Изобретение относитс к измерительной технике, а именно к газоаналитическим приборам, предназначенным дл измерени концентрации аммиака в газовоздушных смес х, и может примен тьс при азотировании и нитроцементации стальных изделий.The invention relates to a measurement technique, namely, gas analysis devices for measuring the concentration of ammonia in gas-air mixtures, and can be used in nitriding and carbonitriding steel products.
Известен прибор дл измерени концентрации аммиака, содержащий два капилл ра, поглотитель аммиака, дифференциальный манометр с вторичным прибором, присоединенный к одному из капилл ров и стабилизатор давлени 1A known instrument for measuring the concentration of ammonia, containing two capillaries, an ammonia absorber, a differential pressure gauge with a secondary instrument, connected to one of the capillaries, and a pressure stabilizer 1
Недостатком известного прибора вл етс низка точность, вследствие вли ни температуры и давлени анализируемого газа, а также невозможность измерени концентрации аммиака в газе, разбавленном, например, азотом .A disadvantage of the known instrument is low accuracy, due to the influence of temperature and pressure of the gas being analyzed, as well as the impossibility of measuring the concentration of ammonia in a gas diluted with, for example, nitrogen.
Наи;более близким по технической сущности к изобретению вл етс устройство дл измерени концентрацииThe closest to the technical essence of the invention is a device for measuring the concentration
амййака, содержащее газовый мост, образованный четырьм капилл рами, поглотитель аммиака и вторичный прибор 2.an amyyaka containing a gas bridge formed by four capillaries, an ammonia absorber and a secondary device 2.
Недостатком этого устройства вл етс низка точность, обусловленна нелинейностью газового моста, вследствие выполнени его неуравновешенным , малой чувствительностью диф10 ференциального манометра, зависимостью показаний от давлени анализируемого газа, а также изменение параметров (плотности, в зкости) газа, вследствие увлажнени его в погло15 тителе.The disadvantage of this device is low accuracy due to the non-linearity of the gas bridge, due to its unbalanced, low sensitivity of the differential pressure gauge, dependence of the readings on the pressure of the analyzed gas, as well as changes in the parameters (density, viscosity) of the gas, due to its moisture in the absorber of the gas.
Цель изобретени - повышение точности измерени при малых концентраци х аммиака за счет ликвидации погрешностей , обусловленных увлажне- . The purpose of the invention is to improve the measurement accuracy at low concentrations of ammonia by eliminating errors due to humidification.
20 нием газа в поглотителе.20 by the use of gas in the absorber.
