汽油辛烷值分析仪的研制

所研制的汽油辛烷值分析仪采用空气与汽油混合物在高温下的氧化反应的冷馅反应原理。测是量结果符合GB503-85和GB5487-85的规定。测量范围为5个辛烷值单位：研究法(RON)：85～90或90～95或95～99；马达法(MON)：68～73或73～78或78～83。**度、重复性、再现性、稳定性、分辨率：不大于±0.3辛烷值。分析周期：5～100min，可程序设定。耗油量：每次进样约0.125*#ml。温度反应器装置根据国家标准GB38362083规定要求设计成隔爆型，防爆标志为ExdⅡAT4，符合GB3836.1-83规定。能在线连续测量辛烷值。简要地介绍了防爆型汽油辛烷值分析仪的测量原理、测量电路和仪表结构。
