There are several types of simple Accepted 20 July 2015 shaped force transducers which may range from ring shaped force transducers to cantilever Available online type or beam type force transducers. Ring shaped force transducers are one of most commonly 21 July 2015 Keywords used type of force transducers are developed on the basis of theory of thin rings. Till today Force transducers some of the modifications of ring shaped force transducers have been reported the present Elliptical shaped transducer investigation discusses the development of elliptical shaped force transducer as a modification Dead Weight Force Machine of ring shaped force transducers and its preliminary investigation on metrological characterization based on the calibration procedures according to standards ISO 376-2011. The force transducer has been developed for the nominal capacity of 20 kN and strain gauges have been applied over the optimum locations to minimize cross sensitivity. The force transducer is developed exclusively for static force measurement related applications to serve
