Kamoo Thermocouple Sensors e Sebetsang Kateng
Ha ho na le li-conductors tse peli tse fapaneng le li-semiconductors A le B ho etsa loop, 'me lipheletsong tse peli li hokahane, ha feela mocheso oa mahlakoreng a mabeli a fapane, mocheso oa ntlha e' ngoe ke T, e bitsoang T. pheletso ea ho sebetsa kapa pheletso e chesang, 'me mocheso oa pheletsong e' ngoe ke HO , e bitsoang pheletso ea mahala kapa pheletso e batang, ho na le hona joale ka har'a lupu, ke hore, matla a electromotive a teng ho loop a bitsoa matla a thermoelectromotive.Ketsahalo ena ea ho hlahisa matla a electromotive ka lebaka la ho se tšoane ha mocheso o bitsoa phello ea Seebeck.Ho na le liphello tse peli tse amanang le Seebeck: pele, ha hona joale ho phalla ka har'a matekoane a li-conductor tse peli tse fapaneng, mocheso o kenngoa kapa o lokolloa mona (ho itšetlehile ka tataiso ea hona joale), e bitsoang phello ea Peltier;Ea bobeli, ha motlakase o phalla ka har'a conductor e nang le mocheso oa mocheso, conductor e monya kapa e ntša mocheso (ho itšetlehile ka tataiso ea hona joale e amanang le mocheso oa mocheso), e tsejoang e le phello ea Thomson.Motsoako oa li-conductor tse peli tse fapaneng kapa li-semiconductors li bitsoa thermocouple.
Kamoo li-Sensors tse hanyetsanang li sebetsang kateng
Boleng ba ho hanyetsa ha conductor bo fetoha le mocheso, 'me mocheso oa ntho e lokelang ho lekanyetsoa o baloa ka ho lekanya boleng ba ho hanyetsa.Sensor e entsoeng ke molao-motheo ona ke sensor ea mocheso oa ho hanyetsa, e sebelisoang haholo-holo bakeng sa mocheso oa mocheso oa -200-500 ° C.Tekanyo.Tšepe e hloekileng ke thepa e ka sehloohong ea tlhahiso ea ho hanyetsa mocheso, 'me thepa ea ho hanyetsa mocheso e lokela ho ba le litšobotsi tse latelang:
(1) Tekanyo ea mocheso oa ho hanyetsa e lokela ho ba kholo le e tsitsitseng, 'me ho be le kamano e ntle ea mela pakeng tsa boleng ba ho hanyetsa le mocheso.
(2) High resistivity, matla a fokolang a mocheso le lebelo la ho arabela ka potlako.
(3) Thepa e na le bokhoni bo botle ba ho ikatisa le boqapi, 'me theko e tlase.
(4) Lintho tsa lik'hemik'hale le tsa 'mele li tsitsitse ka har'a tekanyo ea tekanyo ea mocheso.
Hona joale, platinum le koporo ke tsona tse sebelisoang ka ho fetisisa indastering, 'me li entsoe ka mokhoa o tloaelehileng oa ho lekanya mocheso oa mocheso.
Ho nahanisisa ha u khetha sensor ea mocheso
1. Hore na maemo a tikoloho a ntho e lekantsoeng a na le tšenyo leha e le efe ho karolo ea ho lekanya mocheso.
2. Hore na mocheso oa ntho e lekantsoeng o hloka ho ngoloa, ho tšosoa le ho laoloa ka mokhoa o itekanetseng, le hore na o hloka ho lekanyetsoa le ho fetisoa ka thōko.3800 100
3. Tabeng eo mocheso oa ntho e lekantsoeng e fetohang ka nako, hore na sekhahla sa mocheso oa mocheso se ka finyella litlhoko tsa ho lekanya mocheso.
4. Boholo le ho nepahala ha tekanyo ea tekanyo ea mocheso.
5. Hore na boholo ba elemente ea ho metha mocheso bo loketse.
6. Theko e tiisitsoe le hore na e loketse ho e sebelisa.
Mokhoa oa ho qoba liphoso
Ha u kenya le ho sebelisa sensor ea mocheso, liphoso tse latelang li lokela ho qojoa ho netefatsa phello e ntle ea tekanyo.
1. Liphoso tse bakoang ke ho kenya ka mokhoa o sa lokelang
Ka mohlala, boemo ba ho kenya le ho kenya botebo ba thermocouple bo ke ke ba bonahatsa mocheso oa sebele oa sebōpi.Ka mantsoe a mang, thermocouple ha ea lokela ho kenngoa haufi haholo le monyako le ho futhumatsa, 'me botebo ba ho kenya e lokela ho ba bonyane makhetlo a 8 ho isa ho 10 bophara ba tube ea tšireletso.
2. Phoso ea ho hanyetsa mocheso
Ha mocheso o phahame, haeba ho na le lera la molora oa mashala holim'a tube e sireletsang 'me lerōle le khomaretsoe ho eona, ho hanyetsa mocheso ho tla eketseha le ho sitisa ho tsamaisa mocheso.Ka nako ena, boleng ba pontšo ea mocheso bo tlase ho feta boleng ba 'nete ba mocheso o lekantsoeng.Ka hona, bokantle ba tube ea tšireletso ea thermocouple bo lokela ho bolokoa bo hloekile ho fokotsa liphoso.
3. Liphoso tse bakoang ke ho fokola ha metsi
Haeba thermocouple e insulated, litšila tse ngata haholo kapa letsoai le lengata holim'a tube ea tšireletso le boto ea ho taka ea terata e tla etsa hore ho be le ts'oaetso e fokolang pakeng tsa thermocouple le lerako la sebōpi, e leng se tebileng haholoanyane mocheso o phahameng, o ke keng oa baka feela tahlehelo ea mocheso. matla a thermoelectric empa hape e hlahisa tšitiso.Phoso e bakiloeng ke sena ka linako tse ling e ka fihla Baidu.
4. Liphoso tse hlahisoang ke inertia ea mocheso
Phello ena e bonahala ka ho khetheha ha ho etsoa litekanyo tse potlakileng hobane mocheso oa mocheso oa thermocouple o etsa hore boleng bo bontšitsoeng ba metara bo sale ka mor'a phetoho ea mocheso o lekantsoeng.Ka hona, thermocouple e nang le electrode e fokolang ea mocheso le bophara bo fokolang ba tube ea tšireletso e lokela ho sebelisoa ka hohle kamoo ho ka khonehang.Ha tikoloho ea tekanyo ea mocheso e lumella, tube e sireletsang e ka ba ea tlosoa.Ka lebaka la tekanyo ea tekanyo, boholo ba ho fetoha ha mocheso o bonoang ke thermocouple bo nyane ho feta ba ho feto-fetoha ha mocheso oa sebōpi.Ha tekanyo ea litekanyo e le kholoanyane, e fokotsa boholo ba ho fetoha ha thermocouple le phapang e kholo ho tloha mocheso oa sebele oa sebōpi.
