Imikorere ya Thermistor

1. Thermistor ni umurwanya ibikorwa bidasanzwe, kandi kurwanya agaciro kahinduka ubushyuhe. Dukurikije impinduka zinyuranye zo guhinduka, abarozi bagabanijwemo ibyiciro bibiri:

Ubwoko bumwe bwitwa ubushyuhe bwiza bwa theermistor (PTC), agaciro kabo kwiyongera kwiyongera nubushyuhe;

Ubundi bwoko bwitwa ubushyuhe bukabije bwa Tranrside (NTC), agaciro kabo ko kurwanya garagaza ubushyuhe.

2. Ihame ryabo mukorana

1) Ubushyuhe bwiza bwa theermistor (PTC)

PTC muri rusange ikozwe muri bariimi Titanate nkibikoresho nyamukuru, kandi umubare muto wisi wongerewe kuri bariyo Titante, kandi ukozwe nubushyuhe bwinshi. Barium Titanate ni ibikoresho bya Polycrystalline. Hano hari umurongo wa kirisiti hagati ya kirisiti yimbere na kristu. Iyo ubushyuhe ari buke, electron yo kuyobora irashobora kwambuka byoroshye umurongo kubera amashanyarazi imbere. Muri iki gihe, agaciro kayo kirwanya bizaba bito. Iyo ubushyuhe buzamutse, umurima w'amashanyarazi w'imbere uzarimburwa, biragoye ku byaha bya electron yo kunyuramo kugira ngo bambure umurongo, kandi agaciro karwanya bizamuka muri iki gihe.

2) Ubushyuhe bubi bwa Tormistor (NTC)

NTC muri rusange ikozwe mubikoresho by'icyuma nka cobalt oxide na nikel okiside. Ubu bwoko bwicyuma bufite electron nkeya ninzoka, kandi agaciro kayo karimo kuba hejuru. Iyo ubushyuhe buzamutse, umubare wa electron n umwobo imbere uziyongera kandi agaciro ko kurwanya bizagabanuka.

3. Ibyiza bya Thermistor

Ubushishozi buhanitse, ubushyuhe bwubushyuhe bwa Thermistor burenze inshuro 10-100 kurenza iyi cyuma, kandi irashobora kubona ubushyuhe bwa 10-6 ℃; Ubushyuhe bwinshi bwo gukora ubushyuhe, ibikoresho bisanzwe byubushyuhe birakwiriye -55 ℃ ~ 315 ℃, ubushyuhe bwinshi bukwiranye nubushyuhe buri 2000 ℃) ni nto mubunini kandi irashobora gupima ubushyuhe bwumwanya abandi bamorometero badashobora gupima

4. Gusaba Thermistor

Gushyira mubikorwa bya thermistor ni nkibintu byo kumenya ubushyuhe, nubushyuhe bwubushyuhe bukoresha umukunzi ufite ubushyuhe bubi, ni ukuvuga NTC. Kurugero, mubisanzwe bikoreshwa ibikoresho byo murugo, nkumuceri uteka, abateka ba kwishoramo, nibindi, bose bakoresha THERMistors.
