NTC inomirira kuti “Negative Temperature Coefficient”. NTC thermistors inopikisa ine yakashata tembiricha coefficient, zvinoreva kuti kuramba kunodzikira nekuwedzera tembiricha. Yakagadzirwa nemanganese, cobalt, nickel, mhangura uye mamwe simbi oxides sezvinhu zvikuru zveceramic process. Izvi zvesimbi oxide zvinhu zvine semiconducting zvivakwa nekuti zvakafanana zvachose semiconducting zvinhu zvakaita segermanium nesilicon munzira yekuitisa magetsi. Iyi inotevera sumo yenzira yekushandisa uye chinangwa cheNTC thermistor mudunhu.
Kana iyo NTC thermistor ichishandiswa kuona tembiricha, kutarisa kana muripo, zvinowanzodikanwa kubatanidza chinopikisa munhevedzano. Kusarudzwa kwekukosha kwekupikisa kunogona kugadziriswa maererano nenzvimbo yekushisa inoda kuonekwa uye chiyero chezvino chinoyerera. Kazhinji, chinopikisa chine kukosha kwakafanana neyakajairwa tembiricha kuramba kweNTC ichabatanidzwa munhevedzano, uye ikozvino inoyerera kuburikidza inovimbiswa kuva diki zvakakwana kuti isazvidziye uye inokanganisa yekuona kurongeka.Chiratidzo chakaonekwa ndicho chikamu chevoltage paNTC thermistor. Kana iwe uchida kuwana yakawedzera mutsara curve pakati pechikamu chevoltage uye tembiricha, unogona kushandisa inotevera dunhu:
Iko kushandiswa kweNTC thermistor
Zvinoenderana nehunhu hweiyo negative coefficient yeNTC thermistor, inoshandiswa zvakanyanya mune zvinotevera zviitiko:
1. Tembiricha muripo we transistors, ICs, crystal oscillators for mobile communication equipment.
2. Tembiricha Sensing nokuda Rechargeable Mabhatiri.
3. Temperature Compensation yeLCD.
4. Tembiricha muripo uye sensing motokari odhiyo midziyo (CD, MD, tuner).
5. Kubhadhara kwekushisa kwemasekete akasiyana-siyana.
6. Kudzvinyirirwa kweinrush ikozvino mukushandura magetsi uye magetsi emagetsi.
Chengetedzo yekushandiswa kweNTC thermistor
1. Teerera kune tembiricha yekushanda yeNTC thermistor.
Usambofa washandisa iyo NTC thermistor kunze kweiyo tembiricha yekushanda. Kupisa kwekushanda kwe φ5, φ7, φ9, uye φ11 series ndeye -40~+150℃; tembiricha yekushanda ye φ13, φ15, uye φ20 series ndeye -40~+200℃.
2. Ndapota cherechedza kuti NTC thermistors inofanira kushandiswa pasi pemamiriro emagetsi emagetsi.
Iyo yakawanda yakarongerwa simba reiyo yega yega rondedzero ndeye: φ5-0.7W, φ7-1.2W, φ9-1.9W, φ11-2.3W, φ13-3W, φ15-3.5W, φ20-4W
3. Chengetedzo yekushandiswa mukupisa kwepamusoro uye nzvimbo dzakanyorova.
Kana iyo NTC thermistor ichida kushandiswa mukupisa kwakanyanya uye yakakwira humidity nharaunda, sheath type thermistor inofanirwa kushandiswa uye iyo yakavharwa sheath yekudzivirira inofanira kuratidzwa kune zvakatipoteredza (mvura, unyoro), uye chikamu chekuvhura chesheath hachizove chakanangana nemvura nemhepo.
4. Haikwanise kushandiswa mugasi rinokuvadza, nzvimbo yemvura.
Usashandise munzvimbo ine gasi rinoparadza kana munzvimbo iyo ichasangana ne electrolytes, mvura yemunyu, acids, alkalis, uye organic solvents.
5. Chengetedza waya.
Usatambanudza uye kupeta waya uye usashandise zvakanyanya vibration, kuvhunduka uye kumanikidza.
6. Ramba kure nekupisa-kuunza zvigadzirwa zvemagetsi.
Regedza kuisa zvinhu zvemagetsi zvinoita kupisa kwakatenderedza simba reNTC thermistor, Zvinokurudzirwa kushandisa zvigadzirwa zvine ma lead akakwira kumusoro kwetsoka yakakombama, uye shandisa NTC thermistor kuti ive yakakwirira kupfuura zvimwe zvikamu padhiketi redunhu kudzivirira kupisa kunokanganisa kushanda kwakajairika kwezvimwe zvikamu.
