Description
(54) ТЕРМОПАРА(54) THERMOPAR
щающей попадание наносимого вещества. Затем на поверхность стержн .надевают защитную трубку, а другой .половине жгута придают форму цилиндра, расположенного коаксиально со стержнем, ,и пропитывают его пироуглеродом. После этого удал ют защитную трубку с внутреннего электрода. Внутренний электрод термопары вл етс положительным, внещний - отр-ицательным .application of the applied substance. Then a protective tube is put on the surface of the rod, and the other half of the rope is shaped into a cylinder located coaxially with the rod, and it is impregnated with pyrocarbon. Thereafter, the protective tube is removed from the inner electrode. The internal electrode of the thermocouple is positive, the external electrode is positive.
При помещении гор чего «сна термопары 4 в измер емый объект, преимущественно в газовый лоток с температурой до 2000° С (электроды термопары генерируют термоэдс), регистрирующей прибор фиксирует показание, пропорциональное измер емой тем-пературе.When a thermocouple 4 is placed hot in the measured object, mainly in a gas tray with a temperature of up to 2000 ° C (thermocouple electrodes generate a thermopower), the instrument records a reading that is proportional to the measured temperature.
Испытани опытных образцов описываемой термопары показали, что при эксплуатации в газовых потоках .при скорости потока до150 м1сек и температуре до 2000° С ресурс составл ет около 25 мин., в то врем 1как .известна термопара практически выходит из стро сразу. Одновременно увеличиваетс точность измерений, так ка.к логрещность воспроизводимости пока.занийTests of prototypes of the described thermocouple showed that when operating in gas streams, at a flow rate of up to 150 m1 sec and a temperature of up to 2000 ° C, the resource is about 25 minutes, while at the same time the known thermocouple almost went out of order. At the same time, the accuracy of measurements is increased, so that the reproducibility of reproducibility is for now.
описываемой термопары составл ет примерно 0,8%, а известной термопары - около 5%.the thermocouple described is about 0.8%, and the known thermocouple is about 5%.
