| Abstract: | The concentration measurement instrument of carb on monoxide based on spectrum infrared absorption theory consists of detector sy stem, signal amplifying and controlling system, display and warning system. In d etail, the detector system is mainly composed of plane light source, infrared wi ndows, gas path, sampling pump, chopper, narrow-band filter and infrared detect or. The signal amplifying and controlling system is mainly composed of voltage f ollower amplifier, selective frequency amplifier, shaping amplifier, sampling ho ld circuit, multi-channel-simulated switch, A/D converter and 8031 chip proces sor. And the display and warning system is mainly composed of indicator, printer , acoustic warning apparatus and I/O circuit. The principle, the structure and t he main specification of the instrument are presented. The key technologies and its corresponding solution methods are discussed. |
