OPERATION OF A NEW FORCE STANDARD MACHINE AT HELLENIC INSTITUTE OF METROLOGY

• Abstract:

  The following paper gives a detailed overview of the characteristics of the new state-of-the-art force standard machine commissioned in July/August 2000 at site of the Hellenic Institute of Metrology by the manufacturing company GTM. The fully automated force standard facility is a combined dead weight - lever amplification machine with 110 kN direct load capacity and a 10:1 lever multiplication part and is to be the National Force Standard of Greece. The 110 kN dead weight section is equipped with a mass stack of nickel-plated steel weights realising discrete forces in compression and tension mode. The forces are applied in 10 % steps up to 110 % of usual nominal loads of transducers starting with 1 kN. Comparison measurements were carried out with five precision force transfer standards with capacities of 10 kN, 50 kN, 100 kN, 500 kN and 1 MN, all of which were initially calibrated at PTB. Effects of parasitic components on the lever system were submitted to a careful examination. The results of tests to determine the performance of the force standard machine are discussed in detail.
