SUSPENDED-FULCRUM TORQUE STANDARD MACHINE, 2ND REPORT

• Abstract:

  National Institute of Metrology (Thailand), NIMT has developed the suspended fulcrum torque standard machine. The mainly tasks are metal sheet for fulcrum and hung-weight changing. Moreover propose and investigate methods for the different lever arm length, Δl and the sensitivity of fulcrum. Experiment results that using different length of thin sheet metal besides, different evaluation techniques for Δl were compared. Sensitivity of fulcrum carried out whole measurement range was discussed. The comparison result between NIMT and PTB was expressed in term of degree of equivalence (E_n). It showed that comparison result was satisfactory.
