Tsanangura zvakadzama mamiriro ekuyerwa kwekushisa kwe thermocouple

Thermocoupleimhando yetembiricha inonzwa chinhu, imhando yechiridzwa, thermocouple inoyera tembiricha yakananga. Iyo yakavharwa loop inoumbwa nemakondakita maviri ane akasiyana ekugadzira zvinhu. Nekuda kwezvinhu zvakasiyana-siyana, maerekitironi akasiyana-siyana anoburitsa maerekitironi diffusion, uye mukana unogadzirwa mushure mekuenzanisa kwakagadzikana. Kana paine tembiricha yegradient kumativi ese ari maviri, ikozvino inogadzirwa muchiuno, uye iyo thermoelectromotive simba inogadzirwa. Iyo yakakura musiyano wetembiricha, iyo yakakura ikozvino. Mushure mekuyera simba re thermoelectromotive, kukosha kwekushisa kunogona kuzivikanwa. Mukuita, thermocouple isimba rinoshandura rinoshandura simba rekupisa kuita simba remagetsi.

Izvo zvehunyanzvi zvakanakira ma thermocouples:thermocoupleskuva nehupamhi hwekuyera kuyera kwekushisa uye kuita kwakagadzikana; chiyero chepamusoro chechiyero, iyo thermocouple inosangana zvakananga nechinhu chakayerwa, uye haina kukanganiswa nepakati pepakati; nguva yekupindura inopisa inokurumidza, uye thermocouple inonzwa kuchinja kwekushisa; Chiyero chekuyera chakakura, iyo thermocouple inogona kuyera tembiricha ichienderera kubva -40~+1600℃; thethermocoupleine yakavimbika mashandiro uye akanaka echimakanika simba. Hupenyu hwehupenyu hwakareba uye kuiswa kuri nyore. Vaviri vegalvanic vanofanirwa kunge vakaumbwa nemaviri conductor (kana semiconductor) zvinhu zvine zvivakwa zvakasiyana asi vachizadzisa zvimwe zvinodiwa kuti vagadzire chiuno. Panofanirwa kuve nemusiyano wekupisa pakati penzvimbo yekuyera nereferensi terminal yeiyo thermocouple.

Iwo ma conductor kana semiconductors A uye B yezvinhu zviviri zvakasiyana zvakasunganidzwa pamwechete kuti vagadzire chiuno chakavharwa. Kana paine musiyano wekupisa pakati pezvikamu zviviri zvekubatanidza 1 ne2 zvevafambisi A naB, simba remagetsi rinogadzirwa pakati pezviviri, nokudaro richiumba ruzha rukuru muchiuno. Ichi chinoshamisa chinonzi iyo thermoelectric athari. Thermocouples anoshanda achishandisa izvi.
