A Compensation Electrothermograph for Liquids and Gases

摘要

A follow-up system of an electrothermograph intended for conducting physicochemical studies of processes, such as boiling, in liquids and gases is described. A new bridge device, in which a common-mode signal that unbalances the bridge does not appear, is used in the instrument. The advantages of the follow-up systems built according the scheme proposed are shown. The measurement technique and the main metrological characteristics of the instrument are described. An example of actual studies of a superintense nucleate-boiling regime is given.
