Imikorere ya Thermistor

1. Ukurikije coefficente itandukanye yo guhindura imitekerereze, thermistors igabanijwemo ibyiciro bibiri:

Ubwoko bumwe bwitwa ubushyuhe bwiza coefficient thermistor (PTC), agaciro kayo ko kwihanganira kwiyongera hamwe nubushyuhe;

Ubundi bwoko bwitwa Negative Temperature Coefficient Thermistor (NTC), agaciro kayo ko kugabanuka kugabanuka hamwe nubushyuhe bwiyongera.

2. Ihame ryakazi rya Thermistor

1) Ubushyuhe bwiza bwa coefficient thermistor (PTC)

Ubusanzwe PTC ikozwe muri barium titanate nkibikoresho byingenzi, kandi umubare muto wibintu bidasanzwe byubutaka byongewe kuri barium titanate, kandi bikozwe nubushyuhe bwo hejuru. Barium titanate ni polycrystalline. Hariho ibice bya kristu yimbere hagati ya kristu y'imbere na kristu. Iyo ubushyuhe buri hasi, electroni ziyobora zirashobora kwambuka byoroshye ibice byimbere kubera amashanyarazi yimbere. Muri iki gihe, agaciro kayo ko guhangana kazaba nto. Iyo ubushyuhe buzamutse, umurima w'amashanyarazi w'imbere uzasenywa, biragoye ko electroni ziyobora zambuka ibice, kandi agaciro ko guhangana kazamuka muri iki gihe.

2) Ubushyuhe bubi coefficient thermistor (NTC)

Ubusanzwe NTC ikozwe mubikoresho bya oxyde nka cobalt oxyde na nikel oxyde. Ubu bwoko bwicyuma cya oxyde ifite electron nke nu mwobo, kandi agaciro kayo ko guhangana kuzaba hejuru. Iyo ubushyuhe buzamutse, umubare wa electron nu mwobo imbere uziyongera kandi agaciro ko kurwanya kugabanuka.

3. Ibyiza bya thermistor

Ubukangurambaga bukabije, coefficente yubushyuhe bwa thermistor iruta inshuro 10-100 kurenza icyuma, kandi irashobora kumenya ihinduka ryubushyuhe bwa 10-6 ℃; ubugari bwubushyuhe bugari, ibikoresho byubushyuhe busanzwe birakwiriye -55 ℃ ~ 315 ℃, ibikoresho byubushyuhe bwo hejuru bikwiranye nubushyuhe Hejuru ya 315 ℃ (kuri ubu hejuru irashobora kugera 2000 ℃), igikoresho cy'ubushyuhe buke gikwiranye na -273 ℃ ~ -55 ℃; ni ntoya mubunini kandi irashobora gupima ubushyuhe bwumwanya izindi termometero zidashobora gupima

4. Gukoresha thermistor

Ikoreshwa ryingenzi rya thermistor ni nkibintu byerekana ubushyuhe, kandi ubushuhe bwo kumenya ubushyuhe bukoresha ubushuhe hamwe nubushuhe bubi, ni ukuvuga NTC. Kurugero, ibikoresho bisanzwe bikoreshwa murugo, nkibiteka byumuceri, abateka induction, nibindi, byose bikoresha thermistors.
