I-NTC imele "i-Negative Temperature Coefficient".Ii-thermistors ze-NTC zizixhasi ezine-coefficient engalunganga yobushushu, nto leyo ethetha ukuba ukuxhathisa kuyancipha ngokunyuka kwamaqondo obushushu.Yenziwe nge-manganese, i-cobalt, i-nickel, ubhedu kunye nezinye ii-oxide zetsimbi njengezona zinto ziphambili ngenkqubo ye-ceramic.Ezi zixhobo ze-oxide zensimbi zineempawu ze-semiconducting ngenxa yokuba zifana ngokupheleleyo nezixhobo ze-semiconducting ezifana ne-germanium kunye ne-silicon kwindlela yokuqhuba umbane.Oku kulandelayo kukwazisa kwindlela yokusetyenziswa kunye nenjongo ye-NTC thermistor kwisekethe.
Xa i-thermistor ye-NTC isetyenziselwa ukukhangela ubushushu, ukubeka iliso okanye imbuyekezo, ngokuqhelekileyo kuyimfuneko ukudibanisa i-resistor kuthotho.Ukukhethwa kwexabiso lokuchasana kunokumiselwa ngokuhambelana nommandla wokushisa ofunekayo ukufunyanwa kunye nomlinganiselo wokuhamba ngoku.Ngokubanzi, i-resistor enexabiso elifanayo kunye nokumelana nobushushu obuqhelekileyo be-NTC iya kudibaniswa kuchungechunge, kwaye ikhoyo ngoku ihambayo iqinisekisiwe ukuba incinci ngokwaneleyo ukuphepha ukuzifudumeza kwaye ichaphazele ukuchaneka kokuchongwa. amandla ombane kwi-thermistor ye-NTC.Ukuba ufuna ukufumana igophe elingaphezulu phakathi kombane ophakathi kunye nobushushu, ungasebenzisa le sekethi ilandelayo:
Ukusetyenziswa kwe thermistor ye-NTC
Ngokophawu lwe-coefficient engalunganga ye-NTC thermistor, isetyenziswa ngokubanzi kwezi meko zilandelayo:
1. Imbuyekezo yobushushu be-transistors, i-ICs, i-crystal oscillators yezixhobo zokunxibelelana ngeselula.
2. UVavanyo lobushushu kwiibhetri eziTshajwa kwakhona.
3. Imbuyekezo yoBubushushu beLCD.
4. Imbuyekezo yobushushu kunye nokuziva kwisixhobo somsindo wemoto (CD, MD, tuner).
5. Imbuyekezo yobushushu kwiisekethe ezahlukeneyo.
6. Ukunyanzeliswa kwe-inrush current ekutshintsheni ukunikezelwa kwamandla kunye nombane wesiphaluka.
Izilumkiso zokusetyenziswa kwe thermistor ye-NTC
1. Nika ingqalelo kwiqondo lokushisa elisebenzayo le-NTC thermistor.
Ungaze usebenzise i-thermistor ye-NTC ngaphandle koluhlu lobushushu obusebenzayo.Ubushushu bokusebenza kwe-φ5, φ7, φ9, kunye nochungechunge lwe-φ11 ngu-40~+150℃;ubushushu bokusebenza kwe-φ13, φ15, kunye nochungechunge lwe-φ20 yi -40~+200℃.
2. Kucelwa uqaphele ukuba iithermitors ze-NTC mazisetyenziswe phantsi kweemeko zombane ezireyithiweyo.
Amandla alinganisiweyo aphezulu kwinkcazo nganye: φ5-0.7W, φ7-1.2W, φ9-1.9W, φ11-2.3W, φ13-3W, φ15-3.5W, φ20-4W
3. Izilumkiso zokusetyenziswa kwiqondo lokushisa eliphezulu kunye neendawo zokufuma eziphezulu.
Ukuba i-thermistor ye-NTC kufuneka isetyenziswe kwindawo yokushisa ephezulu kunye nokufuma okuphezulu, i-thermistor yohlobo lwe-sheath kufuneka isetyenziswe kwaye indawo evaliweyo ye-sheath yokukhusela kufuneka ibonakaliswe kwindawo (amanzi, ukufuma), kunye nenxalenye yokuvula ye-sheath. ayizukudibana ngqo namanzi kunye nomphunga.
4. Ayinakusetyenziswa kwirhasi eyingozi, kwindawo elulwelo.
Ungayisebenzisi kwindawo yerhasi eyonakalisayo okanye kwindawo apho iya kuthi idibane ne-electrolytes, amanzi anetyuwa, iiasidi, iialkali, kunye nezinyibilikisi eziphilayo.
5. Khusela iingcingo.
Musa ukugqithisa kwaye ugobe iingcingo kwaye ungasebenzisi ukungcangcazela okugqithisileyo, ukothuka kunye noxinzelelo.
6. Zigcine kude nezinto zombane ezivelisa ubushushu.
Kuphephe ukufaka izixhobo ze-elektroniki ezithanda ubushushu kumbane we-NTC thermistor, kuyacetyiswa ukuba kusetyenziswe iimveliso ezinokhokelo oluphezulu kwindawo ephezulu yonyawo olugobileyo, kwaye usebenzise i-NTC thermistor ukuba ibe phezulu kunezinye izinto kwibhodi yesekethe ukunqanda ukufudumeza. echaphazela ukusebenza okuqhelekileyo kwamanye amacandelo.
