Description

Известные оптические пирометры, примен емые дл  измерени  высоких температур, построены ло принципу измерени  энергии излучени  чувствительными приемниками, в св зи с чем стабильность и точность их показаний находитс  в пр мой зависимости от свойств приемника из.тучений фоточувствительного элемента.The known optical pyrometers used for measuring high temperatures were built on the principle of measuring the radiation energy by sensitive receivers, and therefore the stability and accuracy of their readings is directly dependent on the properties of the receiver due to the length of the photosensitive element.

В качестве эталонного излучател  в таких приборах используетс  обычна  лампа накаливани , котора , как показали исследовани , сама измен ет свои свойства и требует дополнительного стабилизированного источника дл  своего питани .A standard incandescent lamp is used as a reference emitter in such devices, which, as studies have shown, itself changes its properties and requires an additional stabilized source for its power supply.

Таки.м образо.м, применение в качестве эталонного излучател  лампы накаливани   вл етс  существенным недостатком известных оптических пирометров, так как усложн ет их конструкцию и не обеспечивает требуемой стабильности.Thus, the use as a reference emitter of an incandescent lamp is a significant disadvantage of the known optical pyrometers, since it complicates their design and does not provide the required stability.

Предложенный фотоэлектрический компенсационный  ркостный пиро.метр устран ет указанные недостатки.The proposed photoelectric compensation capacitance pyrometer eliminates these disadvantages.

Достигаетс  это тем, что в описываемом приборе в качестве эталонного источника при.менен радиоактивный источник излучени , например .This is achieved by the fact that in the described device a radioactive radiation source, for example, is used as a reference source.

На чертеже изображена принципиальна  схема описываемого прибора .The drawing shows a schematic diagram of the described device.

На полупроводниковый чувствительный элемент / фотоэлектрического пиро.метра с помощью вибрирующей заслонки 2 попеременно поступает сигнал от объекта .У измерени  и эталонного радиоактивного излучател  4.A semiconductor sensing element / photoelectric pyrometer with a vibrating valve 2 alternately receives a signal from the object. The measurement and the reference radioactive emitter 4.

В качестве такого излучател  в приборе применен радиоактивный источник излучени , например изотоп С(°, гамма излучени  которого обладает энергией 1,33 лэо, а период его полураспада составл ет 5,3 г.A radioactive source of radiation, for example, an isotope C (° C, whose gamma has an energy of 1.33 leo, and its half-life is 5.3 g, is used as such a radiator.

Изменение интенсивности радиоактивного излучени  производитс  комненсационным клином 5.The change in the intensity of radioactive radiation is produced by the compensation wedge 5.

С .помощью компенсационного клина 5 электронный блок 6 и сервопривод 7 уравнивают излучение эталонного радиоактивного излучател  4 с излучением объекта 3 -измерени .With the help of the compensation wedge 5, the electronic unit 6 and the servo drive 7 equalize the radiation of the reference radioactive emitter 4 with the radiation of the object 3 -measurement.

Отсчет осуществл етс  по шкале 8.Counting is done on a scale of 8.

В приборе исключено вли ние параметров элементов схемы, так как разностный сигнал воздействует на сервопривод, перемещающий компенсационный клин, таким образом, что величина разностного сигнала сводитс  к нулю.The device eliminates the influence of the parameters of the circuit elements, since the differential signal acts on the servo driving the compensation wedge, so that the value of the differential signal is reduced to zero.

Предмет изобретени Subject invention

Фотоэлектрический компенсационный  ркостный пирометр, отличающийс  тем, что в качестве эталонного источника в нем применен радиоактивный источник излучени , например .A photoelectric compensation pyrometer, characterized in that it uses a radioactive radiation source, for example, as a reference source.
