Die Physikalisch-Technische Bundesanstalt (PTB) entwickelt gemeinsam mit der Technischen Universität Ilmenau eine sogenannte Planck-Waage. Sie arbeitet nach dem Prinzip der elektromagnetischen Kraftkompensation: Eine Gewichtskraft auf der einen Seite der Waage wird durch eine elektromagnetische Kraft auf der anderen Seite ausgeglichen. Gewichtsstücke, sogenannte Masse-Normale, die Waagen bisher „sagen“, wie groß die Masse auf der Waage tatsächlich ist (z. B. 1 kg), werden dann nicht mehr benötigt. Ende des Jahres soll den Wissenschaftlern ein erster Prototyp der Planck-Waage zur Verfügung stehen. Damit kann geprüft werden, welche Entwicklungsschritte noch nötig sind, um die Waage für den industriellen Einsatz tauglich zu machen. Dies könnte der Startschuss für die Entwicklung einer ganz neuen, industrietauglichen Waagengeneration sein.

Since 1 May 2017, the Physikalisch-Technische Bundesanstalt has operated a new Core Facility, called "Metrology of Ultra-Low Magnetic Fields", at its site in Berlin-Charlottenburg. Funded by the Deutsche Forschungsgemeinschaft (DFG), PTB allows external scientists from universities, from international metrology institutes and from companies to access its know-how and its range of instruments for the measurement of ultra-low magnetic fields – instruments that are unique throughout the world.

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 windowResearch & Development). In addition, it is always worthwhile to look at the Opens internal link in current windowmain Homepage as well as the homepages of the respective Opens internal link in current windowDivisions. How reputable PTB is among researchers you can see at Opens internal link in current windowPTB 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 windowPTB-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 Opens internal link in current windowhomepages 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 windowFrom the Divisions. International collaborations of PTB, e.g. with other metrology institutes within the framework of the European Metrology Research Programme EMRP/EMPIR, you will find at Opens internal link in current windowInternational Affairs. Some current EMRP dates you will find in the current issue of Opens internal link in current windowPTB-News.
