What is the best calibration method for very non-linear data?
The 793 software supports linearization models, Gain/Delta K, Gain/Linearization, or Gain/Advanced Linearization.
Gain/Advanced Linearization is the best method for very non-linear data. Below are comparisons of the LVDT calibration error before Linearization (top) and after using Gain/Linearization (middle) and Gain/Advanced Linearization (bottom).
Gain/Advanced Linearization Requirements:
494 electronics only
494.16, 494.25, 494.26 DUC’s only
494.21 DUC excluded
793 software version 5.5 and later
