| Abstract: | A fully automatic calibration system for pressure gauges with pointers is presented in this paper, in- cluding an automatic generating system of standard pressure and an automatic reading system of pointer readings. High calibration speed and efficiency can be achieved with the use of this system, which is suitable for automatic calibration of pressure gauges with spans of 0-16MPa and precision of 0.4 degree. It will play an impor tant role in remedying the present state of pressure calibration and fulfilling automatic calibration of pressure gauges. |
