A New Style High Precision Sulfur Dioxide Measurement Mechanics of Zero Variation
In order to enhance measurement precision of sulfur dioxide, the improved sensor mechanics are studied. According to Lambert-Beer Law, the mathematic model of sulfur dioxide measurement is deduced, which is about strength ratio of reference beam and measuring beam. Reversible look-up table is deduced to solve the nonlinearity variation problem in this mathematic model, and it achieves linearity of the sensor. Furthermore, a new zero variation and high precision software frame is put forward to about sulfur dioxide sensor. In addition, double optical paths gas room is brought forward to survey sulfur dioxide. Finally, data in the experiment are analyzed, it is proved that this method put forward to enhance measurement precision is easy to implement in this paper. And it has high precision, strong anti-jamming capability, as well as real-time and on-line measurement sulfur dioxide required at industry scenes, so this method has preferable vendibility and application foreground et..
