Formulae for Determination of Dew-point Temperature of Compressed Air for Automatic instruments

Hong Xiao

Abstract

Based on the theory of engineering thermodynamics,the influence of pressure on dew point Temperature of compressed air is analyzed and a set of formulae,accurate and simple,are provided for the determination of the pressure dew-point temperature of air supply for automatic instruments when the steam content in the air supply is measured under normal pressure.The application range of the formulae is from-60 to 70℃ for dew-point temperatures.
