| Summary, etc. |
A NIS 1 kN·m secondary standard torque calibration machine designed earlier [1] is further developed to be a primary standard torque calibration machine. Design and construction of a lever-mass system with ends to be coaxial with the transducer axis are implemented. FEM analysis is used to check the mechanical stresses occurring in the critical components affecting the deflection in the designed lever arm. Procedures for accurate measurements torque arm are described. Expected relative expanded uncertainty is worked out to be 2·10-4. A study on the effect of relative humidity and temperature on the DMP40 measuring amplifier and the BN100A bridge calibration unit as one of the main sources of torque machine uncertainty is reported. Furthermore, the effect of relative humidity on the zero signal of torque transducers is investigated. Finally a study of the influence of temperature and relative humidity on the sensitivity and the characteristics of torque transducers such as residual zero torque, reversibility and creep, is presented. Equations are presented to predict the effect of temperature/relative humidity changes on the sensitivity of torque transducers |
