Abstract

The creep and creep recovery are important characteristics of force transducers. Thus, this study is focused on the measurements of creep and creep recovery for transducers of different capacities. <br />Creep measurements are carried out according to three different loading schemes, revealed that the creep values measured at maximum loads and reached after time intervals from 30 to 300 seconds like proposed in a new draft of ISO 376 from the moment of load application. The effect was higher in direct loading (one step to reach the maximum load) than those obtained from the two other schemes (chosen loading steps distributed all over the full range up to maximum load and according to automatic machine calibration (M/C) software that designed to cover all the range up to maximum load). Effect of creep on hysteresis value is also investigated.
