Background technology

High-pressure gas pressure pressure instrumentation is widely used in defence and military system, the measurement range of pressure sensor used The upper limit reaches more than 70MPa.Pressure is high, dangerous big, to the standard of high-pressure gas pressure sensor measurement data during experiment True property requirement is very high, is related to type product quality.Therefore, it is necessary to essence is carried out to used high-pressure gas pressure sensor True calibration.The field calibration demand of the high-pressure gas pressure instrument of model experiment in recent years is more and more.But this method is deposited In problems:

(1) dismounting, due to the limitation of environmental condition, influences measurement data accuracy to laboratory investment;

(2) dismounting easily damages the hickey of manometer, influences equipment use;

(3) high-pressure gas pressure sensor can only be calibrated, it is impossible to which the high-pressure gas pressure including acquisition system is surveyed Amount system is calibrated;

(4) the laboratory investment cycle is longer, influences unit use.

Due to these shortcomings, there is an urgent need to innovate calibration method, carry out field calibration.

The content of the invention

It is an object of the invention to:A kind of high-pressure gas pressure field calibration method is provided, solves puzzlement gases at high pressure pressure Power calibrating indicating instrument and the problem used ensure under site environment, the accuracy of high-pressure gas pressure instrument measurement data.
