zrf 4 in case of carbon monoxide measurement, a high perform- ance converter is provided to convert carbon monoxide into carbon dioxide. here, the carbon monoxide is eliminated and the gas is led into one cell of the high-sensitivity infrared analyzer. in the othe flow path, the gas is led directly into the other cell of the analyzer. the output of analyzer varies with the difference of the concentration of the carbon monoxide between two cells, eliminating the effects of interfering components. moreover, zero calibration can be held without zero stan- dard gas, flowing the same reference gas into both refe- rence and sample cell by activating changeover valve. the measured gas is divided into two, and in one of the flow paths, a high-performance converter is provided to convert carbon monoxide into carbonic acid gas. here, the carbon monoxide in the measured gas is eliminated and the gas is led into one cell of the high-sensitivity infrared analyzer. in the other flow path, the gas is led directly into the other cell of the analyzer. these flow paths are changed over via changeover valves sv1 and sv2 every 50 seconds by means of the changeover valve drive signal transmitted from the analyzer. by carrying out this changeover cyclically, the output of the analyzer varies with the concentration of the carbon monoxide in the measured gas. use of the obtained variation width as a measured value enables improving the s/n ratio and elimi- nating the effects of interfering components plus zero drift. sample gas outlet sample cell sample gas inlet tr i m mer reference cell interference compensating detector distribution cell (interference filter) infrared(single) light source motor rotary sector (one-point chopper) sector sync.signal o 2 meter (option) a/d cpu indicator d/a contact output ram rom rs232c external output hold remote range status range identification o 2 correction value av erage value alarm output 0 to 1v or 4 to 20ma dc operating keys indication gain changeover ac amplifier (option) (option) (option) pump zrf1,2 flow checker filter sample cell sample gas pump zrf4 flow checker filter reference cell sample cell reference gas sample gas sv co/co 2 conver ter pump zrf3 flow checker filter reference cell sample cell co sample gas sv 3 sv 1 sv 2 co/co 2 conver ter fundamental diagram description of differential flow system description of sample switching system optical sampling specification
