Fully automatic mass laboratory from 1 mg up to 50 kg – Robots perform high precision mass determination

Abstract

In order to meet the requirements for a state-of-the-art metrology institute and in an endeavour to build a fully automatic mass laboratory, the Austrian Federal Office of Metrology and Surveying (BEV) has developed and realized in cooperation with Sartorius AG in Goettingen and the Vienna University of Technology three different handling systems for automatic testing weights on high-precision mass comparators.<br /> Fully automatic System for alternating weights on mass comparators with different weighing capacity have been realized; one from 1 mg up to 10 g, one from 10 g up to 1 kg an the third one from 1 kg up to 20 (50) kg using two comparators. The resulting load alternator "robot" holds between ten and eighty test weights and a corresponding number of reference Standard weights. All weights are transported without pallets. The Systems are based on Computer control and linear drive trains, and are used at the BEV to disseminate mass and for the calibration and verification of weights.
