Für die Überwachung von Anlagen und für den Gesundheitsschutz ist der Einsatz von Gassensoren und deren Kalibrierung von zunehmender Bedeutung. Beispielsweise werden zur Vermeidung von Virusübertragungen CO₂-Sensoren zur Überwachung der Luftqualität eingesetzt. Zur Kalibrierung dieser Sensoren werden Prüfgasgemische benötigt, bei denen der Anteil der relevanten Komponente – insbesondere im Bereich von 400 ppm bis 2000 ppm – dynamisch eingestellt werden kann. Ein innovatives Verfahren aus der PTB nutzt hierfür eine Vorrichtung zur Mischung eines Matrixgases und eines Zumischgases mithilfe Regelungvon kritisch betriebenen Düsen. Dabei wird das Mischungsverhältnis eines binären Prüf- oder Kalibriergases nur anhand von Druckmessungen an zwei Düsen bestimmt. (Technologieangebot 546)

In der PTB wurde die Oberflächengröße eines lebensgroßen Kuhmodells ermittelt. Damit wurden die Erfahrungen bei der dimensionellen Vermessung von natürlichem bzw. naturnahem Material erweitert, was zukünftigen metrologischen Herausforderungen zugutekommt.

Research topics

The SI with its 7 base units — In the new International System of Units (SI), seven fundamental constants are determined as defining reference values. (Diagram: PTB)

An overview of the diverse research landscape of PTB as well as some particularly highlighted topics (for example, PTB research surrounding the International System of Units SI) you will find in the chapter Opens internal link in current window Research & Development). In addition, it is always worthwhile to look at the main Homepage as well as the homepages of the respective Divisions. How reputable PTB is among researchers you can see at PTB in the World of Research. Furthermore, PTB has been – specifically its R&D component, in particular – evaluated repeatedly with excellent results. You can download the respective documents (which are in German only) in the right column as a pdf file.

Scientific publications

In the database Opens internal link in current window PTB-Publica you can search for scientific publications by PTB staff members. Furthermore, some divisions maintain their own overview lists on the publications of their staff members. These you will find via the respective homepages of the divisions.

Research collaborations

The many collaborations of the individual PTB divisions you will find in the Annual Report under the column Opens internal link in current window From the Divisions. International collaborations of PTB, e.g. with other metrology institutes within the framework of the European Metrology Programme for Innovation and Research EMPIR, you will find at International Affairs. Some current EMPIR dates you will find in the current issue of Opens internal link in current window PTB-News.

What PTB offers doctoral candidates

PTB's broad range of offers for students, doctoral candidates, and also extending beyond the doctorate degree you will find in the chapter Opens internal link in current window About Us & Careers.
