In the work under study, the main functions of intelligent measuring instruments are considered. To increase the calibration and verification interval, it is proposed to implement the self-calibration function in the sensor. The methods of calibration of measuring instruments are analyzed. A method for self-calibration of intelligent measuring instruments using the redundant method has been developed. To correct external and internal influences, two primary transducers of the same type were used for differential measurement. A significant advantage of the proposed method is that the sensor can independently introduce a correction to the measured signal, taking into account the calibration data.
