Thermistors sun haɗa da madaidaicin ƙimar zafin jiki (PTC) da ƙarancin zafin jiki mara kyau (NTC), da ma'aunin zafin jiki mai mahimmanci (CTRS).
1.PTC thermistor
Ingantattun Zazzabi CoeffiCient (PTC) wani abu ne na thermistor ko kayan da ke da ingantaccen yanayin zafin jiki da haɓakar juriya a wani zazzabi.Ana iya amfani da shi azaman firikwensin zafin jiki akai-akai.Kayan abu shine jikin da aka yi da shi tare da BaTiO3, SrTiO3 ko PbTiO3 a matsayin babban sashi, kuma yana ƙara oxides na Mn, Fe, Cu da Cr waɗanda ke ƙara ingantaccen ƙarfin juriya na juriya da sauran abubuwan da ke taka wasu ayyuka.An samar da kayan ta hanyar tsarin yumbu na gama gari kuma an ƙera shi a babban zafin jiki don yin titanate na platinum da ingantaccen bayani mai ƙarfi.Don haka ana samun kayan thermistor tare da halaye masu kyau.Matsakaicin yanayin zafin jiki da yanayin yanayin Curie sun bambanta tare da abun da ke ciki da yanayin ɓacin rai (musamman yanayin sanyi).
PTC thermistor ya bayyana a cikin karni na 20, ana iya amfani da PTC thermistor don auna zafin jiki da sarrafawa a cikin masana'antu, kuma ana amfani dashi don gano yanayin zafin jiki da tsarin wani ɓangaren mota, amma har ma da babban adadin kayan aikin jama'a, kamar kula da Nan take zafin ruwa mai dumama ruwa, kwandishan da zafin jiki na sanyi, amfani da dumama kansa don nazarin iskar gas da anemometer da sauran fannoni.
PCT thermistor yana da aikin kiyaye zafin jiki a cikin takamaiman kewayon, kuma yana taka rawar canzawa.Yin amfani da wannan yanayin juriya na zafin jiki azaman tushen dumama, yana kuma iya taka rawar kariya mai zafi don na'urorin lantarki.
2.NTC thermistor
Negative Temperature CoeffiCient (NTC) yana nufin wani abu na thermistor da kayan da ke da ƙarancin zafin jiki mara kyau saboda juriya yana raguwa sosai yayin da zafin jiki ya tashi.Kayan abu shine yumbu mai ɗaukar nauyi wanda aka yi da ƙarfe biyu ko fiye da ƙarfe kamar su manganese, jan karfe, silicon, cobalt, baƙin ƙarfe, nickel, da zinc, waɗanda aka gauraya gabaɗaya, an kafa su, kuma an haɗa su don samar da thermistor tare da ƙimar zafin jiki mara kyau (NTC). ).
Matsayin ci gaba na NTC thermistor: daga gano shi a cikin karni na 19 zuwa ci gabansa a karni na 20, har yanzu ana kammala shi.
Matsakaicin ma'aunin zafi da sanyio zai iya kaiwa 0.1 ℃, kuma lokacin jin zafin jiki na iya zama ƙasa da 10s.Ba wai kawai ya dace da ma'aunin zafin jiki na granary ba, amma kuma ana iya amfani dashi a cikin ajiyar abinci, magani da lafiya, aikin noma na kimiyya, teku, rijiyar zurfi, tsayi mai tsayi, ma'aunin zafin glacier.
3. CTR Thermistor
Critical Temperature Thermistor CTR (Critical Temperature Resistor) yana da halayen juriya mara kyau, a wani zafin jiki, juriya yana raguwa sosai tare da haɓakar zafin jiki kuma yana da babban ƙimar zafin jiki mara kyau.Abun da ke tattare da shi shine vanadium, barium, strontium, phosphorus da sauran abubuwan da ke gauraya sintered jiki, wani semiconductor ne na gilashi, wanda kuma aka sani da CTR don gilashin thermistor.Ana iya amfani da CTR azaman ƙararrawar sarrafa zafin jiki da sauran aikace-aikace.
Hakanan za'a iya amfani da thermistor azaman nau'in kewayawa na lantarki don ramuwa da za'ayi da'irar kayan aiki da diyya na zafin ƙarshen thermocouple sanyi.Ana iya samun ikon sarrafa riba ta atomatik ta amfani da halayen dumama kai na NTC thermistor, kuma ana iya gina da'irar daidaitawa, da'irar jinkiri da da'irar kariyar RC oscillator.Ana amfani da thermistor PTC galibi a cikin kayan aikin lantarki da ke da zafi mai zafi, gudun ba da sanda mara lamba, zazzabi akai-akai, sarrafa riba ta atomatik, fara motar, jinkirin lokaci, lalatawar TV ta atomatik, ƙararrawar wuta da ramuwar zafin jiki, da sauransu.
