest requirements that often can only be met by a redundant system. Our BTL 7 magnetostrictive linear position sensor incorporates up to three independent measurement sections and three independent electronic systems in one rod. The robust, contact-free and absolute position measurement system is freely configurable. And: thanks to its compact dimensions, it can easily replace already installed, non-redundant position measuring systems. Startpoints and endpoints can...
