Ni ubuhe bwoko bwa NTC?

Ni ubuhe bwoko bwa NTC?

Kugira ngo dusobanukirwe n'imikorere hamwe na porogaramu ya NTC Ubushyuhe bwa NTC, tugomba kubanza kumenya icyo NTC Thermistor ari.
Uburyo NTC Ubushyuhe bwa NTC bukora gusa
Abayobora bashyushye cyangwa abashinzwe gususurutsa ni abo bakomokamo ibikoresho bya elegitoroniki hamwe na coefficiere mbi (NTC kuri bugufi). Niba ubungurutse ibinyuramo bigize ibice, kurwanya kwabo kugabanuka hamwe nubushyuhe. Niba ubushyuhe bwibidukikije butonyanga (urugero: ibice byo kwibiza), ibice, kurundi ruhande, reba no kongera kurwanya. Kubera iyi myitwarire idasanzwe, impuguke zivuga kandi ko NTC irwanya nka NTC Thermistor.

Kurwanya amashanyarazi bigabanuka iyo electrons yimuka
Abakoba muri NTC bagizwe n'ibikoresho bya Semiconductor, imikorere yaya muri rusange iri hagati y'abatwara amashanyarazi n'amashanyarazi. Niba ibice bishyuha, electron ikuraho atome ya kato. Bava mu mwanya wabo mu miterere no gutwara amashanyarazi kurushaho. Igisubizo: Hamwe n'ubushyuhe, abarozi bakora amashanyarazi neza - kurwanya amashanyarazi yabo agabanuka. Ibigize bikoreshwa, mubindi, nkumushumba, ariko kubwibi bigomba guhuzwa ninkomoko ya voltage hamwe na ammeter.

Gukora hamwe numutungo wabayobora bashyushye kandi bakonje
Umurwanya NTC arashobora kubyitwaramo intege nke cyangwa, mubice bimwe, cyane cyane guhinduka mubushyuhe bwimbonera. Imyitwarire yihariye ahanini biterwa no gukora ibice. Muri ubu buryo, abatanga bahuza umubare uvanga oxide cyangwa doupide yicyuma kubihe byifuzwa. Ariko imitungo yibigize irashobora kandi guterwa nibikorwa byo gukora ubwabyo. Kurugero, binyuze mubirimo bya ogisijeni mukirere cyo kurasa cyangwa igipimo cyumuntu ku giti cye cyibintu.

Ibikoresho bitandukanye byo Kurwanya NTC
Ibikoresho byiza bya semiconductor, semiconduct smoumiconduct cyangwa ibyuma bya Metallic bikoreshwa kugirango amarebera yerekana imyitwarire yabo iranga. Aba nyuma basanzwe bagizwe n'icyuma (ibice by'ibyuma na ogisijeni) bya Manganese, Nickel, Coabase, icyuma cyangwa titanium. Ibikoresho bivanze n'abakozi bashinzwe guhambire, bakandamijwe kandi baracumuye. Abakora bashyushya ibikoresho fatizo bitewe numuvuduko mwinshi kuburyo abakozi bakora imirimo hamwe nibiranga byifuzwa.

Ibiranga ibisanzwe bya Thermistor Urebye
Kurwanya NTC biraboneka mu gihe cya OFM imwe muri Ogohms 100. Ibice birashobora gukoreshwa kuva gukuramo 60 kugirango wongere impamyabumenyi ya selisi 200 kandi igere ku kwihanganira 0.1 kugeza 20%. Ku bijyanye no guhitamo thermistor, ibipimo bitandukanye bigomba kwitabwaho. Kimwe mu by'ingenzi ni imyigaragambyo yo kurwanya nomi. Irerekana agaciro ko kurwanya ubushyuhe bwatanzwe (mubisanzwe selisiges 25) kandi irangwa numurwa mukuru r nubushyuhe. Kurugero, R25 kubibazo byo kurwanya dogere 25. Imyitwarire yihariye kubushyuhe butandukanye nayo irakenewe. Ibi birashobora kugaragazwa hamwe nimbonerahamwe, formula cyangwa ibishushanyo kandi bigomba guhuza rwose nibisabwa. Ibindi biranga indangagaciro za NTC bifitanye isano no kwihanganira kimwe nubushyuhe hamwe nibigabanya imipaka.

Ibice bitandukanye byo gusaba NTC Kurwanya
Kimwe na PTC umurwanya PTC, umurwanya NTC nawo ukwiranye no gupima ubushyuhe. Guhindura agaciro gahinduka bitewe nubushyuhe bwibidukikije. Kugirango tutibeshya ibisubizo, kwishyuza bigomba kugarukira bishoboka. Ariko, kwishyuza mugihe cyubu birashobora gukoreshwa kugirango ugabanye inrush. Kuberako inyongera ya NTC ikonje nyuma yo guhinduranya ibikoresho byamashanyarazi, kuburyo rero ubanza gutemba. Nyuma yigihe runaka mubikorwa, Thermistor ashyushya, amashanyarazi atemba amashanyarazi aratonyanga no gutembera. Ibikoresho byamashanyarazi bigera kumikorere yabo byuzuye muri ubu buryo mugihe runaka gutinda.

Kurwanya NTC bikora amashanyarazi ububi ahantu hake. Niba ubushyuhe bwibidukikije bwiyongera, imyigaragambyo yiswe abayobora bashyushye bagabanuka cyane. Imyitwarire idasanzwe ya Semiconductor yibanze irashobora gukoreshwa cyane cyane gupima ubushyuhe, kugirango ushireho imipaka cyangwa kurema ibintu bitandukanye
