Development of Kibble balance for primary realization of Massa

Reference number 2018-04604
Coordinator RISE Research Institutes of Sweden AB - RISE Mätteknik, Borås
Funding from Vinnova SEK 900 000
Project duration January 2019 - December 2021
Status Ongoing

Purpose and goal

The project aims at developing, within the framework of international cooperation supervised by NPL, developing and constructing a Kibble Balance, which will be placed at Riksmätplatsen after project termination in order to perform traceable mass measurements based on the new SI definitions. The Kibble Balance will also be used for future research and development in the area and will be an extremely important instrument for raising the competence in Sweden´s primary metrology.

Expected results and effects

- Build a demonstrator that verifies the principles and test various improvements. - In 2020, another demonstrator will be built in the size and performance of the final production. In parallel, metrological methods and tests for interference resistance are developed. - Production of at least one system for each participating NMI i.e. 6 units or more. Metrological methods for using the weights of the respective NMI are completed. - Spread of competence to industry and society through numerous scientific and popular scientific publications.

Planned approach and implementation

1. The first prototype is developed and completed in 2019. Tests of, for example, EMC and temperature sensitivity are performed. 2. The first Kibble Balance of final design and performance will be completed in 2020. 3. The production of a Kibble Balance to each participating NMI will be completed in 2021 as well as the parallel developed metrological methods. 4. Throughout the project period, reporting, both scientific and popular science, will take place continuously.
