Design of a Miniature Kibble Balance for Kilogram-Scale Mass Calibration -- KBmini
Shisong Li, Nanjia Li, Weibo Liu +3
Tabletop version Kibble balances are a significant developing trend for mass realizations following the revised International System of Units. A key innovation through the miniatur…
Self-Error Correcting Method for Magnetic-Array-Type Current Sensors in Multi-Core Cable Applications
Xiaohu Liu, Keyu Hou, Kang Ma +7
Data-driven methods enable online assessment of error states in magnetic-array-type current sensors, and long-term measurement stability can be enhanced through further self-error…
An Approach for Restoring Magnetic Field Uniformity in Openable BIPM-Type Kibble Balance Magnets
Nanjia Li, Weibo Liu, Yongchao Ma +3
The Kibble balance realizes the kilogram by linking mechanical and electrical quantities via a magnet system. In an improved BIPM-type magnet design by Tsinghua University, an open…
An Evaluation of External Magnetic Flux Error in Magnet-Moving Kibble balances
Yongchao Ma, Wei Zhao, Songling Huang +1
The magnet-moving measurement scheme in Kibble balances avoids displacing force-sensitive components, such as the weighing cell, and enables a broader magnetic profile measurement…
Precision Control of Resistive Power in Kibble Balance Coils: An Advanced Method for Minimizing Temperature-Related Magnetic Errors
Weibo Liu, Stephan Schlamminger, Shisong Li
Temperature changes affect the coercivity of permanent magnets, thereby impacting the factor and potentially introducing systematic errors in Kibble balance measurements. Whil…
Updates on the Tsinghua Tabletop Kibble Balance
Shisong Li, Yongchao Ma, Kang Ma +7
With the adoption of the revised International System of Units (SI), the Kibble balance has become a pivotal instrument for mass calibrations against the Planck constant, . One…
