The question about the system is a question about the systematics and requirements. Fiber optic applications are not only super-modern, but also unbeatably versatile. Research and development on this measurement system has been ongoing since the 1980s, and GGB has been involved from the beginning. Two basic application methods are available, which can now be combined with each other.
can be combined.
The following measuring systems are currently available through us and via us:
Braggitter, Brillouin, Raman, FabriPerriot and Doering.
Fiber optics, the current measurement medium, is not only known as the medium used everywhere for the fastest and interference-free data transmission in physical networks. It is not only the supply basis of our Internet as well as the most important component of the data infrastructure in all digitally set up and networked countries, but also a technology of the future whose highly developed existence we make use of in an astonishing way in geo- and construction measurement technology.
Fiber optic networks are virtually unaffected in terms of the quality of their function and are designed and resistant to aging for many decades, if not centuries. Thus, the digital fiber optic networking of our country continues its unbroken fast and progressive course and will largely replace all analog cable-bound technologies in the future. Because it is predestined for this.
Glass fiber has a high strength, consists of quartz glass and thus also elements that are available and degradable everywhere and thus independent of current raw material speculation and price fluctuations on the world market. As is the case with copper, for example. - and therefore calculably favorable over a long period of time.
The production of quartz glass can be described as sustainable, since the associated energy can be used from renewable sources and it is fully recyclable. The demand for fiber optic cables is insatiable and is recognized in the engineering community as a future technology and part of extended research efforts.
Surprisingly, glass is not a solid, but physically corresponds to the aggregate state of a liquid and also follows the corresponding laws.
Its astonishing strength is followed by an even more unbelievable elongation capacity of up to 6% elongation at break (specific) and is excellently suited for use in static components, whose deformation in this order of magnitude is already equivalent to destruction.
So almost everywhere where a measuring range of 3% strain is to be expected.
Their only weakness is the transverse stress and thus the force application transverse to the fiber direction, which must lead to special protective measures, since the strong but brittle material tends to break the fiber with corresponding force application. However, with expert knowledge, something can be done about this and protective measures can be introduced in the application. - If you know what you are doing.
This is where the craft of construction measurement technology comes into play again, which must be applicable from experience and knowledge of what is required in the construction industry. Not an unsolvable problem, but a sensitive task that not every company or educational institution can do just like that and as a matter of course.
Metrology in construction is a small and manageable industry, the importance of which has not yet been recognized and appreciated, but in the wake of increasingly structural weaknesses and hardly predictable dynamic loads are rarely studied in depth, since execution and the choice of construction material used can vary greatly according to the requirements of the structure.
This has been taken care of by companies that have experimented more than they have actually performed. This does not help the reputation of a technology to which we have been committed for over 30 years.
So much so that, to this day, one has to orient oneself almost exclusively to parameters and theoretical assumptions that serve a static calculation.
Once the construction industry is aware of its responsibility and position in the world market and is considered on an equal footing with industrial construction such as aircraft or ship building, and similar quality standards exist, the use of this measurement technology will very quickly be recognized as the standard. Especially since the information content can hardly be surpassed.
In these engineering fields, no one is discussing the need for fiber optic measurement solutions, where they have been used for decades and serve to meet high safety standards.
So it is time for a rethink and modernization of an industry, especially since area-wide recording of conditions instead of using disparate theoretical FE calculation methods has become an urgent need for reorientation. At some point, the construction industry will have to follow this lead, even if it has been comfortably resisted to date. Why ever.
With the GGB you can go this step and forthcoming way and book success by positive experiences, which will promote also your quality consciousness.
