NTC e emetse "Negative Temperature Coefficient". Li-thermistor tsa NTC ke li-resistant tse nang le mocheso o fokolang oa mocheso, ho bolelang hore khanyetso e fokotseha ka mocheso o ntseng o eketseha. E entsoe ka manganese, cobalt, nickel, koporo le li-oxide tse ling tsa tšepe e le lisebelisoa tsa mantlha ka ts'ebetso ea ceramic. Lisebelisoa tsena tsa tšepe tsa oxide li na le thepa ea semiconducting hobane li tšoana ka ho feletseng le lisebelisoa tsa semiconducting tse kang germanium le silicon ka tsela ea ho tsamaisa motlakase.

Haeba u batla ho fumana moeli o pakeng tsa motlakase o sa fellang le mocheso, o ka sebelisa potoloho e latelang:
Lisebelisoa tsa NTC thermistor
Ho latela semelo sa coefficient e fosahetseng ea thermistor ea NTC, e sebelisoa haholo maemong a latelang:
1. Matšeliso a mocheso oa li-transistors, li-IC, li-crystal oscillators bakeng sa lisebelisoa tsa puisano tsa mehala.
2. Temperature Sensing bakeng sa Batteries Rechargeable.
3. Matšeliso a Mocheso bakeng sa LCD.
4. Matšeliso a mocheso le ho utloa lisebelisoa tsa molumo oa koloi (CD, MD, tuner).
5. Matšeliso a mocheso bakeng sa lipotoloho tse sa tšoaneng.
6. Khatello ea inrush hona joale ka ho fetola phepelo ea motlakase le potoloho ea matla.
Litlhokomeliso bakeng sa tšebeliso ea thermistor ea NTC
1. Ela hloko mocheso o sebetsang oa thermistor ea NTC.
Le ka mohla u se ke ua sebelisa thermistor ea NTC ka ntle ho sebaka sa mocheso o sebetsang. Mocheso o sebetsang oa lihlopha tsa φ5, φ7, φ9, le φ11 ke -40~+150℃; mocheso o sebetsang oa letoto la φ13, φ15, le φ20 ke -40~+200℃.
2. Ka kopo hlokomela hore lithermitara tsa NTC li lokela ho sebelisoa tlas'a maemo a matla a matla.
Matla a phahameng a lekantsoeng a tlhaloso ka 'ngoe ke: φ5-0.7W, φ7-1.2W, φ9-1.9W, φ11-2.3W, φ13-3W, φ15-3.5W, φ20-4W
3. Litlhokomelo bakeng sa tšebeliso ea mocheso o phahameng le maemo a mongobo o phahameng.
Haeba thermistor ea NTC e hloka ho sebelisoa sebakeng sa mocheso o phahameng le mongobo o phahameng, mocheso oa mofuta oa sheath o lokela ho sebelisoa 'me karolo e koetsoeng ea sheath e sireletsang e lokela ho pepesehela tikoloho (metsi, mongobo), le karolo e qalang ea sheath. e ke ke ea kopana ka kotloloho le metsi le mouoane.
4. E ke ke ea sebelisoa khase e kotsi, tikoloho ea metsi.
Se ke oa e sebelisa sebakeng sa khase e senyang kapa sebakeng seo e tla kopana le li-electrolyte, metsi a letsoai, li-acids, alkalis le metsoako ea tlhaho.
5. Sireletsa lithapo.
U se ke ua otlolla le ho koba lithapo 'me u se ke ua sebelisa ho thothomela ho feteletseng, ho tšoha le khatello.
6. Lula hole le likarolo tsa elektronike tse hlahisang mocheso.
Qoba ho kenya lisebelisoa tsa elektroniki tse tloaetseng mocheso ho potoloha thermistor ea motlakase ea NTC, ho khothalletsoa ho sebelisa lihlahisoa tse nang le lithapo tse phahameng karolong e kaholimo ea leoto le kobehileng, 'me u sebelise thermistor ea NTC hore e be holimo ho feta likarolo tse ling tsa boto ea potoloho ho qoba ho futhumatsa. e amang tshebetso e tlwaelehileng ya dikarolo tse ding.
