Renewable Energies The conversion of wind power into electrical energy is an immensely sensitive task - even for experts. In principle, a rotor (generally known as a “wind turbine”) is set in motion by an air flow and a connected generator, driven by the kinetic power, produces electric current. Since, however, wind speeds are never constant, a control system which works precisely must enable the system to be tuned for both high and low wind velocities. Modern plants use a ‘pitch system’ for this, which optimally adjusts the rotor blades to changes in the force acting on them - and (in...

Renewable Energies Application example: Hydraulic system Examples of where pressure measurement is needed are in the hydraulic systems and in the lubricant cycle. In addition, for example, brake control and transmission oil cooling must be reliably monitored. The measuring systems used must be particularly reliable and – when using electronic pressure measuring instruments - by high insulation strength, to ensure that the plant operates efficiently and safely.

Renewable Energies Hydropower is the most significant form of renewable energy in the world. Its use is based on its large availability and technology matured over the past 100 years. The plants in operation, such as running water, reservoir and pump-fed power stations, achieve high efficiencies: They can convert up to 90% of their energy source into electricity. In the search for alternatives, the focus has shifted to the seas. In an innovative project on the north coast of Portugal, ‘wave converters’ are anchored in the sea to generate power. It is made up of a 150 metre-long, flexible...

Renewable Energies Application example: Wave energy converter For the operating sequence of the wave energy converter, the monitoring and control of the hydraulic pressure is central. The major task here is the adjustment of the movement to the current wave strength and length, in order to obtain the optimum energy output and to minimize the mechanical load on the structure. In addition, the pressure generation, in terms of both speed and strength, is monitored and then evaluated by the intelligent control unit. The measurement technology used must be as reliable as it must be strong, due...

Renewable Energies On each square metre of the earth‘s surface, the sun’s radiation produces on average a thermal output which corresponds to one small heater, i.e. m nearly 1.4 kW. If one could use this energy at the same time everywhere, the global heat requirement would be covered at least 6,000 times over. There are various techniques to convert solar power into usable heat. In principle a solar collector absorbs the heating energy from the sun’s radiation and passes it on via a suitable medium, usually liquid antifreeze, to a heat exchanger. There the household mains water is warmed up...
