等容加热式饱和蒸汽湿度监测仪研制

The research and development of a saturated steam wetness measuring instrument based on an isochoric-heating method

针对饱和蒸汽的湿度难于测量的问题 ,本文提出了一种新型的测试方法并研制了基于微处理机的智能监测装置。与现有监测方法相比 ,本方法原理可靠、干扰小、测量精度高。

In view of the fact that it is hard to measure the wetness of satured steam,this paper presents a new measurement method and an intelligent instrument based on a microprocessor.Compared with the existing method,the isochoric heating method has many good features,such as the reliable mathematical model,slight disturbance,high measruement accuracy,etc.,the wetness measuring instrument is provided with various functions and its probe is simple in construction .
