Development on a New Type of Intelligent Vacuum Measurement Instrument

In this paper, we discuss a new type of intelligent vacuum measurement instrument controlled by single chip microcomputer with the sensor of the vacuum guage DL 5. The principle of this instrument is simply presented. the method of its realization is also described in detail. The distinguish features of this instrument are that we adopt the single ship microcomputer to control the launch electric current; so, we not only raise the measuring precision but also expound its measurement range with adding the calculation of the launch electric current. The instrument, which applied the resisting interference measure in software, has the function of self diagnosis and self protection.
