Wind power Solar energy

Balluff – at home in the world of energyGenerating and distributing energy is one of the most central tasks for coming generations.

Climate change, demographic trends and the limited availability of fossil fuels demand new, innovative solutions from the energy industry. Whether offshore wind farms or solar energy plants in the desert, the distribution of power generation to a large number of individual systems and the immediate influence of extreme environ-mental factors place stringent requirements on the quality of the components used. Balluff provides an important contribution for all areas of energy:

■■ With products for extracting coal, oil and gas, for conventional power generation and renewable energy from the wind, sun and water

■■ With components that feature outstanding safety, durability and reliability

■■ With a worldwide network made up of technical consulting, sales, after-sales service and spare parts supply

■■ With industry management specialized in the energy field■■ With close cooperation with plant engineers, suppliers of subsystems and renowned research and development institutions

Wind power generation is booming. Based on a worldwide installed capacity of 300 gigawatts in 2012/2013, an annual growth of up to 15 percent is forecast for the years to follow. In particular, offshore wind farms perform outstandingly well due to the high availability of wind resources and greater societal acceptance. Particularly there, however, the technical requirements for the installed components are especially high due to strong winds and the rough sea.

Every year more and more efficient solar thermal power plants are going into operation. In order to generate power of up to 100 megawatt and more, several 100,000 mirrors are aligned precisely and track the sun permanently. As these power plants are primarily installed in desert re-gions, the sensors used must not only have accurate control, but also withstand harsh environmental conditions.

Hydroelectric Power plant technology Oil/gas extraction

Hydroelectric power plants are the giants among the electric power plants. In addi-tion to their primary function as an energy supplier, they are gaining in importance as energy accumulators to compensate for fluctuating electricity production from wind and solar power plants. Mastering the immense forces of the water requires highly reliable closed-loop systems that work with the utmost precision.

Despite the fast pace of developments in expanding systems for using regenera-tive energy sources, oil, gas and coal will continue to play an important role. In some regions, forecasts even predict growth in the use of fossil fuels to generate electricity. Stringent requirements for safety standards and cost-effectiveness make the use of specifically designed components abso-lutely necessary.

Extracting oil and gas as a preliminary stage for using the fossil fuels for transportation, electricity production and in the chemical industry is becoming increasingly difficult in the face of vanishing resources. Whether using new methods or advancing into in-creasingly inhospitable regions: the climatic and mechanical loads are high, permitting no compromises in quality or reliability.

Micropulse transducer BTL

Balluff position measuring systems BTL were developed specifically for use in the hydraulic cylinders of wind power plants. Using the systems' pitch adjustment, the rotor blade angles can be adapted accu-rately to the wind speed to maximize power generation and ensure plant reliability.

■■ Contactless = low-maintenance■■ Pressure rated to 600 bar■■ Vibration and shock-resistant for use in adverse conditions without any problems

Greater performance

Inductive distance sensors BAW

Imbalances and wind loads shorten the ser-vice life of the bearings and the drive train. Inductive sensors BAW monitor compliance with tolerances at the critical locations (air gap). Thus they help to reduce loads and thus maximize the service life.

■■ Non-contacting, wear-free■■ Compact design■■ Simple installation, large distances

Longer service life

Wind energy – with the wind at its backWind power plants are high-tech power plants with high efficiency. And the demand is growing dramatically.

State-of-the-art plants for using wind energy feature an exception-ally high degree of efficiency. For example, the plants commonly in use today produce approximately 20 times more electricity than plants 20 years ago. They do so with a simultaneous reduction of costs of 30 percent. Still, wind farms are a large investment that require an availability of over 99 percent. This can be attained only if all components are extremely reliable and feature fail-safe performance. For this purpose, Balluff has long worked closely with leading manufacturers, offering industry-specific expertise and ensuring the highest quality. Tailored to the specific requirements of wind energy.

