Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a pressure transmitter calibration system based on LabVIEW. Background technique [0002] Pressure transmitters are important instruments for detecting air pressure and hydraulic pressure. Newly developed or newly manufactured pressure transmitters cannot be immediately applied to actual engineering tests. Before use, it is necessary to carry out a series of comprehensive technical performance calibration experiments on the original design indicators to determine the actual performance of the instrument. Some indicators (such as sensitivity, etc.) of long-term pressure transmitters may change, and retest calibration is also required, and the original data can only be used after correction. The quality of the calibration results directly affects the data error of the actual test. Therefore, the calibration of the pressure transmitter before use is particularly important. [0003...
