Description
(5) ПНЕВМАТИЧЕСКИЙ ПРЕОБРАЗОВАТЕЛЬ ГИГРОМЕТРА(5) PNEUMATIC CONVERTER OF HYGROMETER
1.one.
Изобретение относитс , к аналитйческому приборостроение и может быть использовано в лробоотборных пневматических устройствах гигрометров дл измерени влажности агрессивных газовых сред.The invention relates to analytical instrumentation and can be used in sampling pneumatic hygrometers to measure the humidity of aggressive gaseous media.
Известен гигрометр, предназначен ный дл измерени влажности хлорсодержащих газов, содержащий кулонометрический чувствительный элемент, магистрали подвода и отвода анализируемого газа и регул тор расхода газа 1. ,A known hygrometer, designed to measure the humidity of chlorine-containing gases, contains a coulometric sensitive element, the supply and removal lines of the analyzed gas and the gas flow regulator 1.,
Регул тор расхода газа в известном датчике гигрометра, предназначенный дл поддержани на посто нном значении расхода анализируемого газа через чувствительный элемент , состоит из регул тора давлени газа типа до себ и установленного перед ним по ходу газа пнеамосопрот 1влени и выполнен из материалов , корродирующих в среде анализируемого газа. Выполнение регул тора расхода газа из материалов, коррозиомно устойчивых в среде анализируемого газа, вследствие сложности его конструктивного исполнени , например из стекла и фторопластов, нецелесообразно .The gas flow controller in the well-known hygrometer sensor, designed to keep the analyte gas flow rate through the sensing element at a constant value, consists of a self-pressure gas regulator and a front-mounted gas flow meter in front of it and is made of materials that are corrosive in the medium being analyzed gas. It is impractical to make a gas flow regulator from materials that are corrosion resistant in the environment of the analyzed gas, due to the complexity of its design, for example, made of glass and fluoroplastic.
По этой причине известный гигрометр имеет очень низкие показатели надежности и малый срок службы. Крог ме.того, регул тор давлени газа в For this reason, the well-known hygrometer has very low reliability and low service life. Krog me, the gas pressure regulator in
10 известном гигрометре очень чувствителен к колебани м давлени газа в магистрали его отвода в дренажную линию, что приводит к нестабильнос j ти в показани х гигрометра и, следовательно , к снижению точности измерений влажности газа.10 of the known hygrometer is very sensitive to fluctuations in the pressure of gas in the line of its outlet to the drain line, which leads to instability in the readings of the hygrometer and, consequently, to a decrease in the accuracy of gas humidity measurements.