Disk brakes are used at various locations in wind power plants. With their durability and precise measurement, inductive sensors BAW monitor these brake disks continuous-ly and provide a timely warning if the brake pads need to be changed.

■■ Wide measuring range■■ Continuous detection■■ Compact design

Better maintenance

Inclination sensors BSI

Particularly during strong gusts of wind, storms or a wind energy plant's start-up phase, a strong tilt of the tower can shorten the overall plant lifetime. Inclination sensors BSI from Balluff measure the absolute incli-nation angle reliably, preventing limit values from being exceeded and reducing the load on the plant.

■■ Easy installation■■ Temperature range –40 to +85°C■■ Rugged metal housing

Decreased load

Capacitive sensors BCS

Capacitive sensors BCS detect maximum and minimum levels, both in the expansion tanks of the cooling system and of the gear-box and hydraulic system. Without direct contact, through the container wall or using adapters. They are installed in the oil pan as a leak sensor and report oil loss reliably.

■■ HALT tested capacitive sensors ■■ measure through plastic walls■■ detect oil and water

Favorable inland locations for wind power plants are becoming scarce. Moreover, the installation of additional plants in densely populated areas meets with increasing resistance. Therefore, large offshore wind farms are coming increasingly into the spotlight. One reason is that the ocean offers plenty of space for even very large plants; another is that the energy yield is up to 40 percent higher than on land. However, the advantages are offset by even higher requirements for the durability and quality of the wind power plants. Higher wind loads, permanent moisture and the salty air demand the uncompromising use of failsafe components.

Offshore wind power – fighting the wind and wavesWith abundant available space, high acceptance and a large energy yield, offshore wind farms are up and coming.

Inductive sensors BES

Inductive sensors BES from Balluff detect the rotor speed in wind power plants. Extremely reliable, even at temperatures up to –40 °C. Two inductive sensors aimed at the locking plate are sufficient for detect-ing the speed and direction of rotation and protecting the plant from overspeed.

■■ High switching distance■■ Extended temperature range■■ Contactless detection■■ Insensitive to contamination

High reliability

Magnetically coded position and angle measurement system BML

Magnetic tape measuring systems BML are attached to the main shaft and are extremely accurate, even at very slow speeds. In addition, it is not only possible to detect the direction of rotation, but also to detect the correct rotor position for the rotor lock using reference points. All of this is non-con-tact and thus wear-free.

■■ Extremely accurate, even at very low speeds

■■ Non-contact = wear-free■■ Approach of positions possible

Extreme accuracy

The generator speed is an important param-eter for controlling the plant. Balluff sensors read the poles on the magnet ring without contact and can be used flexibly due to the variety of ring diameters or as band solutions, even on large-diameter shafts. Maximum durability and precision are the outstanding features of the measuring systems BML with magnet ring, which stand for optimal control quality for the feed-in.

■■ Simple, space-saving installation■■ Non-contact = maximum service life■■ High precision thanks to high resolution

Optimal control quality

High-pressure resistant inductive sensors BHS

The wind energy plant must be at a stand-still for maintenance. For this purpose, the rotor blades are moved out of the wind. The inductive sensors BHS help to determine the piston position of the locking cylinder and the end position of the cylinder for hydraulic pitch systems reliably.

■■ Pressure rated to 500 bar, can be installed directly

■■ Stainless steel housing■■ Also available in analog version for soft stop

Reliable position determination


The inductive sensors BES measure the position directly at the gear ring of the azi-muth adjustment and are used (as in speed measurement) for the yaw system. The cost-effective BES sensors are particularly well suited as a redundant addition to the standard rotary encoder solution.

■■ Rugged, non-contact■■ Suitable for wide temperature and humidity fluctuations

■■ Stainless steel housing■■ Shock and vibration proof

Solar power plants – really heating things upThe sun provides many times more energy than the world needs. No other source of energy has as much potential.

