Correction method for force transducers on dynamic condition with or without the Levitation Mass Method (LMM)

AbstractIn this paper, calibration method for force transducers on dynamic force condition with or without the levitation mass method (LMM) is reviewed. At first, a brief review of the LMM is described. Secondly, a correction method for force transducer in dynamic force measurement using the LMM is introduced. Finally, the self-correction method for force transducer is shown with results. The most of the dynamic error of an S-shaped strain gauge transducer is effect of inertial mass of the transducer. By using the LMM, the relations between the dynamic error and transducer's output are investigated and a correction parameter is calculated. Without the LMM, the force measured by the transducer can be corrected by use of the correction parameter
