ABSTRACT:
A method of error compensation for transducers having non-linear characteristics is shown. A computer-supported measuring circuit is used. In a first factory alignment, the output characteristic of the transducer is set so that it can be linearized by the computer using a power function. The appropriate exponent of the power function is stored. At the place of use, at least three calibration measurements are performed with the installed transducer using defined calibration measured values substantially spanning the measuring range of the transducer equidistantly. The power function is solved with the calibration measuring results and the stored exponent, so that the constants not yet known can be calculated. During every following service measurement, the actual measuring result is put into the now solved power function. The result of the equation is then outputted as the error-compensated measuring result.
