I-thermistor, icandelo le-semicondcuctor, libonakaliswa kukungaxhathisi ngokuchaseneyo nokuzihlaziya ngobushushu.Ihlelwe kwiindidi ezimbini ezisekwe kubushushu obunelanga: iqondo lobushushu elilulo lokusebenza (i-PTC) ye-thermistor kunye neqondo elingalunganga le-PHC).I-thermisztor ye-NTC, eyaziwa ngokuba yimilinganiselo yawo yobushushu, ulawulo, kunye nobuchule bembuyekezo, ibonwa ngokubanzi njengomthombo wobushushu.Kwelinye icala, i-PTC ye-PTC, ngelixa ikwasetyenziselwa ukulinganiswa kobushushu kunye nolawulo, kabini njengento yokufudumeza kunye nemisebenzi ".Idibanisa iindima zento enobuthathaka, i-heater, kwaye itshintshe, izuze i-moniker "switch ye-shitrm".
Ukuhlala kwi-thermistor ye-NTC, ichazwa ngokuba ngamaqondo obushushu ayo anengqondo, efanekise ukuba ukuxhathisa kwayo kuncipha ukuba iqondo lobushushu liphuma.Lo mkhwa wenza izinto ze-NTC ezithandwayo kwiindlela zokuqala ezithambileyo, kunye nesekethe ezenzekelayo kunye nesekethe ezilawulayo kwizixhobo ezincinci zekhaya.Kwelinye icala, i-PTC ye-PTC ibonisa iqondo lobushushu elilungisiweyo, apho kuxhathisa amaqondo obushushu, kungoko ukusetyenziswa kwayo kwisekethe ezilawulayo.
I-thermistor ye-NTC yi-ceramic semiconductor, i-crystal enobuthathaka obunobuthathaka obuthathaka kwi-oxidey yentsimbi, i-manganese, i-cobalt, kunye ne-nickel.Ixabiso layo le-zero-mandla lokuchasa amandla inxulumene neqondo lobushushu.Eyona nto iphambili, i-thermistotor ibuthathaka ye-semicondcuctor, ihlengahlengisa ukuxhathisa kwayo ekuphenduleni kutshintsho lobushushu kwicandelo uqobo.
Ukugxila kubushushu obungalunganga (i-NTC) ye-thermistor, i-NTC yoMsebenzi-mali (RT) kubushushu obuthile (t) ichazwa njengexabiso lokunganyangeki phantsi kwe-DC yangoku apho ukusetyenziswa kwangoku kuncikho khona.Ukuba amandla ancitshisiwe, inqanaba lokutshintsha ukuxhathisa lihlala lingaphantsi kwe-0.1%.Impahla rhoqo (b), enye ipharamitha ephambili, ibalwa kusetyenziswa ifomula esekwe kubushushu obuthile (usebenzisa ubushushu obuthile (usebenzisa ubushushu obufanelekileyo k): b = ln (1 / T1).Ngokwesiqhelo kumiselwe kwi-T1 = 298.15k kunye ne-T2 = 323.15k okanye i-358.15k, i-B Ixabiso le-B lisuka kwi-2000 ukuya kwi-6000K.Ixabiso elikhulu le-B, ukuphakamisa ireyithi yokutshintsha kwentendi ye-1 ° C.
I-PROATION COORD (δ) imele amandla afunekayo yi-NTC ye-NTC yokwandisa iqondo lobushushu nge-1 ° C ngokuzifudumeza, ivalwe kwi-MW / ° C.Ibalwa yi-δ = v × i / t-t0).Okokugqibela, ixesha le-shirmal lihlala lihleli (τ) lixesha elifunekayo lokuba umlondolozi weqondo lobushushu i-63.2% umahluko phakathi kweqondo lokushisa i-T0 kunye neqondo lokugqibela le-T1 phantsi kwemizuzwana (s).
