A general digital linearising method for transducers
W T Bolk · Journal of Physics E Scientific Instruments · 1985
A practical three-point interpolation algorithm is presented which corrects for manufacturing tolerances, zero offset, scaling errors and nonlinearity of transducers and signal conditioners. The algorithm is applicable to data-acquisition systems which make use of a microprocessor. Each measuring channel requires three parameters. One simple universal routine using these parameters calculates the value of each measurand. Results are given for eight temperature transducers.
