Yintoni i-NTC yobushushu?

Ukuqonda umsebenzi kunye nokusetyenziswa kweSensor ye-NTC, kufuneka kuqala sazi ukuba yintoni i-thermistor yomhlaba.
I-NTC ye-NTC ye-NTC ichazwa njani
Abaqhubi abashushu okanye abaqhubi abafudumeleyo ngabahlali boqikelelo ngamaqondo obushushu amaqondo obushushu (i-NTC yefutshane). Ukuba ihamba ngokuhamba ngamacandelo, ukumelana kwazo kuncitshiswa ngokwanda kwamaqondo obushushu. Ukuba amaqondo obushushu ahleliweyo (umz. Kwimikhono yokuntywila), amacandelo, kwelinye icala, asabele ngokuthi ngokuchaseneyo nokuxhathisa. Ngenxa yale nto yokuziphatha ekhethekileyo, iingcali zikwabhekisa kumthi wokurhoxisa i-NTC njengommeli we-NTC.

Ukuxhathisa kombane kuncipha xa i-elektroni ihamba
Abaqeqeshi be-NTC baqukethe izixhobo ze-semicondctor, ukuqhubela phambili okukhoyo kwabaqhubi bombane nabangaqhubi bombane. Ukuba izinto zibubushushu, ii-elektroni zakhulula kwiiatom ze-lattice. Bashiya indawo yabo kwisakhiwo kunye nezothutho ngakumbi. Isiphumo: Ngokukhulisa ubushushu esandayo, abathengisi baqhuba umbane kakhulu - ukumelana nombane kuyancipha. Izinto ezisetyenziswayo, phakathi kwezinye izinto, njengamaqondo ezinzwa, kodwa oku kufuneka zidityaniswe kumthombo wevoltage kunye ne-ammeter.

Ukwenziwa kunye neepropathi zabaqhubi abashushu nababandayo
I-NTC Shrisela ingenza buthathaka kakhulu okanye, kwiindawo ezithile, ngamandla kakhulu ukutshintsha amaqondo obushushu afanelekileyo. Ukuziphatha okuthile ngokusisiseko kuxhomekeke ekwenzeni amacandelo. Ngale ndlela, abavelisi batshintsha umlinganiso wokuxuba ii-oxide okanye ukucocwa kwee-oxide zentsimbi kwiimeko ozifunayo. Kodwa iipropathi zezinto zinokuphenjelelwa yinkqubo yokwenza imveliso ngokwayo. Umzekelo, ngomxholo weoksijini kwindawo yokudubula okanye inqanaba lokuphola kwezinto.

Izixhobo ezahlukeneyo ze-NTC
Izixhobo ezimsulwa ze-semicondcuctor, i-semicondsuctors okanye izabelo zentsimbi zisetyenziselwa ukuqinisekisa ukuba ii-thermistors zibonisa indlela abaziphatha ngayo. Ele ndlela idla ngokuhambelana ne-oxidel yentsimbi (i-quagend) ye-manganese, i-nickel, i-cobalt, intsimbi, i-titanium okanye i-titanium okanye i-titanium okanye i-titanium okanye i-titanium okanye i-titanium okanye i-titanium okanye i-titanium okanye i-titanium okanye i-titanium okanye i-titanium okanye i-titanium okanye i-titanium okanye i-titanium okanye i-titanium okanye i-titanium okanye i-titanium. Izixhobo zixutywe neearhente zokubopha, zicinezelwe kwaye zenziwe. Abavelisi bafudusele izixhobo ezingaphantsi komhlaba phantsi koxinzelelo oluphezulu ukuya kuthi ga ngoku ukuba kudalwe izinto ezinqwenelekayo.

Iimpawu eziqhelekileyo ze-thermistor kwi-GORMP
I-NTC Drivent ifumaneka kwi-ranges ukusuka kwi-OHM ukuya kwi-100 megohims. Amacandelo anokusetyenziswa kwi-60 ukuya kwi-200 degrees Celsius kwaye afezekise iifolda ze-0,1 ukuya kwi-20 pesenti. Xa kufikwa ekukhetheni i-thermistor, iiparameter ezahlukeneyo kufuneka zithathelwe ingqalelo. Enye yezona zinto zibalulekileyo kukuphikisana nokuthintelwa. Ibonisa ixabiso lokuchasana neqondo lobushushu elinikiweyo (ngesiqhelo ngama-25 demprees Celsius) kwaye iphawulwe ngemali enkulu kunye nobushushu. Umzekelo, i-R25 yexabiso lokuchasana ne-25 devrees Celsius. Ukuziphatha okuthile kubushushu obahlukeneyo kuyahambelana nawo. Oku kunokuchazwa ngeetafile, iifomula okanye imizobo kwaye kufuneka utshatise ngokupheleleyo isicelo esifunayo. Ixabiso elifanayo lokuzibamba labaphathi be-NTC inxulumene nokuzalelwa kunye nobushushu obuthile kunye nemida yevolthi.

Iinkalo ezahlukeneyo zesicelo somthi we-NTC
Njengomthi we-PTC, i-PTC yokuyeka i-NTC ikwalungele ukulinganiselwa kobushushu. Utshintsho lwexabiso lokuphiliswa luxhomekeke kwiqondo lobushushu. Ukulungiselela ukungazibubulisi iziphumo, ukuzifudula kuya kufuneka kuphakanyelwe kangangoko kunokwenzeka. Nangona kunjalo, ukuzifudumeza ngexesha lokuhamba okungekabikho kusetyenziselwa ukunciphisa umda wangoku. Ngenxa yokuba isitali se-NTC siyabanda emva kokutshintsha izixhobo zombane, ukuze nje kuqukuqela nje okuncinci okokuqala. Emva kwethuba lokusebenza, i-thermistotor iyabetha, amathontsi ombane axhathise kwaye ukuhamba okuthe kratya. Izixhobo zombane zokufezekisa intsebenzo yazo epheleleyo ngale ndlela kunye nokulibaziseka kwexesha elithile.

I-NTC Driver iqhuba ngombane ngokugqibeleleyo amaqondo obushushu asezantsi. Ukuba ubushushu obuvakalayo buyanda, ukuxhathisa kwabaqhubi abafudumeleyo bayaphulukana. Ukuziphatha okhethekileyo kwezinto ze-semiconductor kunokusetyenziswa ngokuyintloko kumgangatho wobushushu, ukunqongophala komda wangoku okanye ukulibazisa ucalucalulo
