Ongoing digitalization in metrology and the ever-growing complexity of measurement systems have increased the effort required to create complex software for uncertainty estimation. To address this issue, a general structure for uncertainty estimation

In this paper we present the progress in development of a table-top version of the Kibble balance under the name Planck-Balance 2 (PB2). The PB2 is developed as a collaboration effort between the Technische Universität Ilmenau (TU Ilmenau) and Physi

Zusammenfassung Seit dem 20. Mai 2019 gilt das neue Internationale Einheitensystem SI. Dies stellt eine Zäsur in der Geschichte der Einheiten dar, denn von nun an sind alle 7 Basiseinheiten durch Fundamentalkonstanten definiert. Gerade für die Mass

Obwohl die Gravitationskonstante eine der ersten Fundamentalkonstanten ist, die je gemessen wurde, ist sie immer noch die am ungenauesten bestimmte. In den letzten fünf Jahren hat sich die relative Standardmessunsicherheit nur etwa um den Faktor zwe

An experiment shows that Newton’s law of gravity holds even for two masses as small as about 90 milligrams. The findings take us a step nearer to measuring gravitational fields that are so weak that they could enter the quantum regime. Newton’s l

Accurate particle mass and velocity measurement is needed for interpreting test results in erosion tests of materials and coatings. The impact and damage of a surface is influenced by the kinetic energy of a particle, i.e. particle mass and velocity.

The Planck-Balance is a table-top version of a Kibble balance. In contrast to many other Kibble balances, the coil is moved sinusoidally and an ac rather than a dc signal is generated in the velocity mode. The three-parameter sine fitting algorithm i

We report on a direct measurement of the relativistic Doppler shift with a commercial free-fall absolute gravimeter of the type FG5X. The observed Doppler shift, which is commonly called speed-of-light perturbation, can be well described by the relat
