Manufacturing loadcells since 1972
Engineering Application Sheet E013 - High Temperature Loadcell Output And Creep
High temperature specification loadcells do not behave like the more familiar standard temperature range loadcells. Due to the materials employed in the construction of high temperature circuits the output signal can suffer from twice the normal level of creep. This means that static measurements need to adopt a timed measurement technique. Dynamic or non-zero referenced measurement is not affected.
1. Dynamic Measurement
Force inputs changing with time are immune to the effects of loadcell creep. Peak to peak or transient waveforms by virtue of their ever-changing magnitude do not suffer from time dependant errors such as creep.
