Development and Testing of Ring Shaped Force Transducers

Abstract

The present paper discusses the development of ring shaped force transducers. The force transducers developed have been designed on the basis of thin rings. The force transducers are developed for the nominal capacity of 100 N and in this range the ring shaped force transducers are generally not available. Hence, effort has been done for developing precision force transducers of ring shape due to simplicity of shape and ease of manufacturing. The force transducers have been calibrated according to the calibration procedure based on IS 4169-1988 (reaffirmed 2003). The uncertainty of measurement for the force transducers developed has been evaluated while taking the uncertainty components due to relative repeatability, relative interpolation, and relative zero offset etc. The results have been reported here. The approach adopted may further be extended to develop the force transducers of similar shape for lower capacity like 10N, 20N & 50N for future research work.
