Abstract
La présente invention concerne un procédé et un dispositif pour déterminer la température du point de condensation d'un corps. Le procédé et le dispositif se caractérisent par le fait qu'un miroir est soumis à un cycle de température de refroidissement et de chauffage, le refroidissement du miroir s'effectuant sur deux plages, une rapide suivie d'une lente, la température de changement entre les deux plages étant déterminée en fonction de la température du point de condensation des corps mesurée sur un cycle précédent. L'invention trouve une application particulièrement avantageuse dans la mesure du point de rosée des hydrocarbures.The present invention relates to a method and a device for determining the temperature of the dew point of a body. The method and the device are characterized in that a mirror is subjected to a temperature cycle of cooling and heating, the cooling of the mirror taking place in two ranges, a fast followed by a slow, the temperature of change. between the two ranges being determined according to the temperature of the condensation point of the bodies measured over a previous cycle. The invention finds a particularly advantageous application in the measurement of the dew point of hydrocarbons.
