| 摘 要： | CO2监测分析仪在监测过程中,CO2监测值的精度是由CO2监测分析仪的桥室参比温度是否恒定而决定的.老式监测分析仪桥室温度是采用断续的双位恒温调节,其温度调节误差大,一般只能在±1℃左右,所以CO2监测值的精度低.采用微机交流调压的CO2监测分析仪桥室恒温调节,其温度调节器采用PID调节,使桥室温度误差可控制在±0.2℃,提高了CO2监测值的监测精度.

| Abstract: | The monitoring accuracy of intelligent carbon dioxide monitoring device depends on the effect of isothermal parameter of the conducting cell. During monitoring if the temperature of the conducting cell could not maintain unchanged, the fluctuation of temperature results in the unstability of the isothermal parameter. It directly influences the accuracy of monitoring carbon dioxide. The adoption of the duty ratio of alternation voltage under the command of computer would satisfy the demand of the isothermal control and increases the monitoring accuracy of the carbon dioxide monitor. |
