Thermistor e kenyelletsa lithempereithara tse ntle tsa mocheso (PTC) le li-thermistor tse mpe (NTC), le li-thermistors tsa bohlokoa tsa mocheso (CTRS).
1.PTC thermistor
Positive Temperature CoeffiCient (PTC) ke ketsahalo ea thermistor kapa thepa e nang le coefficient e ntle ea mocheso le keketseho e matla ea ho hanyetsa mocheso o itseng.E ka sebelisoa e le sensor ea mocheso ea kamehla.Boitsebiso ke 'mele o sintered o nang le BaTiO3, SrTiO3 kapa PbTiO3 e le karolo e ka sehloohong, hape o eketsa li-oxide tsa Mn, Fe, Cu le Cr tse eketsang mocheso o motle oa ho hanyetsa mocheso le lisebelisoa tse ling tse bapalang likarolo tse ling.Thepa e entsoe ka ts'ebetso e tloaelehileng ea ceramic mme e siiloe ka mocheso o phahameng ho etsa titanate ea platinamo le tharollo ea eona e tiileng ea semi-conductive.Kahoo lisebelisoa tsa thermistor tse nang le litšobotsi tse ntle li fumanoa.Thempereichara ea mocheso le mocheso oa ntlha ea Curie li fapana ho ea ka sebopeho le maemo a sintering (haholo-holo mocheso o pholileng).
PTC thermistor e hlahile lekholong la bo20 la lilemo, PTC thermistor e ka sebelisoa bakeng sa tekanyo ea mocheso le taolo indastering, hape e sebelisetsoa ho lemoha mocheso le taolo ea karolo ea koloi, empa hape le lisebelisoa tse ngata tsa sechaba, tse kang ho laola mocheso. mocheso o potlakileng oa metsi a futhumatsang metsi, moea o futhumatsang moea le mocheso oa polokelo o batang, tšebeliso ea ho futhumatsa ha eona bakeng sa tlhahlobo ea khase le anemometer le likarolo tse ling.
PCT thermistor e na le mosebetsi oa ho boloka mocheso sebakeng se itseng, hape o bapala karolo ea ho fetola.Ho sebelisa tšobotsi ena ea ho hanyetsa mocheso e le mohloli oa mocheso, e ka boela ea phetha karolo ea ho sireletsa mocheso o feteletseng bakeng sa lisebelisoa tsa motlakase.
2.NTC thermistor
Negative Temperature CoeffiCient (NTC) e bua ka ketsahalo ea thermistor le thepa e nang le coefficient e mpe ea mocheso hobane khanyetso e fokotseha ka sekhahla ha mocheso o ntse o phahama.Thepa ke semiconducting ceramic e entsoeng ka li-oxide tsa tšepe tse peli kapa ho feta joalo ka manganese, koporo, silicon, cobalt, tšepe, nickel le zinki, tse kopantsoeng ka botlalo, li entsoe, 'me li sintered ho hlahisa thermistor e nang le mocheso o tlase oa mocheso (NTC). ).
Mokhahlelo oa nts'etsopele ea thermistor ea NTC: ho tloha ha e sibolloa lekholong la bo19 la lilemo ho fihlela nts'etsopele ea eona lekholong la bo20 la lilemo, e ntse e etsoa e phethahetseng.
Ho nepahala ha thermometer ea thermistor ho ka fihla ho 0. 1 ℃, 'me nako ea ho utloa mocheso e ka ba ka tlase ho 10s.Ha e loketse feela granary thermometer, empa hape e ka sebelisoa polokelong ea lijo, meriana le bophelo bo botle, temo ea mahlale, leoatle, seliba se tebileng, bophahamo bo phahameng, tekanyo ea mocheso oa leqhoa.
3.CTR thermistor
Critical Temperature Thermistor CTR (Critical Temperature Resistor) e na le tšobotsi e mpe ea ho hanyetsa phetoho, ka mocheso o itseng, ho hanyetsa ho fokotseha haholo ka ho eketseha ha mocheso 'me ho na le mocheso o mongata o mobe.Thepa ea motsoako ke vanadium, barium, strontium, phosphorus le likarolo tse ling tsa 'mele o kopantsoeng oa sintered, ke semiconductor ea semi-glass, e tsejoang hape e le CTR bakeng sa mocheso oa khalase.CTR e ka sebelisoa e le alamo ea taolo ea mocheso le lits'ebetso tse ling.
Thermistor e ka boela ea sebelisoa e le karolo ea potoloho ea elektroniki bakeng sa matšeliso a mocheso oa potoloho ea sesebelisoa le matšeliso a mocheso oa pheletso e batang ea thermocouple.Ho laola ka mokhoa o itekanetseng ho ka etsoa ka ho sebelisa mokhoa oa ho futhumatsa oa NTC thermistor, 'me potoloho ea amplitude stabilization, potoloho ea ho lieha le potoloho ea tšireletso ea RC oscillator e ka hahoa.Thermistor ea PTC e sebelisoa haholo ts'ireletsong ea mocheso o feteletseng oa lisebelisoa tsa motlakase, phepelo e sa amaneng le motho, mocheso o sa khaotseng, taolo ea othomathike, ho qala koloi, ho lieha ha nako, ho senyeha ha 'mala oa TV, alamo ea mollo le matšeliso a mocheso, joalo-joalo.
