Humidity measurement in harsh industrial environments
暂无分享,去创建一个
Based on the relative humidity definition and its measurement principles, this paper presents an improved psychrometer measurement method. The improved measurement method for relative humidity works consistently very well in harsh industrial environments. The sensor construction, measured signal conversion, and system implementation are presented. The Sprung formula is used to calculate the partial vapor pressure of water from wet-bulb temperature. Finally a real world application example is provided to demonstrate the effectiveness of the proposed approach.
