Zusammenfassung: | The invention relates to the technical field of sensor calibration, in particular to a magnetostrictive sensor calibration method and device. Due to the fact that the requirement for liquid level detection in the spinning process is high, the magnetostrictive sensor needs to be calibrated before being used to eliminate errors of the magnetostrictive sensor as much as possible. In the calibration process, the theoretical liquid level height change is calculated through water pumping, weighing and conversion, then the theoretical liquid level height change is compared with a numerical value actually measured by the magnetostrictive sensor, so that the error value of the magnetostrictive sensor is obtained, the measurement range of the magnetostrictive sensor is divided into a plurality of measurement sections, and the measurement accuracy of the magnetostrictive sensor is improved. Each measurement section has a corresponding error value, and the error values are concentrated to generate an error library, so th |
