3—7、结构参数对气体分析器特性的影响气体分析器刻度曲线形状和灵敏度完全取决于敏感元件、分析室及磁力系统磁极的结构。由以上概念(§3—3、3—4和3—5)可作出如下结论: 1.具外部对流且彼此绝热的敏感元件,若元件位于极靴之上时(磁场梯度向上)可在含氧量很大范围内得到线性特性曲线。 2.为了测量低含氧量(0～10％),最好采用具有热联系的敏感元件,该敏感元件的
3-7. Effects of Structural Parameters on Gas Analyzer Characteristics Gas analyzer scale curve shape and sensitivity depend entirely on the structure of the sensing element, the analysis chamber, and the poles of the magnetic system. From the above concepts (§3-3, 3-4 and 3-5) the following conclusions can be drawn: 1. Sensitive elements with external convection and mutual thermal insulation, if the element is located above the pole piece (magnetic field gradient upwards) A large range of oxygen to obtain a linear characteristic curve. 2. To measure low oxygen levels (0-10%), it is best to use a heat-sensitive sensor that has
