Performance evaluation of force transducers

Abstract

The performance evaluation of the developed ring shaped force transducers of capacity 20 and 50 kN for tension and compression modes has been studied. The force transducers have been metrologically characterized according to the calibration procedures based on the standards ISO 376-2004 and IS 4169-1988 (reaffirmed 2003). The factors contributing to the uncertainty of the force transducers and methodology for computing the uncertainty of force transducers have been discussed. The 50 kN dead weight force machine with uncertainty of force applied (best measurement capability, bmc) ± 0.003% (<i style="">k </i>= 2) has been used for metrological characterization of force transducers. The force transducers qualify the class 00 per the standard ISO 376-2004 and class 0 as per IS 4169-1988 (reaffirmed 2003), hence, may be used as force transfer standards.
