钠中氧含量对于衡量钠腐蚀冲击起着重要的作用,因此准确测量和控制钠中氧含量极为重要。中国原子能科学研究院自2014年起开始研发钠中氧在线分析仪表(又称氧计),该仪表既能实现钠中氧的快速测量,又能避免离线取样分析过程中引入的误差。钠中氧在线分析仪表采用电化学原理,根据氧分压不同建立电势差,从而实现测量。目前研发的电化学氧计其结构由传感器、测量池、温控加热装置、信号处理系统等组成,其中传感器由一端封闭的陶瓷管组成,陶瓷管为氧化
The oxygen content in sodium plays an important role in measuring the impact of sodium corrosion, so it is extremely important to accurately measure and control the oxygen content in the sodium. China Institute of Atomic Energy has been developing a sodium-oxygen on-line analytical instrument (aka oxygen meter) since 2014, which can not only achieve rapid measurement of oxygen in sodium, but also avoid errors introduced during offline sampling and analysis. Sodium oxygen online analytical instruments using electrochemical principles, according to different partial pressure of oxygen to establish potential difference, in order to achieve measurement. At present, the structure of electrochemical oxygen meter developed by the sensor, measuring cell, temperature control heating device, signal processing system, etc., which consists of one end of the ceramic tube closed, the ceramic tube is oxidized
