Description
Иэобрете ше относитс к способам анализа газов и может быть использовано дл высокоточных измерений относительной влажности Газов, а также при создании эталонов и образцовых средств йомерений. Известен диэлькометрический способ измерени относительной влажности газов , основанный на зависимости диэлектрической проницаемости газов от вла5&ности l. Этот способ не вл етс абсолютным н .дл его реализации требуетс градуировка средств измерени . Наиболее близок к предложенному способ измерени относительной влажности газов, основанный на измерении диэлектрической проницаемости ( ), сухого газа (с нулевой концентрацией влаги), а затем 6 того же, но влажного газа, подлежащего исследованию 2. Прибор, реализукшшй этот способ, градуируетс по газам с известной влажностью f , что и огршшчивает точность измерени Ч . ти газ что чес до пар ред где сит Цель изобретени - повышение точносизмерени относительной влажности ов. Поставленна цель достигаетс тем, дополнительно измер ют диэлектрикую проницаемость газа, доведенного стопроцентного насьццени вод ными ами, и относительную влажность f опел ют по формуле; 100% к f - диэлектрическа проницаемость сухого газа; f - Д1{электрическа проницаемость газа с определ емым содержанием влажности; диэлектрическа проницаемость газа, доведенного до стопроцентного насьццени вод ными парами , i Предлагаемый спсюоб измерени отноельной влажности в статическом режиThe invention relates to gas analysis methods and can be used for high-precision measurements of the relative humidity of gases, as well as for creating standards and exemplary means of measurement. A dielectric method is known for measuring the relative humidity of gases, based on the dependence of the dielectric constant of gases on the moisture content of l. This method is not absolute. To implement it, calibration of the measuring means is required. Closest to the proposed method of measuring the relative humidity of gases, based on measuring the dielectric constant (), dry gas (with zero moisture concentration), and then 6 of the same, but moist gas to be studied 2. The device, realizing this method, is graduated by gas with a known humidity f, which limits the accuracy of the measurement. This gas is up to par ed where the sieve. The purpose of the invention is to increase the accuracy of measuring the relative humidity of s. This goal is achieved by additionally measuring the dielectric permeability of a gas brought 100% by water and the relative humidity f is blanketed by the formula; 100% f - dielectric constant of dry gas; f - D1 {electrical permeability of gas with a detectable moisture content; the dielectric constant of a gas brought to 100% absolute by water vapor, i Offered a measure of relative humidity measurement in static mode
