ABSTRACT:
A processor is described for monitoring a sensor whose output signal follows a nonlinear curve in response to a linear change in a monitored phenomenon. The processor converts the sensor signal to a linear output proportional or equal to the phenomenon being monitored. The processor includes a memory for storing a table which includes a starting data point value S on the curve, a starting slope value S' to another data point on the curve, a starting curvature value S" for a succession of the data points on the curve and a plurality of rate of change of curvature values S'" for the curve. The values of S'" for a first region of the curve are calculated based on an initial output signal interval between data point values. The values of S'" for each succeeding region of the curve are based on increasing, by a preselected factor, the signal interval between data point values. The processor includes a calculation device for computing repeated aditons of the S', S", S'" values. An addition occurs when the sensor output signal rises above a predetermined signal interval value between data points. The processor also includes a controller which increases, by a preselected factor, the predetermined sensor signal interval value each time the output signal enters a succeeding region of the curve. Thus, as the data points move up the curve, they become increasingly farther apart, but accuracy does not suffer as such data points reside on the more regular (steady curvature, for instance) regions of the curve. Data storage requirements are thus minimized.
