MaInno - New approaches in the production of measuring tapes

Measurement is an elementary part of any development. Whilst complex measurement methods are necessary in the case of very large or very small quantities, measuring tapes are generally used to measure quantities in the range that is detectable by the human eye....

POF-Control - Measurement, control, and switching

Since its foundation in 2001, the Polymer Optical Fiber Application Center (POF-AC) at the Ohm has pursued the objective of conducting applied research into polymer optical fibres (POF) in the fields of data transmission, sensor technology, and lighting technology....

POF-MEM - POF fouling sensor for membrane processes

Drinking water in Germany is largely derived from ground water. However, surface waters such as well water also contribute to the supply. Often this must be treated before it is drinkable or suitable for industrial production. For water softening and desalification, reverse osmosis (RO) is currently the most important process.... more about this project (project profile in German)

UFUS-POF - Colour-change sensors with polymer fibres

In recent years, the use of polymer optical fibres (POF) has been examined primarily for the purpose of short-distance data communications, however their use in the field of sensor technology is becoming an increasingly attractive proposition. In the “Universal Colour-Change Sensor with Polymer Fibres” project, (funded by the Staedtler Stiftung) at the Ohm’s POF-AC, research is now under way to determine how colour-change reactions can be used to detect a variety of substances with the help of POF-based sensors....

ST-POF - Switching using polymer optical fibres

As a result of the planned energy transition and the associated expansion in high-voltage direct current transmission (HVDC), the optical switching of thyristors is set to occupy an important position within the electricity supply system in Germany. The particular benefit of these switchable semiconductor elements lies in the fact that triggering takes place without a galvanic connection to the load circuit.... more about this project (project profile in German)

OSALED - Connecting optical sensors using light-emitting diodes

Currently, measurements of various physical and chemical quantities are generally transmitted via favourably priced electrical cables. However, transmitting sensor signals in this way becomes problematic whenever significant differences in voltage occur or whenever strong magnetic fields exist in the vicinity. One situation in which this is the case is when transmitting measurements on high-voltage equipment or when monitoring battery systems.... More about this project (project profile in German)