Direct measurementLow wear

When talking about the sun as an energy source, we usually think mostly in terms of photovoltaics. However, directly converting sunlight into electric current via photovoltaic modules is only one way to make use of the sun's nearly inexhaustible potential. Solar thermal power plants, on the other hand, concentrate the sunlight and heat up a heat transfer medium. In concentrated solar power plants, this can be up to 1000 °C. For this purpose, mirrors have to be aligned accurately and adjusted constantly to track the sun. Balluff has developed measuring systems to measure these movements reliably and increase the efficiency of the plants.


With the parabolic trough power plant, parabolic trough collectors concentrate solar energy onto a receiver tube positioned in the focal line and heat up the synthetic oil flowing in it. For high efficiency, all troughs have to be continuously adjusted to follow the sun's path and be focused exactly on the receiver tubes.

■■ Direct measurement■■ Precise position detection■■ Determining reference points


With concentrated solar power plants, heliostats focus the sunlight onto the central receiver in the top of the tower. The positioning accuracy of the heliostats contributes substantially to the efficiency of the system. Usage in desert areas places high demands on the quality of the sensors. To prevent downtime, sensors that are as maintenance-free as possible are required.

■■ Non-contact, low-wear and low-maintenance

■■ Cost-effective installation■■ High accuracy

Cost-effective solutionHigh accuracy Easy installation


For position detection in linear drives, the inductive sensor BES does not return an abso-lute position, but only detects the change of position by counting pulses. Inductive sen-sors are the most cost-effective solution for many position detection applications.

■■ Large switching distance■■ Extended temperature range


The required high temperatures can be achieved only by optimum alignment of the parabolic troughs to the position of the sun. Absolute inclination sensors BSI ensure precise positioning and thus increase the efficiency of the solar energy system.

■■ Installation made easy by compact, robust metal housing

■■ Continuous position detection, even after a power failure

■■ High accuracy over a full 360 degrees■■ No reference run required


With Fresnel mirror collectors, the flat mirror strips arranged in parallel reflect the sunlight onto a fixed absorber tube and heat up the water flowing through it. For high efficiency, the inclination sensors BSI enable exact alignment of each individual mirror strip onto the common focal point.

■■ No reference run required■■ High accuracy■■ Compact dimensions■■ Easy installation

Despite a wide variety of installed hydroelectric power plants and sophisticated systems for generating electric energy, the potential of hydroelectric power is still far from being exhausted. Advanced turbine and control concepts adjust the stator and impeller or nozzle and stream deflector exactly, depending on the power re-quirement and water level. Transducers from Balluff reliably support these concepts and contribute to the optimization of processes.

Hydroelectric power – in the flowFor millennia now, humans have used the power of water. Today, water power is an indispensable component of today's energy mix.


Turbines need to run smoothly and evenly. To accomplish this in Kaplan turbines, the position of the guide vanes can be adjusted as needed. Use profile micropulse transducers BTL from Balluff to control your turbines reliably and safely.

■■ Extremely reliable■■ No reference run required after voltage interruption

■■ Rugged, non-contacting

Reliable control


In addition to adjusting the guide vanes, the turbine efficiency of Kaplan turbines is also adapted to the water volume by adjusting the runner blades. The transducer BTL, which is integrated into the shaft, provides for optimum adjustment of the impeller and efficient control of the output.

■■ High protection class■■ Pressure-rated for installation inside hydraulic cylinders

Efficient power adaptation


In Pelton turbines, the speed of the impel-ler, and thereby the output produced, is controlled via nozzles in the water jet. A high pressure of up to 200 bar exists at several inlet nozzles and has to be adjusted quickly and reliably.

■■ Reliable and rugged■■ Compact design

Hydroelectric power – in the flowFor millennia now, humans have used the power of water. Today, water power is an indispensable component of today's energy mix.

High pressure rating Compact design


Floating debris at the inlet of hydroelectric power plants causes efficiency losses and thus impairs the cost-effectiveness. In the worst-case scenario, stopping the system can result in high costs. With the high-pres-sure resistant inductive sensors BHS, the end positions on the rake can be easily and reliably detected.

