Description

Известные газоанализаторы на кислород не обладают достаточ«ой чуБСТвительностью.Known gas analyzers for oxygen are not sufficiently sensitive.

Предлагаемый магнитный газоанализатор отличаетс  от известных тем, что в нем о концентрации парамагнитного газа (кислорода) суд т по углу отклонени  этого газа при его движении под воздействием двух сил: тепловой и термомагнитной конвекции.The proposed magnetic gas analyzer differs from the known ones in that the concentration of the paramagnetic gas (oxygen) is judged by the angle of deflection of this gas during its movement under the influence of two forces: thermal and thermomagnetic convection.

В рабочей камере устройства помещены точечный источнИк тепла и теплочувствительные элементы, в цепь которых включен нуль-индикатор , устанавливаемый в нулевое положение изменением одного из трех параметров: угла поворота системы теплочувствительных элементов, температуры источника тепла или напр женности магнитного дол . Любой из этих парамеФров может быть проградуирован в процентном содержании газа.The working chamber of the device contains a point source of heat and heat sensitive elements, the circuit of which includes a null indicator, set to zero position by changing one of three parameters: the angle of rotation of the system of heat sensitive elements, the temperature of the heat source or the intensity of the magnetic dol. Any of these parameters can be graduated in percentage of gas.

Схема устройства дана на чертеже.Diagram of the device is given in the drawing.

В рабочей камере 1 размещены электрический нагревательный элемент 2 и теплочувствительные элементы 3, включенные в схему мостика с измерителем 4, дроградуированным в % содержании кислорода (О2). Поле магнита 5 направлено под углом к вертикали. Нагретые частицы газа, двига сь в камере под действием естественной тепловой и тепломагнитной конвекции, из eн ют температуру теплочувствительных элементов , вызыва  тед самым разбаланс моста.In the working chamber 1 there is an electric heating element 2 and heat-sensitive elements 3, included in the bridge circuit with a meter 4, which is graded in% oxygen content (O2). The field of magnet 5 is directed at an angle to the vertical. The heated gas particles, moving in the chamber under the action of natural thermal and thermal-magnetic convection, from the temperature of the heat-sensitive elements, cause the bridge to become unbalanced.

Предмет изобретени Subject invention

Устройство дл  определени  количества пара.агнитпого газа (кислорода ) в газовоздущной смеси с помощью магнитного газоанализатора , снабженного рабочей камерой, пронизанной неравномерным магнитным полем, отличающеес  тем, что, с целью повыщени  чувствительности устройства, внутри камеры размещены точечный или линейный источник тепла и система теплочувствите.пьных элементов, в цепь которых включен нуль-индикатор, устанавливаемый в нулевое положение изменением одного из трех параметров: угла поворота системы теплочувствительных элементов, температуры источника тепла или нацр женности магнитного лол , по величине которых суд т о процентном содержании исследуемого газа.A device for determining the amount of vapor-magnetic gas (oxygen) in a gas-air mixture using a magnetic gas analyzer equipped with a working chamber pierced by an uneven magnetic field, characterized in that, in order to increase the sensitivity of the device, a point or linear heat source is placed inside the chamber elements, in the chain of which a zero-indicator is inserted, set to the zero position by changing one of three parameters: the angle of rotation of the system of heat-sensitive elements the temperature of the heat source or the national density of the magnetic lol, the magnitude of which is judged on the percentage content of the test gas.
