The magnet system is an essential component of the Kibble balance, a device that is used to
realize the unit of mass. It is the source of the magnetic flux, and its importance is captured in …

After several years of development and continuous improvement of the BIPM Kibble
balance, mass measurement of a 1 kg Pt/Ir artefact in terms of the Planck constant has been …

The Kibble balance is expected to become an important instrument in the near future for
realizing the unit of mass, the kilogram, in the revised international system of units (SI). The …

A high-precision current source, capable of supporting weighing measurements with a
relative uncertainty at the level, is essential for Kibble balance experiments. However, most …

Although the so-called magnetic geometrical factor, Bl, of a Kibble balance does not appear
in the Kibble equations, it offers the precision link between electrical and mechanical …

The Kibble balance has become one of the major instruments for realizing the mass unit, the
kilogram, in the revised international system of units (SI). Researchers at about a dozen …

Permanent magnets together with yokes to concentrate the magnetic flux into a cylindrical
air gap are widely employed in Kibble balances. These experiments require a uniform …

The design of the permanent magnet system for the new quantum electromechanical
metrology suite (QEMMS) is described. The QEMMS, developed at the National Institute of …

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 …

The force transducer converts the magnitude of a force into an associated electrical signal,
detecting mechanical quantities such as tension, pressure, weight, torque, strain, and …
