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. Known optical pyrometers employed for measuring high temperatures, constructed lo measurement principle energy radiation-sensitive detectors, in conjunction with which the stability and the accuracy of their readings is a direct function of the receiver iz.tucheny properties of the photosensitive member.

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 . The reference emitters in such devices uses a conventional incandescent lamp, which, as shown by the study itself alters its properties and requires further stabilized source for their power.

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. Taki.m obrazo.m, using as a reference emitter incandescent lamp is a substantial disadvantage of the known optical pyrometers, as complicates their design and does not provide the desired stability.

Предложенный фотоэлектрический компенсационный ркостный пиро.метр устран ет указанные недостатки. Proposed photoelectric compensation luminance piro.metr obviates these drawbacks.

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

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

На полупроводниковый чувствительный элемент / фотоэлектрического пиро.метра с помощью вибрирующей заслонки 2 попеременно поступает сигнал от объекта .У измерени и эталонного радиоактивного излучател 4. The semiconductor sensor / photoelectric piro.metra via vibrating valve 2 alternately receives a signal from the object .u measuring and reference radiation 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. As such a radiator device employed in a radioactive radiation source, e.g. isotope C (°, gamma radiation which has an energy of 1.33 Lao, and its half-life is 5.3 g

Изменение интенсивности радиоактивного излучени производитс комненсационным клином 5. a radiation intensity variation produced komnensatsionnym 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 .pomoschyu compensating wedge 5 and 6, the electronic unit 7 equalize servo reference radioactive radiation emitter 4 from the object 3 -measurement radiation.

Отсчет осуществл етс по шкале 8. Counting is performed on a scale 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 instrument eliminated the effect of parameters of the circuit elements, since the difference signal acts on the actuator that moves the compensating wedge so that the difference signal is limited to the value zero.

Предмет изобретени Subject of the invention

Фотоэлектрический компенсационный ркостный пирометр, отличающийс тем, что в качестве эталонного источника в нем применен радиоактивный источник излучени , например . Photoelectric the compensation luminance pyrometer, characterized in that the reference source is applied to it a radioactive radiation source, for example.
