Description
(54) УСТРОЙСТВО ДЛЯ АНАЛИЗА ГАЗОВЫХ СМЕСЕЙ(54) DEVICE FOR ANALYSIS OF GAS MIXTURES
II
Изобрегение отнсх:итс к области аналитического приборосгроени и может бы применено, в частности, дл контрол тенологических газов и жидкостей, преимущественно в химической и нефтехимической , а также в других отрасл х промышленности .The image is relative to its field of analytical instrumentation and could be applied, in particular, to control tenological gases and liquids, mainly in the chemical and petrochemical industry, as well as in other sectors of the industry.
Известны газоанализаторы, использук шие зависимость теплопроводности газовой смеси от состава l. Их недостатком вл етс отсутствие компенсации погрешиостей, обусловленных изменением концентрации неизмер емых компонентов в анализируемой газовой смеси.Gas analyzers are known that use the dependence of the thermal conductivity of a gas mixture on the composition l. Their disadvantage is the lack of compensation for imperfections caused by a change in the concentration of unmeasurable components in the analyzed gas mixture.
Известен газоанализатор, содержащий измерительный мост с рабочими и сра&нительными чувствительными элементами , дсжолнительный мост со сравнительным элементом и посто нными резисторами , устройство с автоматически регулируемым №1ходным напр жением и стабилизированный источник питани 2.A gas analyzer is known, which contains a measuring bridge with working and average sensitive elements, an additional bridge with a comparative element and constant resistors, a device with automatically controlled voltage running voltage and a stabilized power source 2.
Однако этот газоанализатор не позвол ет добитьс то,чности измерени дл However, this gas analyzer does not allow to achieve measurement accuracy for
случа , кс гда увеличение теплсдаровоанооти анализируемой газовой смеси при лзменении кониентраини неизмер емых компонентов приводит к увеличению выходного сигнала измерительного моста.In the event that an increase in the heating temperature of the analyzed gas mixture when the contientry of the immeasurable components is changed, the output signal of the measuring bridge increases.
Целью изобр етениа вл етс повышение точности измерени путем уменьшени вли ни изменени теплопровотаости анализируемой газовой смесн при изменении концентр ацив неизмер емых компонентов .The aim of the invention is to improve the measurement accuracy by reducing the effect of changes in the heat conduction of the analyzed gas mixture when the concentration of the non-measurable components changes.
Это достигаетс тем, что измерительный мост включен последовательно по питанию от стабилиэироваииого источника с дополнительным мостом, измерительна диагональ которого подключена к регулирующему- входу устройства с автоматически регулируемым выходным напр жением , а шлход последнего подключен к диагонали питани дополнительного моста .This is achieved by the fact that the measuring bridge is connected in series with power from a stabilized source with an additional bridge, the measuring diagonal of which is connected to the regulating input of the device with an automatically controlled output voltage, and the schlokhod of the latter is connected to the diagonal power supply of the additional bridge.
