GRADUATION AND MATHEMATICAL PROCESSING OF MEASURING DATA PIEZOSENSORSOF CONTROL OF MECHANICAL PRESSURE IN FIRM CONTINUOUS ENVIRONMENTSV. ZUBZOV, А. YAGUBKIN, Е. ZUBZOVAReal function of transformation of the gage will be nonlinear. The physical sense of this nonlinearityconsists in change of sensitivity of the gage at change of the measured size. For an estimation of errors of thegage connected with nonlinearity of its transformation, most often use approximation of real function oftransformation by a straight line piece. Thus the problem of carrying out of an approximating straight linethrough a number of experimental points can be successfully solved, for example, a method of the least squares.On the received experimental data defined average values of target size at stressing and destressing. This datathen used for calculation of errors of gages concerning approximating function of linear dependence whichincludes the valid values of physical size. Differently, on experimental values of entrance and target sizes pay offsensitivity of the gage And, representing a tangent of angle of an inclination of an approximating straight line to
