The new METAS Watt Balance, Mark II
نویسندگان
چکیده
In the context of the future new definition of the mass unit, kg, a promising route to link the mass unit to a fundamental constant, the Planck constant h, is represented by the watt balance experiment. Since a number of years, the Federal Institute of Metrology is active in this field and published a first result with its Mark I experiment in 2011. To reach the target uncertainty of 2 parts in 10, the Mark II METAS watt balance is being developed. In this paper, the different modules of the experiment are presented and their respective metrological requirements and experimental behaviour are discussed.

Design of the new METAS watt balance experiment Mark II
The kilogram is the last unit of the international system of units (SI) still based on a material artefact, the international prototype of the kilogram (IPK). The comparisons made in the last hundred years have clearly revealed a long-term relative drift between the IPK and the official copies kept under similar conditions at the Bureau International des Poids et Mesures. A promising route towa...
متن کاملThe New Watt Balance Experiment at Metas
The kilogram is the last unit of the international system (SI) still based on a material artifact, the international prototype of the kilogram (IPK). The comparisons made in the last hundred years have clearly revealed a long term relative drift between the IPK and a set of copies kept under similar conditions. Since the long term stability is one of the major conditions set on the SI base unit...
متن کاملDetermination of the Planck constant with the METAS watt balance
The METAS watt balance project was initiated slightly more than a decade ago. Over this time, the apparatus has been through an uninterrupted series of upgrades that have improved its reliability to a point where continuous series of measurements can be taken fully automatically over periods of several months. A comprehensive analysis of possible systematic errors has now been completed and a l...
متن کاملThe watt or Kibble balance: a technique for implementing the new SI definition of the unit of mass
The redefinition of the SI unit of mass in terms of a fixed value of the Planck constant has been made possible by the Kibble balance, previously known as the watt balance. Once the new definition has been adopted, the Kibble balance technique will permit the realisation of the mass unit over a range from milligrams to kilograms. We describe the theory underlying the Kibble balance and practica...
متن کاملA Safety-II Perspective on Organisational Learning in Healthcare Organisations; Comment on “False Dawns and New Horizons in Patient Safety Research and Practice”
In their recent editorial Mannion and Braithwaite provide an insightful critique of traditional patient safety improvement efforts, and offer a powerful alternative vision based on Safety-II thinking that has the potential to radically transform the way we approach patient safety. In this commentary, I explore how the Safety-II perspective points to new directions for organisational learning in...
