Description

В известных способах определени  температур пламени методом обращени  спектральных линий измер ема  температура «е должна превышать температуру эталонного источника, при этом точность измерени  получаетс  недостаточнойПредлагаемый способ отличаетс  от известных повышенной точностью измерени . Это достигаетс  тем, что экстрапол ци   ркости эталонной лампы производитс  плавно независимым изменением коэффициентов усилени  усилителей фототоков, соответствуюших модулированному суммарному излучению лампы и пламени и отдельно пламени.In the known methods for determining flame temperatures by reversing spectral lines, the measured temperature must not exceed the temperature of the reference source, and the measurement accuracy is insufficient. The proposed method differs from the known ones by increased measurement accuracy. This is achieved by extrapolating the reference lamp with a smoothly independent change in the gains of the photocurrent amplifiers corresponding to the modulated total emission of the lamp and the flame and the flame alone.

Па чертеже дана схема дл  осуш,ествлени  описываемого способа.A drawing is a diagram for drying, describing the described method.

Свет эталонной лампы / модулируетс  вращаюш,имс  диском 2 с отверсти ми , затем с помошью линз и 4 нить лампы и исследуемое плам  5 проектируютс  на входную шель спектрографа 6. Выделенна  спектрографом спектральна  лини  проектируетс  линзой 7 на фотокатод фотоумножител  8. В анодной цепи фотоумножител  по вл ютс  токи, соответствующие модулированному свету эталонной лампы 1 и свету исследуемого пламени 5. Эти токи раздел ютс  либо специальным фильтром-разделителем 9, либо усилител ми 10 и //, настроенными соответственно на частоту модулированного света эталонной лампы и на ток, вызванный светом исследуемого источника. После усилителей токи поступают в осциллограф 12. на экране которого производитс  наблюдение обращени  линии.The reference lamp light is modulated by rotating with a disk 2 with holes, then with the help of lenses and 4 lamp filaments and the flame under study 5 are projected onto the spectrograph 6 inlet beam. are the currents corresponding to the modulated light of the reference lamp 1 and the light of the flame under study 5. These currents are separated either by a special separator filter 9 or by amplifiers 10 and // tuned to the frequency ovannogo reference beam lamp and the current caused by the test light source. After the amplifiers, the currents enter the oscilloscope 12. On the screen of which the line circulation is observed.

Уравнивание выходных сигналов усилителей фототоков производитс  изменением коэффициентов усилени  усилителей.Equalizing the output signals of photocurrent amplifiers is done by changing the gains of the amplifiers.

Таким образом, предлагаемый способ позвол ет достаточно быстро и точно измерить высокие температуры технических пламен с помощью низкотемпературной эталонной лампы по заранее градуированному прибору .Thus, the proposed method allows to quickly and accurately measure the high temperatures of technical flames using a low-temperature reference lamp using a pre-calibrated instrument.
