摘要:
 旨在对国内外目前常用的3种基于顺磁特性的氧气浓度检测系统进行综合介绍,进而展示一种新的基于顺磁法的磁压敏测量装置系统。通过研究氧气具有的强顺磁特性这一特殊的物理性质在3种不同的检测系统中检测到的物理量,比如热磁对流、压力差和密度梯度等来计算混合样气中氧气的含量。接着又对应介绍了热磁对流式、磁机械式、磁压力式3种磁氧分析系统的相关内容,通过对其原理内容、内部构造、工作机理的对比与分析,让读者对这3种分析系统有更清晰的认识,对这3种检测方法理解的更透彻,以便于更好的使用这3种方法进行氧气浓度的检测。最后对本文新提出的测量装置从组成结构、工作原理、波形显示等方面进行简单论述。
Abstract:
 Three commonly used oxygen concentration detection systems based on paramagnetic properties at home and abroad are introduced in this paper and an innovative magnetic pressure measurement system based on paramagnetic method is further proposed. The special physical quantities of oxygen, strong paramagnetic properties, detected by three kinds of detection systems are studied. The detected measurements, such as thermal magnetic convection, pressure difference and density gradient, are used to calculate the oxygen content in mixed gas. The information about the three kinds of analyzers, namely thermomagnetic convection type, magnetic mechanical type and magnetic pressure type, are also introduced. We compare and analyze their principle, internal structures and working mechanisms to made readers understand the three kinds of analyzers more clearly and thoroughly, so that they can choose the appropriate analyzer to detect the oxygen concentration. Finally, the composition, structure, working principle and waveform display of the proposed innovative measurement device are briefly discussed.
