- Abstract:
- The 1kg-prototype balance is a result of the technical collaboration between the Sartorius AG and the BIPM. Construction and functionality of the 8-position load alternator are based on the known BIPM FB2-technology. The 1kg-Prototype balance is constructed for highly accurate mass determination and is developed to create and maintain the national mass scale as well as the use for research and development. It permits the weighing of Pt-Ir or stainless steel masses from 100g to 1 kg as well as 1kg silicon spheres or buoyancy artifacts. The complete measurement device is installed inside an enclosed airtight aluminum chamber which can be evacuated to primary vacuum. The load alternator can be loaded comfortably through a quick load-lock device. Additional standard vacuum flanges are freely available for measuring sensors, control purposes and electronic or other connectors. The control unit running the control software allows flexible and easy programming of the required measuring sequences. Routine matter mass calibration as well as complex weighing series could be done. A detailed description of the technical and metrological parameters and possible applications are given. The function of the load alternator and the load-lock device is depicted.
