Method and device for measurement of dew point temperature

Abstract

The invention relates to a method and device for measuring the dew point of humid gases, and more particularly to determining the humidity of gas mixtures according to the dew point, and can be used in all fields in which measurements of this sort are required. The claimed device is capable of determining a dew point in a range of from +45° C. to +95° C., which corresponds to a moisture content of from 65 to 3000 g of water per 1 kg of dry air. The device performs continuous measurement. The essence of the invention is that the claimed method for measuring dew point consists in determining the point of a sudden change in the temperature gradient along a tubular cooler through which the humid gas under examination is passed, and calculating the temperature at which this change takes place. The tubular cooler is cooled by the surrounding air. The device has a generator for generating an output signal that transmits information about the parameters of the gas to external systems and that can be used as an input signal for a moisture content regulator. The device can be equipped with a digital indicator for displaying the gas parameters obtained.
