The Planck-Balance is a new weighing instrument, that utilizes the Kibble principle for mass measurements. In contrast to existing Kibble experiments the balance is aimed at applications in industrial or research use. The proposed new definition of the kilogram with a fixed value of the Planck constant will allow primary mass measurements with electrical measurements using the Kibble principle. Two instruments, PB2 and PB1 will be developed in a joint research project of the Physikalisch-Technische Bundesanstalt (PTB) and the Technische Universität Ilmenau, funded by the German Federal Ministry of Education and Research. The aimed measurement range is from 1 mg to 100 g and 1 mg to 1 kg with a relative measurement uncertainty according to E2 and E1 accuracy classes, respectively, as specified in OIML R 111-1. For the determination of the measurement uncertainty a virtual Planck-Balance will be set up, that uses Monte Carlo simulation to determine measurement uncertainties during the measurement process.
