Description

Известные способы температурной компенсации радиационных пирометров с термоэлементами снижают чувствительность пирометров и не обеспечивают требующейс  точности измерений.The known methods of temperature compensation of radiation pyrometers with thermoelements reduce the sensitivity of pyrometers and do not provide the required accuracy of measurements.

По предлагаемому способу улучшение компенсации пирометров достигаетс  тем, что термосопротивление частично облучают световым потоком, падающим на термоэлемент.According to the proposed method, an improvement in the compensation of the pyrometers is achieved by the fact that the thermal resistance is partially irradiated with a luminous flux incident on the thermoelement.

Принципиальна  схема температурной компенсации радиационных пирометров согласно предложенному способу изображена на чертеже, где: 1-термоэлемент радиационного пирометра, 2 - термосопротивление , 3, 4, 5 - плечи компенсационного моста, 6 - источник тока питани  моста, 7-регистр ИР уюЩИЙ прибор.A schematic diagram of the temperature compensation of radiation pyrometers according to the proposed method is shown in the drawing, where: 1 is the thermocouple of the radiation pyrometer, 2 is thermal resistance, 3, 4, 5 are the shoulders of the compensation bridge, 6 is the power source of the bridge, 7 is the IR register.

Компенсаци  осуществл етс  с помощью термосопротивлени  2, ВКлюченного в питаемый отдельным источником тока 6 компенсационный мост 5, 4, 5, «спр жение разбаланса которого введено в цепь термоэлемента 1. Термосопротивление 2 измен ет свою величину от изменени  температуры холодных спаев термоэлемента /, а также от частичного облучени  световым потоком, падающим на термоэлемент.Compensation is carried out with the help of thermal resistance 2, switched on a compensation bridge 5, 4, 5 fed by a separate current source, 5, the unbalance conjugation of which is introduced into the thermoelement circuit 1. from partial irradiation with the luminous flux incident on the thermocouple.

Способ позвол ет с большей точностью компенсировать изменение термо-э.д.с. от изменени  температуры холодных спаев и обеспечить одинаковую по величине компенсацию во всем диапазоне измер емых температур, так как с ростом температуры излучени  изменение термоэ .д.с. от изменени  температуры хол,одных спаев также значительно возрастает .The method makes it possible to more accurately compensate the change in thermo-emf. from a change in the temperature of cold junctions and provide equal compensation in the whole range of measured temperatures, since with an increase in the radiation temperature the change in thermoelectric power. from changes in temperature of cold, single junctions also increases significantly.
