Abstract

System to linealize a non-linear output of a sensor, it comprises a processor to monitor a sensor whose output signal continues a non-linear curve in response to a linear variation in a monitored phenomenon, that converts the sensor signal in a proportional linear output or equal to the phenomenon that is being monitored, and includes a memory to store a table, which includes a value d of point of point of data in the curve, a value s of departure of pending to another point of data in the curve, a value s "of curvature departure for a succession of the data points in the curve and a plurality of values" s "of variation speed of the curvature for the initial output curve between values of points of data or their application to storage of data of physical parameters.