■■ High pressure rating■■ Easy installation


Today's requirements on a weir far exceed the mere opening or closing of a gate. In addition to preparing paths directed upstream for fish, fully automatic control of the water level has now become standard. For this purpose, the inclination sensors BSI reliably enable the precise detection of intermediate positions.

■■ Large temperature range■■ Analog output 4 to 20 mA

The technologies for using marine energy to generate power are still relatively young. Balluff not only provides sensors for marine power plants, but is also in close contact with research projects and provides innova-tive solutions for new developments and prototypes.

More efficient and environmentally friendly combustion processes in conventional power plants require turbines and generators that can be controlled with high accuracy. Besides this continu-ous increase in efficiency of energy generation from fossil fuels, the topic of reliability is of high importance. With its specially devel-oped sensors, Balluff meets the high demands on accuracy and reliability associated with this topic.

Conventional power plants – the reliable basisOil, coal and gas are still indispensable sources of energy. And they will continue to be so for the foreseeable future.

Fast and easy startup is enabled by start points and endpoints that can be set with a computer as well as by the easy application of parameter sets.

■■ 2 or 3 completely separate systems in one housing for maximum safety

■■ With a measuring range of up to 7620 mm, it is also suitable for large valves

■■ Compact, space-saving housing■■ Fast startup■■ Non-contact and wear-free■■ Monitoring of all channels via LEDs


Quick-action shutoff control valves have the highest reliability requirements, which can be met only by a redundant system. In the redundant micropulse transducer BTL 7, up to three independent measure-ment sections and three independent elec-tronics systems are compactly integrated in a rod. The robust, non-contact and absolute position measuring system is freely configurable. Thanks to its compact dimen-sions, it can easily replace already installed, non-redundant position measuring systems.

Oil and gas extraction – race against timeEver-dwindling resources require ever better technology for extracting fossil fuels.

Oil and gas still make a critical contribution to generation of en-ergy. But the growing scarcity of resources demands ever greater effort for extracting fossil fuels and the employment of new, more efficient methods. Harsh ambient conditions and high mechanical loads also represent a tough endurance test for people and materials. Balluff makes an important contribution here with robust,

precise and low-maintenance sensors. Explosion protection with numerous international certifications is a matter of course for Balluff.


Control and shutoff valves are used in many areas of oil and gas extraction, in refiner-ies as well as in petrochemical plants. In addition to high reliability even in very harsh environments, explosion protection in par-ticular has the utmost priority in an environ-ment with corresponding hazards. Certified transducers BTL from Balluff guarantee reliable and safe usage.

■■ High reliability■■ With IECEx, ATEX, FM, and many other international approvals

Explosion protection


After tapping an oil field, crude oil pumps do their work entirely autonomously for the most part. Pump parameters are continu-ously monitored via sensors and, usually, via automated remote systems. Balluff Micropulse profiles prove themselves in the difficult application directly on the pump and guarantee reliable monitoring of position and path.

■■ Robust design■■ Exact measurement of path and position

Highly accurate position measurement


To minimize load and wear, crude oil pumps have to be aligned exactly over the borehole. Balluff inclination sensors BSI are ideal for use in harsh outdoor environ-ments. Thanks to their analog angle values, the pumps can be positioned with extreme precision.

■■ High protection class IP 67 – suitable for use in rough conditions

■■ Precise, absolute angle measurement■■ Compact housing

Hydraulics – under high pressureRegardless of how energy is generated: Hydraulic systems always play an important role.

In power plants, hydraulic systems are used for regulating and con-trolling numerous processes. The powerful heart of these systems is the hydraulic power unit, which generates the required pressure. Of a corresponding magnitude are the demands on pressure sen-sors with respect to accuracy, integration capability, and reliability.

Pressure sensors from Balluff meet all of these demands and feature an excellent price/performance ratio.

