METHOD FOR CALIBRATING MEASURING TRANSDUCERS INCORPORATING INTEGRATED SENSING ELEMENT Russian patent published in 2004 - IPC

FIELD: measurement technology. SUBSTANCE: method includes discrimination of main and additional measuring channels in transducer corresponding to measured and affecting input quantities, measurement of output quantities at different combinations of input quantities. generation of transducer mathematical model using results of experiment, and evaluation of input quantities. Novelty is that parameters of transducer mathematical model expressed in factors approximating polynomia of measuring channels are found from values of input and output quantities of main channels and those of output quantities of additional channels. Values of quantities being measured are found from parameters of mathematical model and from values of all output quantities of transducer. Mathematical model parameters can be found using least square criterion. EFFECT: facilitated procedure due to dispensing with stabilization and measurement of affecting factors to find input self-explanatory quantities. 2 cl, 1 dwg, 1 tbl
