新型多孔介质局部含湿量测试仪的研究

A New Model of Instrument for Measuring the Local Moisture Content in Wet Porous Media

采用针型电容测湿传感器和单片微处理机技术研制成一种新型多孔介质局部含湿量测试仪。本文论述该测试仪的组成、工作原理和硬、软件结构及其特点。实验结果表明，可望满足多孔介质局部含湿量测量的实用要求。

A new model of instrument for measuring the local moisture content in wet porous media is developed by use of the needle-type capacitance sensor and single-chip microcomputer techniques. The working principle, the structure and characteristic of the hardware and software of the instrument are discussed. The experimental results show that the instrument could meet the needs for measuring the local moisture content in wet porous media.
