Hlalosa ka ho qaqileng maemo a tekanyo ea mocheso oa thermocouple

- 2021-09-29-

Thermocoupleke mofuta oa karolo ea kutlo ea mocheso, ke mofuta oa sesebelisoa, thermocouple ka kotloloho e lekanya mocheso. Lupu e koetsoeng e entsoe ka batsamaisi ba babeli ba nang le lisebelisoa tse fapaneng tsa popeho. Ka lebaka la lisebelisoa tse fapaneng, bongata bo fapaneng ba lielektrone bo hlahisa phasalatso ea elektronike, 'me monyetla o hlahisoa kamora botsitso bo tsitsitseng. Ha ho na le mocheso oa gradient lipheletsong ka bobeli, hona joale ho tla hlahisoa kahare, 'me ho tla hlahisoa matla a motlakase. Phapang e kholo ea mocheso, ea hona joale e kholo. Kamora ho lekanya matla a motlakase, matla a mocheso a ka tsejoa. Ha e le hantle, thermocouple ke sesebelisoa se fetolang matla se fetolang matla a futhumatsang hore e be matla a motlakase.

Melemo ea tekheniki ea thermocouples:thermocouplesna le bophara ba litekanyo tsa mocheso o pharaletseng le ts'ebetso e batlang e tsitsitse; ho nepahala ha litekanyo tse phahameng, thermocouple e kopane ka kotloloho le ntho e lekantsoeng, mme ha e angoe ke mahareng; nako ea ho futhumatsa ka mocheso e potlakile, mme thermocouple e nahanela liphetoho tsa mocheso; Mefuta ea ho lekanya e kholo, thermocouple e ka lekanya mocheso khafetsa ho tloha ho -40 ~ + 1600â „ƒ; thethermocouplena tshebetso e ka tšeptjoang le e ntle phetha molao matla. Long bophelo tšebeletso le tlhomamiso bonolo. Banyalani ba galvanic ba tlameha ho etsoa ka lisebelisoa tse peli tsa conductor (kapa semiconductor) tse nang le thepa e fapaneng empa ba fihlella litlhokahalo tse itseng ho theha lupu. Ho tlameha hore ho be le phapang ea mocheso lipakeng tsa setsi sa ho lekanya le sesebelisoa sa litšupiso sa thermocouple.

Bakhanni kapa li-semiconductors A le B tsa lisebelisoa tse peli tse fapaneng li kopantsoe hammoho ho etsa lupu e koetsoeng. Ha ho na le phapano ea mocheso lipakeng tsa lintlha tse peli tse hoketsoeng 1 le 2 ea batsamaisi A le B, matla a motlakase a hlahisoa lipakeng tsa tse peli, ka hona a theha leqhubu le leholo kahare. Ketsahalo ena e bitsoa phello ea motlakase. Li-thermocouples li sebetsa li sebelisa sena.