Pressure sensors BSP

With their large display and a simple operat-ing concept in accordance with VDMA, Balluff pressure sensors BSP are straight-forward and quick to configure. Since the display and electrical output can be turned into a position independent of the flange, Balluff pressure sensors can be installed flexibly and in a space-saving manner.

■■ Compact housing design■■ Local pressure display■■ Binary switching outputs■■ Analog output signals■■ Optionally up to –40 °C

Fast configuration of parameters

Capacitive sensors BCS

A sufficient hydraulic fluid level is prerequi-site for interference-free operation of a hydraulic system. Therefore continuous level monitoring plays an important role. The capacitive sensors BCS from Balluff reliably detect the maximum filling level in hydrau-lic tanks. They reliably report leaks when installed in the oil pan as a leak sensor.

■■ BCS reliably detects minimum and maximum levels

■■ Usage in a broad temperature range

Regulating and controlling – everything under controlA system is only as good as the technology controlling it. The significance of individual components is often underestimated here.

When we talk about the reliability of plant and control engineer-ing, we often think first of the quality of the large components. Frequently, however, it is the less-noticed components in the background that are responsible for interruptions or even failures. Primarily the power supply, with implications for all system compo-

nents. Yet cables and electrical connections also play an important role. After all, they transmit the sensor signals and report position and pressure as well as other parameters to the controller.

Power supply units BAE

A reliable power supply is prerequisite for particularly efficient operation of systems and machines. Intelligent power supply units BAE from Balluff guarantee a high degree of reliability. Load and stress levels can be seen immediately with the LEDs, which in turn enables the operator to make optimum use of the output and assess the remaining service life.

■■ Continuous monitoring of machines and systems

■■ Easy monitoring via LEDs■■ Reliable power supply units guarantee efficient operation

■■ Optimized use of devices and a longer service life

■■ Maintenance planning

Intelligent network monitoring

Connectors BCC

Each system is only as good as its weakest component. This also applies to electrical systems. And here it is often the connec-tions whose significance for signal quality and reliability is underestimated. Here as well, Balluff makes no compromises, but instead pursues the same quality demands for plug connectors and cables as for its sensors and components.

Many years of experience, comprehensive design engineering expertise and high production standards are the prerequisites for first-class products. However, only the use of intensive test methods even during design engineering, as well as during and after production, guarantees compliance with the promised product characteristics. Therefore, Balluff has an in-house testing laboratory that is approved by German accreditation body DAkkS for testing electromagnetic compatibility. Furthermore, shock, sinewave and noise testing can be

carried out, as well as product-specific testing including x-ray analysis and HALT testing.

During the HALT (High Accelerated Lifetime) test, modules are subjected to an acceler-ated aging process. This allows weak points in the product design and manufacturing process to be discovered quickly, with just a few prototypes. In a special chamber, the test objects are subjected to alternating increments of very low and very high tem-peratures as well as an extreme tempera-ture change. This makes it possible to attain a temperature range of –100 °C to +200 °C with a temperature gradient of up to 70 K/min. This is followed by vibration tests with maximum loads of 50 G until the unit finally reaches its limit and is destroyed. The toughest test procedure is the combination of the temperature and vibration test.

In-house testing laboratoryCertifications HALT test

Testing and certification – inspected qualitySafe, low-maintenance, robust – components for power plants have to meet stringent requirements.

At Balluff, high product reliability, low maintenance effort and a long service life are not empty promises, but the result of many years of experience and systematic quality control. As early as the develop-ment phase, the sensors are subjected to an accelerated aging process in our in-house testing facility to identify weak points at an

early stage. In this HALT (High Accelerated Lifetime) test, a gradual temperature increase, fast temperature changes and vibration tests simulate the loads to which a sensor is exposed over its entire product life. Numerous certifications such as CE, CCC, UL, cULus and GOST are proof of the high quality standards at Balluff.
