Umsebenzi we-thermistor

I-1. Umthendeleko ngumsebenzi wokurhoxa owenziwe ngezinto ezikhethekileyo, kwaye ixabiseke ngakumbi ixabiso lobushushu. Ngokutsho kwendlela eyahlukileyo yokutshintsha kotshintsho, abathengisi bobutsha bahlulwe baba ziindidi ezimbini:

Uhlobo olunye lubizwa ngokuba yiqondo elifanelekileyo lobushushu obufanelekileyo (PTC), ixabiso lalonyuswa ngobushushu;

Olunye uhlobo lubizwa ngokuba yi-thermistor yeqondo elingalunganga (i-NTC), ixabiso lakhe lincipha ngokukhulisa ubushushu obukhulayo.

I-2. Umgaqo oSebenzayo we-Whermistor

I-1) iqondo lobushushu elifanelekileyo le-thermistor eyongezelelweyo (PTC)

I-PTC yenziwa ngenxa ye-rium izishumi njengeyona nto iphambili, kwaye inani elincinci lezinto ezinqabileyo zomhlaba zongezwa kwi-Barium Titium Time, kwaye yenziwa lizonke. I-Barium Titatate yimpahla yePolycrystalline. Kukho isinxibelelanisi se-crystal phakathi kwekristale yangaphakathi kunye nekristale. Xa iqondo lobushushu liphantsi, ii-elektroni ezisebenzayo zinokuwela ngokulula i-sulticle ye-pritucle ngenxa yendawo yombane yangaphakathi. Ngeli xesha, ixabiso laso lokuxhathisa liya kuba lincinci. Xa iqondo lobushushu liyanyuka, intsimi yombane yangaphakathi iya kutshatyalaliswa, kunzima ukuba ii-elektroni zokuqhuba ziwele i-sucture, kwaye ixabiso lokuchasana liya kunyuka ngeli xesha.

2) Iqondo lobushushu elingalunganga

I-NTC isebenza ngokubanzi kwezixhobo ze-ox zentsimbi ezifana neCobalt Oxide kunye ne-nickel oxide. Olu hlobo lwe-oxideide lunee-elektroni ezincinci kunye nemingxunya, kwaye ixabiso laso lingaphezulu. Xa iqondo lobushushu liphuma, inani lee-elektroni kunye nemingxunya ngaphakathi baya kukhula kwaye ixabiso lokuchasana liya kuncipha.

I-3. Izibonelelo ze-thermistor

Ubuntununtunu obuphezulu, ubushushu obusebenzeleyo bomthendeleko bungaphezulu kwe-10-100 amatyeli obukhulu kuneso sensimbi, kwaye unokufumana utshintsho lobushushu lwe-10-6 ℃; Uluhlu lobushushu olubanzi lokusebenza, izixhobo zeqondo lobushushu eziqhelekileyo zilungele -55 ℃ ~ 315 ℃, izixhobo zeqondo lobushushu eziphezulu zilungele i-2000 ℃), isixhobo esisezantsi seqondo eliphantsi lilungele i-2000 ℃ ~ -55 ℃; Incinci ngokobukhulu kwaye inokulinganisa ubushushu besithuba esingakwaziyo ukulinganisa

4. Ukusetyenziswa kwe-thermistor

Ukusetyenziswa kwe-thermistor kuyinto yokufunyanwa kwamaqondo, kunye nokufunyanwa kweqondo lobushushu kudla ngokusebenzisa i-thermistor enobushushu obungalunganga, oko kukuthi, i-NTC. Umzekelo, izixhobo eziqhelekileyo zekhaya ezixhaphakileyo, ezinjengeerice ezipholileyo, ii-coadshers, njl njl.
