Ubushyuhe burimo ubushyuhe bwiza (PTC) hamwe nubushyuhe bubi (NTC), hamwe nubushyuhe bukabije (CTRS).
1.PTC thermistor
Ubushyuhe Bwiza CoeffiCient (PTC) ni ibintu bya termistor cyangwa ibintu bifite coeffisente yubushyuhe bwiza kandi byiyongera cyane muburwanya mubushyuhe runaka.Irashobora gukoreshwa nkicyuma gihoraho.Ibikoresho ni umubiri wacumuye hamwe na BaTiO3, SrTiO3 cyangwa PbTiO3 nkigice cyingenzi, kandi ukongeraho na oxyde ya Mn, Fe, Cu na Cr byongera coeffisiyoneri yubushyuhe bwiza hamwe nibindi byongera bigira uruhare runini.Ibikoresho byakozwe muburyo busanzwe bwa ceramic kandi bigacumurwa mubushyuhe bwo hejuru kugirango platine titanate hamwe nigisubizo cyacyo gikomeye.Gutyo ibikoresho bya thermistor bifite ibimenyetso byiza birabonetse.Ubushyuhe bwa coefficient hamwe nubushyuhe bwa Curie buratandukana nibigize hamwe nicyaha (cyane cyane ubushyuhe bukonje).
Ubushyuhe bwa PTC bwagaragaye mu kinyejana cya 20, Ubushyuhe bwa PTC burashobora gukoreshwa mu gupima ubushyuhe no kugenzura inganda, bukoreshwa no kumenya ubushyuhe no kugenzura igice cy’imodoka, ariko kandi n’ibikoresho byinshi bya gisivili, nko kugenzura u ako kanya ubushyuhe bwamazi yubushyuhe bwamazi, icyuma gikonjesha hamwe nubushyuhe bukonje, gukoresha ubushyuhe bwacyo bwite bwo gusesengura gaze na anemometero nibindi.
PCT thermistor ifite imikorere yo kugumana ubushyuhe murwego runaka, kandi ikagira uruhare rwo guhinduranya.Ukoresheje ubu bushyuhe bwo kurwanya ubushyuhe buranga nkubushyuhe, burashobora kandi kugira uruhare mukurinda ubushyuhe bukabije kubikoresho byamashanyarazi.
2.NTC thermistor
Ubushuhe bubi CoeffiCient (NTC) bivuga ibintu bya thermistor nibintu bifite coeffisente yubushyuhe bubi kuko ubukana bugabanuka cyane uko ubushyuhe buzamuka.Ibikoresho ni ceramic ya semiconducte ikozwe mu byuma bibiri cyangwa byinshi bya oxyde nka manganese, umuringa, silikoni, cobalt, icyuma, nikel, na zinc, bivanze rwose, bikozwe, kandi bicumura kugirango bibyare ubushyuhe hamwe nubushyuhe bubi (NTC) ).
Icyiciro cyiterambere cya NTC thermistor: kuva yavumburwa mu kinyejana cya 19 kugeza iterambere ryacyo mu kinyejana cya 20, iracyatunganywa.
Ubusobanuro bwa thermistor thermometer burashobora kugera kuri 0. 1 ℃, kandi igihe cyo kumva ubushyuhe gishobora kuba munsi ya 10s.Ntibikwiye gusa kubipimo bya termometero, ariko birashobora no gukoreshwa mububiko bwibiryo, ubuvuzi nubuzima, ubuhinzi bwa siyansi, inyanja, iriba ryimbitse, ubutumburuke buke, gupima ubushyuhe bwa glacier.
3.CTR thermistor
Ubushyuhe bukabije bwa Thermistor CTR (Critical Temperature Resistor) ifite ihinduka ryimiterere ihindagurika iranga, ku bushyuhe runaka, kurwanya biragabanuka cyane hamwe no kwiyongera kwubushyuhe kandi bifite coeffisiyeti nini yubushyuhe.Ibikoresho byahimbwe ni vanadium, barium, strontium, fosifore nibindi bintu bigize umubiri uvanze wacumuye, ni kimwe cya kabiri cyikirahure cyitwa semiconductor, kizwi kandi nka CTR kuri thermistor.CTR irashobora gukoreshwa nkubushyuhe bwo kugenzura ubushyuhe nibindi bikorwa.
Thermistor irashobora kandi gukoreshwa nkibikoresho bya elegitoronike yumuzunguruko wibikoresho byubushyuhe bwumuzunguruko hamwe nubushyuhe bwubushyuhe bwa thermocouple impera ikonje.Igenzura ryunguka ryikora rishobora kugerwaho ukoresheje ubushyuhe bwo kuranga ubushyuhe bwa NTC, hamwe na amplitude stabilisation yumuzunguruko, gutinda kumuzunguruko no kurinda imiyoboro ya RC oscillator irashobora kubakwa.Ubushuhe bwa PTC bukoreshwa cyane cyane mubikoresho byamashanyarazi birinda ubushyuhe bukabije, relay itagira aho ihurira, ubushyuhe burigihe, kugenzura inyungu byikora, gutangira moteri, gutinda igihe, ibara rya tereviziyo yerekana amashanyarazi, gutabaza umuriro nindishyi zubushyuhe, nibindi.
