Chii chinonzi thermostat?
Matemperature controllers ane mazita akasiyana siyana, akadai setembiricha yekudzora switch, zvidziviriri zvetembiricha uye zvinodzora tembiricha. Zvinoenderana nemusimboti wekushanda, inogona kukamurwa kuita jump type thermostat, liquid type thermostat, pressure type thermostat uye electronic type thermostat. Mumidziyo yemazuva ano yekudzora maindasitiri, digital thermostat ndiyo inonyanya kushandiswa mhando. Zvinoenderana nechimiro, tembiricha controller inogona kukamurwa kuita yakasanganiswa tembiricha controller uye modular tembiricha controller.
Chii chinonzi thermometers?
Muviri wekuyera tembiricha chikamu chinoshandura chiratidzo chekushisa kuita chiratidzo chemagetsi, uye chinowanzoiswa muchikamu chekuona chechinhu chinodzorwa kuti chitarise kukosha kwayo kwekushisa. Mumunda wekutonga kwemaindasitiri, ma thermometers anowanzoshandiswa anosanganisira thermocouples, thermal resistors, thermistors uye non-contact sensors. Pakati pavo, matatu ekutanga ndeyekubata thermometers.
1. Thermocouple
Nheyo yekuyera kuyerwa kwekushisa kwe thermocouples yakavakirwa paSeebeck athari (thermoelectric effect). Kana simbi mbiri dzezvinhu zvakasiyana (kazhinji maconductor kana semiconductors, senge platinum-rhodium, nickel-chromium-nickel-silicon uye zvimwe zvinhu zvakapetwa) zvinogadzira chivharo chakavharwa uye kushandisa tembiricha dzakasiyana kumigumo yadzo mbiri dzinobatanidza, simba re electromotive rinogadzirwa pakati. simbi mbiri. Loop yakadaro inonzi "thermocouple," nepo simbi mbiri dzinonzi "thermal electrode," uye inoguma electromotive simba inonzi "thermoelectric motive force." Thermocouples inoratidzirwa nehupamhi hwekuyeresa tembiricha renji, kukurumidza kupisa kwemhinduro, uye yakasimba vibration kuramba.
2. Thermal resistance
Thermal resistance inhengo inoshandura chiratidzo chetembiricha kuita chiratidzo chemagetsi, uye misimboti yayo yekushanda inonyanya kuenderana nehunhu hwekuchinja kwesimbi nekupisa. Kunyanya, thermal resistors inotora mukana weiyo pfuma yesimbi kuyera tembiricha.
Mukutonga kwemaindasitiri, marudzi anowanzo shandiswa ekupisa kupisa anosanganisira platinamu, mhangura uye nickel. Pakati pavo, kuramba kweplatinamu ndiyo yakajairika. Thermal resistance ine hunhu hwekunaka tembiricha mutsara, kuita kwakagadzikana uye kurongeka kwepamusoro mumunda wekudziya kwakajairika. Nokudaro, munzvimbo yekushandiswa kwekushisa kwepakati, pasina kuzununguka uye yakakwirira chaiyo zvinodiwa, kushandiswa kweplatinamu kuramba kunowanzodiwa.
3. Thermistor
Thermistor chinhu chinoshandura chiratidzo chekushisa kuita chiratidzo chemagetsi, uye nheyo yayo yekushanda inonyanya kuenderana nehunhu hwekupikisa kwesemiconductor kuchinja nekupisa. Kunyanya, ma thermistors anotora mukana weiyi pfuma ye semiconductors kuyera tembiricha. Kuenzaniswa nekupikiswa kwekupisa, kuramba kwe thermistor kunoshanduka zvakanyanya nekuchinja kwekushisa, saka tembiricha yayo yekuyera huwandu hwakatetepa (-50 ~ 350 ℃).
Thermistors yakakamurwa kuita NTC thermistors uye PTC thermistors. NTC thermistors ine yakashata tembiricha coefficient, uye kuramba kwavo kukosha kunoderera sezvo tembiricha inowedzera. PTC thermistor ine yakanaka tembiricha coefficient, uye kukosha kwayo kwekudzivirira kuchawedzera nekuwedzera kwekushisa. Nekuda kweakasarudzika ekupikisa tembiricha maitiro, thermistor ine huwandu hwakasiyana hwekushandisa mukuona tembiricha, otomatiki kudzora, zvigadzirwa zvemagetsi uye mamwe minda.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa MG&MAUXS zvikamu zvemotokari zvinogamuchirwa kutenga.
