In alle industriële takken bestaat een trend naar miniaturisering. De noodzaak om producten kleiner te maken vormt echter een grote uitdaging voor de automatiseringstechnologie, bijvoorbeeld wanneer het gaat om het nauwkeurig aanbrengen van de juiste hoeveelheid soldeerpasta, lijm, smeermiddel, ingietmateriaal of afdichtingsmiddel. In de praktijk is dosering op grond van volume de eenvoudigste en flexibelste methode gebleken, want de aan te brengen substantie hoeft “alleen” maar naar het doseerpunt te worden geduwd door pompen die steeds dezelfde hoeveelheden afgeven.

Stelt u zich eens een balk voor die van Zürich tot Tokio reikt, zo'n 10.000 kilometer. Dan schuift iemand in Tokio er een vel papier onder. De seismometer die op het uiteinde in Zürich staat, slaat daarop uit en geeft de minimale wijziging in de hellingshoek exact aan. Zo ongel - oofl ijk precies zijn de instrumenten van de Zwitserse onderneming Streckeisen. In vakkringen is hun naam dan ook synoniem voor absolute topseismometers. Vier motoren van FAULHABER helpen de uiterst gevoelige sensoren betrouwbaar hun werk te doen

From consumer electronics to systems control, automotive technology to aviation and aerospace – today, electronics are absolutely essential in many sectors. They increasingly replace mechanical components, eliminating wear and tear and thereby extending the service life. What is easily forgotten in this regard is that electronics are also subject to the laws of mechanics.

High electric voltages are required for many applications. However, they always involve a potential danger. Static discharges and high field strengths, for instance, can easily destroy electronic components. If a discharge is accompanied by a spark, flammable vapors may even explode. In view of these hazards, shielding and grounding are mandatory in many areas. On the other hand, the advantages of electrostatic charging are frequently exploited by state-of-the-art technology, e.g. laser copiers, electrostatic application of coatings, or flue gas scrubbing.

Cables are a vital part of modern technology. They are an essential component when it comes to transferring electrical energy in a wide range of applications. A plastic insulating sleeve protects the conductive copper heart and prevents short-circuiting on external contact. The designs of the insulating sleeves are as varied as the cables themselves.

Material hardness is an important product attribute when parts are manufactured from flexible polymers. One measuring method in this area is Shore A hardness measuring. In this process, a test piece is pressed onto the material. The smaller the test needle used, the better tiny and ultra-miniature items can be measured. The most important factors here are an exact positioning and an exactly reproducible test sequence.

Particularly in the case of small and micro components with sensitive bearings, absolute concentricity over the lifecycle of the device is one factor that cannot be underestimated. After all, the ­higher the speed and non-symmetrical weight, the greater the forces involved. Alongside vibrations, this leads to increased strain on the bearings and thus to premature wear and tear.

Small is "in". As a consequence, the spread of miniaturization in automation is leading to ever increasing demands for optimum dosage of the tiniest quantities. Whether in electronics or micromechanical engineering: solder pastes, adhesives, lubricants, potting and sealing compounds have to be applied precisely where they are needed, in exactly the right dosage, with no spillage or dripping. Precision volume dosage units are the method of choice when high flexibility allied to exact application is essential. In line with their usage, units of this type also have to be extremely compact.

With all of the advances in electronics, mechanical measuring devices are indispensable, especially in superior mechanical and plant engineering. In order to always guarantee exact measurements, devices must be tested in certain time intervals, and must possibly be re-calibrated. However, this testing is time consuming, and therefore expensive.

Bulk materials are, more or less, finely powdered solids with a certain ability to flow. They are stored and handled in many fields of technology. However, their tendency to form inclined surfaces or solidify over time – even at rest – can lead to the formation of bridges or shafts which can hamper (homogenous) discharge from the silo. What is more, collapsing bridges in the silo can even lead to the destruction of the container. To design the silo or pipelines appropriately, the designer has to depend on well-grounded data regarding the flowability of the respective material.

There can be no doubt that the success­ful advance of digital photography ­will continue well into the future. But cameras with films are still required for special fields of ­application in photography, for example making aerial photographs for surveying purposes. These special-purpose devices, frequently weighing two hundred pounds, are far too valuable to be replaced by digital technology. Today the films are digitized with the help of high-quality scanners. Such applications call for accuracy and resolution levels in the range of micrometers.
