The Planck-Balance - primary mass metrology for industrial applications

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…

Investigations on motion deviations of an EMFC balance

This paper will present experiments to identify the angular misalignment and displacement of the coil movement of a commercial electromagnetic force compensated balance (EMFC) relative to the ideal trajectory. For this purpose the mechanical stability of measurement set-up and the environmental characteristics…

The virtual weight

A virtual weight is a numerical representation of a physical mass weight, describing the metrological behavior under certain measurement conditions. Based on a Monte Carlo simulation, it considers all significant influence variables with their respective uncertainty distribution. For the virtual weight…

A self-calibrating multicomponent force/torque measuring system

A multi-component self-calibrating force and torque sensor is presented. In this system, the principle of a Kibble balance is adapted for the traceable force and torque measurement in three orthogonal directions. The system has two operating modes: the velocity mode and the force/torque sensing mode.…

Magnet system for the Planck-balance

The current definition of the unit kilogram by an artifact is about to be replaced by a definition based on a fundamental constant, which is the Planck constant. To establish the link between a mass standard and the Planck constant an instrument called Watt- or Kibble-Balance can be used. This instrument…

The Planck-Balance – a self-calibrating precision balance for industrial applications

A self-calibrating balance is proposed, 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…
