Self-calibration of intelligent measurements using the redundant method

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.
