Validity of Extrapolation Based on Polynomial Approximations

• Abstract:

  This paper describes a method to find an appropriate extrapolation with its corresponding uncertainty for any sensor in its full working range with the information provided by calibrations in partial ranges lower than the full working range. It is based on the assumption that the relation between the sensor input and output can be described by means of polynomial approximations. The method includes several conditions that are established in order to ensure a valid approximation for the extrapolation. The work is a contribution to the EMRP project “Force traceability within the meganewton range”.
