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, &Delta;<i>l</i> and the sensitivity of fulcrum. Experiment results that using different length of thin sheet metal besides, different evaluation techniques for &Delta;<i>l</i> 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 (<i>E</i>_n). It showed that comparison result was satisfactory.
