Abstract

The proposed paper relates to an electronically scanned white-light interferometric transducer for high-pressure measurements which consists of a sensor, a conditioning circuit, an analog-to-digital converter and a digital signal processor executing preprocessing of the output signal from the sensor. The calibration of such a transducer consists in identifying a function modeling the relationship between the raw result of measurement y, being the output of the transducer, and the measured pressure p, taking into account an influence quantity temperature T. An algorithm for calibration is proposed and studied
