Problems solved by technology
[0003] The basic ledgers in the existing basic management of measurement are not perfect, lack of comprehensive and systematic sorting out, and the control of the measurement process is not comprehensive enough. The current measurement management work focuses on the basic management and process tracking of the pressure gauges included in the scope of compulsory inspection. Other types of measuring instruments are neglected, and their measurement characteristics cannot be guaranteed

The invention discloses a self-calibration method for a calibration mode of a pressure sensor, which is applied to a self-calibration mode formed by a workbench, a data acquisition and comparison system and a control power supply circuit, and comprises the following steps: 1, establishing a pressure sensor ledger and performing classification management; 2, designing a pressure sensor power supply control circuit; 3, determining a pressure sensor self-calibration method and carrying out calibration; 4, collecting, comparing and analyzing data in the self-correction process; and 5, carrying out real-time data comparison and data correction of the pressure sensor. According to the invention, the self-calibration of the pressure sensor can be realized, and the newly purchased or replaced pressure sensor can be supervised, so that the basic management of the measuring instrument is improved.
Description
technical field [0001] The invention belongs to the field of measurement, in particular to a self-calibration method of a pressure sensor calibration mode. Background technique [0002] In order to implement the quality control requirements of "stable control, accurate inspection, and clean pursuit", improve the level of measurement control in the production process, and promote the transformation of measurement equipment management to measurement process control, so as to realize the integration of measurement, process, quality, energy, and safety management Deep integration. Accurate measurement is a basic task for cigarette manufacturers, and must be completed before monitoring and controlling product quality. As a measuring instrument, the pressure sensor should be able to ensure the reliability, accuracy and stability of its measurement, and play an active role in process control of process quality, safety management, energy saving and emission reduction management, et...
