Research, Development and Characterization of a Build-up System Prototype up to 600 kN

摘要

This paper describes the research, development, construction, validation tests and metrological characterization of a Force Transducers Pyramid prototype (Build-Up System), in the nominal range of 600 kN. This system is used for the standardization and dissemination of the physical magnitude force, propitiating the utilization of alternative system for calibration of force measurement instruments, such as: force transducers, load cells, proving rings and scales of testing machines. In its construction three force transducers, in the nominal range of 200 kN were used, individually calibrated and later together. In its characterization, a force standardization machine in the nominal range of 1000 kN and a hydraulic force generating machine of 1000 kN were used, both installed in the Force and Hardness Laboratory (LAFOR), of the National Institute of Metrology, Standardization and Industrial Quality (INMETRO). By this way it is intended to transfer and to implant this technology widely spread abroad, to the Brazilian metrological force measurement field.
