The invention can provide continuous and stable air pressure and convert the calibration data of the pressure measurement and control instrument into the P-V-C data tables.

Description

technical field [0001] The invention relates to the technical field of pressure calibration and measurement and control, in particular to a device for converting pressure calibration data into a data table. Background technique [0002] Pressure measuring equipment must be calibrated periodically to ensure accurate pressure measurement. The pressure calibration source is a special instrument for calibrating pressure measurement equipment. Generally, the accuracy of the pressure calibration source is an order of magnitude higher than that of the pressure measurement equipment. With the development of pressure calibration and measurement and control technology, the pressure measurement and control instrument has replaced the traditional pressure calibration source and realized automatic control of pressure calibration data output, data measurement, data processing and calibration of pressure measurement equipment and other functions. The pressure measuring and controlling ins...
