Precision Monitoring & Measuring

Accuracy and resolution in the micrometer range as well as exactly reproducible test procedures are required in modern measurement and testing technology. Here, FAULHABER drive systems provide precise control dynamics and a high power density in a minimum amount of space.

Application Highlights

Dosing pump

The miniaturization trend extends across all industries; however, the ever-decreasing product sizes are a challenge to the automation technology, e.g. when it comes to accurately applying the correct amount of soldering paste, adhesive, lubricant, potting material or sealant. Dosing according to volume has been proven to be the simplest and most flexible method in practice, since the substance that needs to be delivered “only” needs to be moved back to the dosing tip by pumps delivering uniform quantities.

Test systems for car doors

Product life cycles are becoming shorter in all areas of industry. New products appear on the market faster and faster. This trend is particularly evident in the automotive sector. While not so long ago it still took seven to eight years before a vehicle was ready for production, today it is just two-and-a-half to three years. This places high demands on the development team. Vehicle functions, such as the frequent opening and closing of the door, must be tested quickly and precisely so that any necessary optimisations can be performed on short order.

Broadband seismometers

Imagine a bar that extends from Zurich to Tokyo, more than 10,000 kilometres. Now someone in Tokyo slides a piece of paper beneath it. The seismometer at the Zurich end then reacts and precisely indicates the minimal change to the inclination angle. This unbelievable precision is achieved by devices from Swiss company Streckeisen, whose name is synonymous with high-performance seismometers within expert groups. Four FAULHABER motors contribute to making the highly sensitive sensors carry out their work reliably.

Condor Sigma test device

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.

Electric field meters

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.

Stripping machines

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.

Nanomeasurement

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.

Horizontal Balancing Machines

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.

Precision dispenser

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.

Dial Gauge Testing

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.

Ring shear tester

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.

Geo-Scanner

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.
