Изобретение относитс к ко;1тактной термометрии.The invention relates to; 1 tact thermometry.
Известна термопара с р дом спаев дл измерени распределени температуры в потоке газа, содержаща общий термоэлектрод с припаенными к нему противополо.л ;с1знака пол рности электрода ;и . Извес г на термопара содержит спай, не позвол ю щий использовать его при высоких Tef/jepr,турах .A well-known thermocouple with a series of junctions for measuring the temperature distribution in a gas flow, containing a common thermoelectrode with an opposite polarity attached to it, a sign of the polarity of the electrode, and. The weight of the thermocouple contains a junction that does not allow it to be used at high Tef / jepr tours.
Известна термопара, содержаща общий термоэлектрод с приваренными к нему в нескольких местах противоположного знака электродами, что позвол ет расширить диапазон и.змер емь Х температур ll.A known thermocouple containing a common thermoelectrode with electrodes welded to it in several places of opposite sign, which makes it possible to expand the range and dimension X of temperatures ll.
Однако известна термопара неудобна тем, что в ней возникает дополнительна погрешность измерени за счет увеличени химической неоднородности общего термо- электрода в местах его сварки с электро- дами противоположной пол рности.However, a thermocouple is known to be inconvenient because an additional measurement error occurs in it due to an increase in the chemical inhomogeneity of the common thermoelectric electrode in the places of its welding with electrodes of opposite polarity.
Цель изобретени - повышение точнос-ти измерени температуры.The purpose of the invention is to improve the accuracy of temperature measurement.
Дл этого в рассечку между общим тер- моэлектродом и противоположного знака по- For this, a cut between the common thermal electrode and the opposite sign
.1 рности термоэлектродами введен дополнительный термоэлектрод, подсоединенный одним концом к общему термоэлектроду, а другим - к термоэлектродам противоположного знака пол рности, причем дополнительный термоэлектрод выполнен из того же материала , что и общий..1 thermoelectrodes introduced an additional thermoelectrode connected at one end to a common thermoelectrode, and the other to thermoelectrodes of opposite polarity, with the additional thermoelectrode made of the same material as the common one.
На чертеже изображена предлагаема термопара.The drawing shows the proposed thermocouple.
Термопара содержит объект измерени 1, общий термоэлектрод 2, дополнительный термоэлектрод 3, термоэлектроды 4 с противоположным знаком пол рности по отношению к общему, измерительные спаи 5 термоэлектродов.The thermocouple contains the object to be measured 1, the common thermoelectrode 2, the additional thermoelectrode 3, the thermoelectrodes 4 with the opposite polarity with respect to the common one, the measuring junctions of 5 thermoelectrodes.
Дополнительные термоэлектроды 3 исключают возможность возникновени химической неоднородности общего термоэлектрода при сварке измерительных спаев 5,Additional thermoelectrodes 3 exclude the possibility of the occurrence of chemical heterogeneity of a common thermoelectrode during welding of measuring junctions 5,
