Kei roto i nga whakamaarama te whakamaarama whakamaarama pai (PTC) me nga whakamaarama whakarea pāmahana kino (NTC), me nga wera wera nui (CTRS).
1.PTC werawera
Ko te PTC (Poitive Temperature CoeffiCient) he thermistor, he rauemi ranei he pai te whakarea pāmahana me te piki koi o te aukati i tetahi pāmahana.Ka taea te whakamahi hei pūoko pāmahana tonu.Ko te papanga he tinana kua whakahiatohia me te BaTiO3, SrTiO3, PbTiO3 ranei te waahanga matua, me te taapiri i nga waikura o Mn, Fe, Cu me Cr e whakanui ana i te whakarea o te pāmahana parenga pai me etahi atu taapiri e mahi ana i etahi atu mahi.Ko te rauemi i hanga e te tikanga uku noa, ka sintered i te pāmahana teitei ki te hanga konukawata titanate me tona otinga totoka āhua-conductive.No reira ka whiwhihia nga rauemi waiariki me nga ahuatanga pai.He rereke te whakarea pāmahana me te ira Curie i runga i te hanganga me nga tikanga whakahiato (ina koa te pāmahana whakamatao).
I puta te PTC thermistor i te rautau 20th, ka taea te whakamahi PTC thermistor mo te inenga me te mana whakahaere i roto i te umanga, ka whakamahia hoki mo te kitenga o te pāmahana me te whakaritenga o tetahi waahanga o te motuka, engari he maha ano nga taputapu a-iwi, penei i te mana whakahaere te whakamahana wai inamata te wera o te wai, te whakamahana hau me te pāmahana rokiroki makariri, te whakamahi i tana ake whakamahana mo te tātari hau me te anemometer me etahi atu waahanga.
Ko te thermistor PCT te mahi o te pupuri i te pāmahana i roto i te awhe motuhake, me te mahi hoki i te mahi whakawhiti.Ma te whakamahi i tenei ahuatanga whakawera wera hei puna whakamahana, ka taea hoki e ia te mahi hei whakamarumaru wera rawa mo nga taputapu hiko.
2.NTC weariki
Ko te Waahanga Pawera Tohara (NTC) e tohu ana ki tetahi ahuatanga weariki me nga rawa he whakarea pāmahana kino na te mea ka tino heke te parenga i te pikinga o te pāmahana.Ko te rauemi he karaika semiconducting i hangaia i te rua, neke atu ranei nga waikura whakarewa penei i te manganese, te parahi, te silicon, te cobalt, te rino, te nickel, me te zinc, he mea whakauru katoa, he mea hanga, ka whakahiatotia hei whakaputa i te waiariki me te whakarea pāmahana kino (NTC). ).
Ko te wahanga whanaketanga o te NTC thermistor: mai i tona kitenga i te rautau 19th ki tona whanaketanga i te rau tau 20, kei te whakapai tonu.
Ko te tika o te ine ine wera ka taea te tae ki te 0. 1 ℃, ka iti iho i te 10s te wa whakamaarama.Ehara i te mea e tika ana mo te inemahana whare witi, engari ka taea hoki te whakamahi ki te rokiroki kai, rongoa me te hauora, ahuwhenua putaiao, moana, puna hohonu, teitei teitei, te ine pāmahana hukapapa.
3.CTR thermistor
Critical Temperature Thermistor CTR (Critical Temperature Resistor) he ahuatanga rerekee te parenga kino, i tetahi pāmahana, ka tino heke te parenga me te pikinga o te pāmahana me te nui o te whakarea pāmahana kino.Ko te mea hanga ko te vanadium, te barium, te strontium, te ūkuikui me etahi atu huānga o te tinana kua whakauruhia, he semiconductor ahua-karaihe, e mohiotia ana ko CTR mo te whakamaarama karaihe.Ka taea te whakamahi CTR hei whakaoho mana pāmahana me etahi atu tono.
Ka taea hoki te whakamahi i te Thermistor hei huānga iahiko hiko mo te utu whakamahana hiko hiko me te utu pāmahana o te mutunga makariri thermocouple.Ka taea te whakahaere mana whiwhi aunoa ma te whakamahi i te ahua whakamahana-whaiaro o te thermistor NTC, ka taea te hanga i te ara iahiko whakapumautanga kaha, ara iahiko whakaroa me te ara iahiko tiaki o RC oscillator.Kei te nuinga whakamahia PTC thermistor i roto i te taputapu hiko tiaki overheating, whakapākore tānga, te pāmahana tamau, mana whiwhi aunoa, tīmata nekeneke, wā roa, tae TV demagging aunoa, whakaoho ahi me te pāmahana utu, etc.
