A Study of the Long Term Stability of Force Transducers

Abstract:This paper discusses the long term stability, over a period of more than 10 years, of force transducers with capacities ranging from 10 kN to 500 kN. The force transducers have been calibrated using force standards machines of various capacities, and are used to maintain the traceability of force measurements; from the force standard machines, to the force calibrating machines, and finally to industrial users. The study reveals that the deviation of the average values of force transducers has been varying appreciably over time. The discussion that follows identifies the probable sources of the deviations.
