Abstract

The establishment of national calibration services (NCS) and mutual agreements between the NCS of the different countries (UKAS, DKD, SIT, etc.) have increased the necessity of the dissemination of the unit of force inside the individual countries and of standards harmonisation through continuous international comparison.
In the paper the development, construction and preliminary metrological characterization of a Build-Up System (Force Transducers Pyramid Type) are described. In its construction three force transducers, in the nominal range of 1000 kN were used, individually calibrated and later together. Results are given concerning: the evaluation of repeatability, linearity, rotation effect and hysteresis.
