| Zusammenfassung | We propose a self-calibrating balance, which allows the calibration of weights in a continuous range from 1 mg to 1 kg. This so-called Planck-Balance (PB) is similar to the physical approach of Kibble Balances that allow the mass to be derived from the Planck constant. Using the Planck-Balance no calibrated mass standards are required during weighing processes any longer, because all measurements are traceable to the electrical quantities and the Planck constant. This allows a new approach of balance types after the expected redefinition of the SI-units by end of 2018. In contrast to many scientific oriented developments, the PB is focused on industrial use. Therefore, two balances will be developed, a PB2 and a PB1, which will allow a relative measurement uncertainty (k = 2) of 5.3 × 10-7 and 1.7 × 10-7, respectively. Those aimed accuracies refer to the class E2 and E1 weights, as specified in OIML R 111-1. The balances will be developed in a cooperation of the PTB and TU Ilmenau in a project funded by the German Federal Ministry of Education and Research. The project started in January 2017 and will run for 3 years. |
