Abstract
Condensation may occur in a vacuum gauge which is used for measuring the pressure in a vacuum system in which a liquid is being evaporated at elevated temperature and the pressure of the liberated vapour exceeds the saturation pressure of this vapour at the temperature of the vacuum gauge, which is usually at ambient temperature. In this paper, a pressure-measuring method is described which prevents condensation or liquefaction occurring in the manometer or in the line connecting it to a vacuum system. The essence of this method is the reduction of the vapour pressure in the vacuum gauge, or in the pipeline leading to it, by a small stream of air, to a value at which condensation or liquefaction cannot occur. A short note is also added on the use of mercury manometers on `wet' vacuum systems.
