Sensor e.g. temperature sensor, output value determining method for automation engineering, involves determining value of output parameter from another value of input parameter by interpolation of two points of points set

摘要

The method involves providing a non-linear characteristic of a sensor (S) by a points set of points, and producing another points set of the characteristic with additional auxiliary points. The auxiliary points are obtained through adjacent points of the point sets by determining inclinations of three straight line parts (g1, g2, g3), and inclinations of two sets of auxiliary straight lines (h1, h2) are calculated. A value of an output parameter is determined from another value of an input parameter by an interpolation of two points of the latter set.
