Description
Предлагаемый газоанализатор относитс к электрическим газоанализаторам , работающим на принципе теплопроводности газов и радиации нагретых тел.The proposed gas analyzer relates to electric gas analyzers operating on the principle of thermal conductivity of gases and radiation of heated bodies.
Обычно газоанализаторы такого типа выполн ютс в виде камеры, через которую пропускаетс анализируемый газ. В камере помещена спираль, нагреваема электрическим током; при изменении теплопроводности газа, проход щего через эту камеру, измен етс теплоотдача спирали . Измерение теплоотдачи производитс при помощи батареи термопар , э. д. с. которой измер етс вольтметром .Typically, gas analyzers of this type are made in the form of a chamber through which the test gas passes. A spiral placed in the chamber is heated by electric current; as the thermal conductivity of the gas passing through this chamber changes, the heat transfer from the helix changes. The measurement of heat transfer is performed using a thermocouple battery, e. d. which is measured by a voltmeter.
Измерение э. д. с. предлагаетс производить по компенсационной схеме. Дл компенсации э. д. с. батареи терлюпар предлагаетс в цепь накала спирали включать сопротивление , с которого снимаетс компенсирующее напр жение.Measurement e. d. It is proposed to produce under the compensation scheme. For compensation e. d. The battery of the terlupar is proposed to include resistance in the filament circuit of the helix, from which the compensating voltage is removed.

В проточной камере 4 помещена спираль 77, нагреваема током от батареи 8. У спирали помещаетс гор чий спай термопар 5, образующих термобатарею, включенную на приборы через нагрузочное сопротивление 9 и регулировочное сопротивление 70.A spiral 77 is placed in the flow chamber 4, heated by a current from the battery 8. A spiral junction of thermocouples 5 is placed on the spiral, forming a thermocouple connected to the devices through the load resistance 9 and the control resistance 70.
Холодный спай 7 термопар помещен внутри камеры 4 и омываетс анализируемым газом, который протекает по направлению стрелки С. К концу термобатареи и точке соединени сопротивлений 10 и 72 подключен гальванометр 6, отградуированный в процентах содержащегос газа.The cold junction 7 of the thermocouple is placed inside the chamber 4 and is washed by the analyzed gas, which flows in the direction of the arrow C. A galvanometer 6 is connected to the end of the thermopile and to the junction of the resistances 10 and 72, which is graduated as a percentage of the gas contained.
Спираль 77 питаетс током от батареи 8, проход щим через баретор 3, который регулируетс реостатом 7 и контролируетс прибором 2.The coil 77 is powered by the current from the battery 8, passing through the barretor 3, which is controlled by the rheostat 7 and controlled by the device 2.
После включени тока, при просасывании воздуха через камеру 4, реостатом 7 регулируетс ток накала нити и прибор 2 устанавливаетс на красную черту. Спираль 7/ накал етс и излучает тепло, нагревающее гор чий спай термобатареи, выполненный в виде тела малой массы с развитой поверхностью. При установившемс тепловом равновесии стрелка гальванометра 6 реостатом W устанавливаетс на 0. При этом на сопротивлении 72, включенном в цепь гальванометра 6, устанавли313After switching on the current, when air is sucked through the chamber 4, the filament current of the filament is regulated by the rheostat 7 and the device 2 is set to the red line. The helix 7 / is glowing and radiates heat, which heats the hot junction of the thermopile, made in the form of a body of small mass with a developed surface. At steady-state thermal equilibrium, the needle of the galvanometer 6 is set to 0 using a rheostat W. At the same time, a resistance of 72, connected to the circuit of the galvanometer 6, is set313
