A New 500 Kg Dead-Weight Machine for Test Load Cell According to OIML R60 and Performance Tests Realised by UME

摘要

In order to test load cells used according to OIML R60 regulation in different temperature such as –10, 20 and 40°C with increasing and decreasing loading conditions, dead-weight machine and good temperature control cabinet are necessary. ESIT Company has been manufacturing different type and capacities load cells in the last 12 years in Istanbul. In order to improve product quality and accuracy of ESIT load cells, a new dead-weight machine was designed and manufactured in ESIT Factory. This machine is capable to testing the compression load cells up to 500 kg. In this machine, quick loading and unloading for creep test purposes is realized by newly developed lever arm mechanism. Since temperature control cabinet restricts the movement of load cells up and down, this mechanism was developed to move loading frame of machine. UME Mass Laboratory calibrated to each dead weight. UME Force Laboratory realized a performance test of this machine using UME transfer force transducer.
