1. A measuring system for determining a value of a measured parameter M, comprising:

  • sensor means for supplying an electrical measuring signal S having a value which is dependent on a value of the measured parameter M;

    control means connected to receive said measured signal S from said sensor means, said control means having a type characteristic memory containing a definition of a type characteristic curve, points of the type characteristic curve defining particular values of parameter M corresponding to particular values for measured signal S, said definition of said type characteristic curve being based on an average of individual characteristic curves of a plurality of sensor means of a same type as the sensor means connected to the control means, each of said individual characteristic curves defining values of signal S for corresponding values of parameter M for each of the plurality of sensor means;

    said sensor means connected to the control means including a coding memory means containing data for defining as individual characteristic curve of the connected sensor means;

    said control means including means for defining said individual characteristic curve of the connected sensor means by use of said data from the coding memory means and said points defining the type characteristic curve, and including memory means for storing the defined individual characteristic curve; and

    said control means determining from the defined individual characteristic curve of the connected sensor an output value X corresponding to a measured value S input to the control means.
